Under ASC 606, revenue is measured based on a consideration specified in a customer&#8217;s contract, excluding any sale incentives and taxes collected on behalf of third parties (i.e. sales and property taxes). Revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration that we expect to receive for those goods or services. To recognize revenue, we (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, we satisfy the performance obligation(s).

After the initial term of our rental contracts, many of our customers have continued to rent our compressors on a month-to-month basis.

Fabrication of compressors involves our purchase of engines, compressors, coolers, and other components, and our assembling of these components on skids for delivery to customer locations. The major components of our compressor packages are acquired through periodic purchase orders placed with third-party suppliers on an &#8220;as needed&#8221; basis, which presently require lead times between two to three months with delivery dates scheduled to coincide with our estimated production schedules. Although we do not have formal continuing supply contracts with any major supplier, we believe we have adequate alternative sources available. In the past, we have not experienced any sudden and dramatic increases in the prices of the major components for our compressors; however, the occurrence of such an event could have a material adverse effect on the results of our operations and financial condition, particularly if we were unable to increase our rental rates and sales prices proportionate to any such component price increases.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We also manufacture a proprietary line of compressor frames, cylinders and parts, known as our CiP (Cylinder-in-Plane) product line. We use finished CiP component products in the fabrication of compressor units for sale or rental by us or sell the finished component products to other compressor fabricators. We also design, fabricate, sell, install, and service flare stacks and related ignition and control devices for onshore and offshore incineration of gas compounds such as hydrogen sulfide, carbon dioxide, natural gas and liquefied petroleum gases. To provide customer support for our compressor and flare sales businesses, we stock varying levels of replacement parts at our Midland, Texas facility and at field service locations. We also provide an exchange and rebuild program for screw compressors and maintain an inventory of new and used compressors to facilitate this business.</span></div><div><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We provide service and maintenance to our customers under written maintenance contracts or on an as-required basis in the absence of a service contract.

The most critical factor in assessing the outlook for the industry is the worldwide supply and demand for oil and natural gas and the corresponding changes in commodity prices.  As demand and prices increase, oil and natural gas producers typically increase their capital expenditures for drilling, development and production activities, although recent equity capital constraints and demands from institutional investors to keep spending within operating cash flow have meaningfully restrained capital expenditure budgets of domestic exploration and production companies.  Generally, increased capital expenditures ultimately result in greater revenues and profits for service and equipment companies.</span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In general, we expect our overall business activity and revenues to track the level of activity in the oil and natural gas industry, with changes in crude oil and condensate production and consumption levels and prices affecting our business more than changes in domestic natural gas production and consumption levels and prices. In recent years we have increased our rentals and sales in unconventional oil shale plays, which are more dependent on crude oil prices. With this shift towards oil production, the demand for overall compression services and products is driven by two general factors: an increased focus by producers on artificial lift applications, e.g., production enhancement with compression assisted gas lift; and declining reservoir pressure in maturing natural gas producing fields, especially unconventional production. These types of applications have historically been serviced by wellhead size compressors, and continue to be, but there has also been an economic move by our customers towards centralized drilling and production facilities, which have increased the market need for larger horsepower compressor packages. We recognized this need in recent years and have been shifting our cash and fabrication resources towards designing, fabricating and renting gas compressor packages that range from 400 horsepower up to 1,380 horsepower. While this is a response to market conditions and trends, it also provides us with the opportunity to compete as a full-line compression provider.</span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Industry Update</span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We typically experience a decline in demand during periods of low crude oil and natural gas prices.  During the first quarter of 2020, we saw a substantial decline in the prices for oil and natural gas.  While commodity prices have stabilized during late 2020 and through the first nine months of 2021, activity levels of exploration and production companies have been and will be dependent not only on commodity prices, but also on their ability to generate sufficient operational cash flow to fund their activities. Generally, though, we feel that production activities (in which we are involved) will fare better than drilling activity. This is reflected in both the stability of our rental revenues, which is driven by production activities, and the volatility of our compressor sales, which tends to fluctuate with drilling activity.  </span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">On January 30, 2020, the World Health Organization (&#8220;WHO&#8221;) announced a global health emergency because of a new strain of coronavirus known as COVID-19 due to the risks it imposes on the international community as the virus spreads globally.  In March 2020, the WHO classified the COVID-19 outbreak as a pandemic, based on the rapid increase in exposure globally.  The effects of the COVID-19 outbreak, including actions taken by businesses and governments to contain the spread of the virus, resulted in a significant, rapid decline in global and U.S. economic conditions.  This significant drop in economic activity caused global demand for crude oil to drastically decline.          </span></div><div style="text-indent:36pt"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">While oil and natural gas prices have recovered from these historic lows, we still expect compressor sales to be low for the remainder of 2021, as exploration and production companies have elected to rent compression units rather than allocating capital dollars to purchase new compression.</span></div><div style="text-indent:36pt"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Finally, in keeping with current commercial precautions and practices in our industry, we have implemented guidelines to mitigate health risks to our employees and customers during this outbreak.

Under ASC 606, revenue is measured based on a consideration specified in a customer&#x2019;s contract, excluding any sale incentives and taxes collected on behalf of third parties (i.e. sales and property taxes). Revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration that we expect to receive for those goods or services. To recognize revenue, we (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, we satisfy the performance obligation(s). Shipping and handling costs incurred are accounted for as fulfillment costs and are included in cost of revenues in our condensed consolidated statements of operations. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Nature of Goods and Services&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The following is a description of principal activities from which the Company generates its revenue: &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Rental Revenue.  &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company generates revenue from renting compressors and flare systems to our customers.  These contracts, which all qualify as operating leases under ASC Topic 842, Leases (ASC 842), may also include a fee for servicing the compressor or flare during the rental contract period. Our rental contracts typically range from &lt;span style="-sec-ix-hidden:id3VybDovL2RvY3MudjEvZG9jOjBkOGJjYWFmMDUxYTRlMmZhNmU5NWJiNDUzOTcxNTc5L3NlYzowZDhiY2FhZjA1MWE0ZTJmYTZlOTViYjQ1Mzk3MTU3OV8zNy9mcmFnOjM1M2YyNWE5Mjg4YTQ2MTZhZDc0MDI5ZmM4MDU0MDY5L3RleHRyZWdpb246MzUzZjI1YTkyODhhNDYxNmFkNzQwMjlmYzgwNTQwNjlfMzA1Mw_02d5ce0b-17e8-4887-90e3-2c6273b274bb"&gt;six&lt;/span&gt; to 24 months, with our larger horsepower compressors having contract terms of up to 60 months. Our revenue is recognized over time, with equal monthly payments over the term of the contract. After the terms of the contract have expired, a customer may renew their contract or continue renting on a monthly basis thereafter. In accordance ASC 842, we have applied the practical expedient ASC 842-10-15-42A, which allows the Company to combine lease and non-lease components.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:115%"&gt;Sales Revenue.  &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"&gt;The Company generates revenue by the sale of custom/fabricated compressors, flare systems and parts, as well as, exchange/rebuilding customer owned compressors and sale of used rental equipment.  &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;Custom/fabricated compressors and flare systems&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; - The Company designs and fabricates compressors and flares based on the customer&#x2019;s specifications outlined in their contract. Though the equipment being built is customized by the customer, control under these contracts does not pass to the customer until the compressor or flare package is complete and shipped, or in accordance with a bill and hold arrangement, the customer accepts title and assumes the risk and rewards of ownership. We request some of our customers to make progressive payments as the product is being built; these payments are recorded as a contract liability on the Deferred Income line on the condensed consolidated balance sheet until control has been transferred. These contracts also may include an assurance warranty clause to guarantee the product is free from defects in material and workmanship for a set duration of time; this is a standard industry practice and is not considered a performance obligation. &lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:72pt;text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt;text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;From time to time we recognize revenue when manufacturing is complete and the equipment is ready for shipment. At the customer&#x2019;s request, we will bill the customer upon completing all performance obligations, but before shipment. The customer will formally request that we ship the equipment per their direction from our manufacturing facility at a later specified date and that we segregate the equipment from our finished goods, such that they are not available to fill other orders. Per the customer&#x2019;s agreement change of control is passed to the customer once the equipment is complete and ready for shipment. We have operated using bill and hold agreements with certain customers for many years, with consistent and satisfactory results for both the customer and us. The credit terms on these agreements are consistent with the credit terms on all other sales. All control is maintained by the customer and there are no exceptions to the customer&#x2019;s commitment to accept and pay for the manufactured equipment. There was no revenue recognized for bill and hold arrangements for the nine months ended September 30, 2021. Revenue recognized related to bill and hold arrangements for the nine months ended September 30, 2020 was approximately $852,000.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;Parts&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt; - &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Revenue is recognized after the customer obtains control of the parts. Control is passed either by the customer taking physical possession or the parts being shipped. The amount of revenue recognized is not adjusted for expected returns, as our historical part returns have been de minimis. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%;text-decoration:underline"&gt;Exchange or rebuilding customer owned compressors&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"&gt; - Based on the contract, the Company will either exchange a new/rebuilt compressor for the customer&#x2019;s malfunctioning compressor or rebuild the customer&#x2019;s compressor. Revenue is recognized after control of the replacement compressor has transferred to the customer based on the terms of the contract, i.e., by physical delivery, delivery and installment, or shipment of the compressor.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%;text-decoration:underline"&gt;Used compressors or flares&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"&gt; - From time to time, a customer may request to purchase a used compressor or flare out of our rental fleet. Revenue from the sale of rental equipment is recognized when the control has passed to the customer based on the terms of the contract, i.e., when the customer has taken physical possession or the equipment has been shipped.&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:72pt;text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Service and Maintenance Revenue&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;.

Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  Valuation allowances are established to reduce deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not be realized. To the extent we establish a valuation allowance or increase this allowance in a period, we include an expense in the tax provision in our condensed consolidated statements of operations.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We account for uncertain tax positions in accordance with guidance in ASC 740, which prescribes the minimum recognition threshold a tax position taken or expected to be taken in a tax return is required to meet before being recognized in the condensed consolidated financial statements. Tax benefits are recognized only for tax positions that are more likely than not to be sustained upon examination by tax authorities.  The amount recognized is measured as the largest amount of benefit that is greater than 50% likely to be realized upon settlement.  A liability for unrecognized tax benefits is recorded for any tax benefits claimed in our tax returns that do not meet these recognition and measurement standards.  We have no liabilities for uncertain tax positions as of September 30, 2021.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Our policy regarding income tax interest and penalties is to expense those items as interest expense and other expense, respectively.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") was enacted in response to the economic impact caused by the COVID-19 pandemic. The CARES Act, among other things, permits federal income tax net operating loss ("NOL") carryovers and carrybacks to offset 100% of taxable income for taxable years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid federal income taxes.  Please see Note 4, Federal Income Tax Receivable for a discussion about the impact on our condensed consolidated financial statements.     &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:115%"&gt;Recently Issued Accounting Pronouncements&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (ASC Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments to ASC Topic 326 require immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets, including trade receivables. For companies that qualify as smaller reporting companies, the amendments in this update are effective for interim and annual periods beginning after January 1, 2023. We are currently evaluating the impact of ASU 2016-13 on our consolidated financial statements and note disclosures.&lt;/span&gt;&lt;/div&gt;</us-gaap:BasisOfPresentationAndSignificantAccountingPoliciesTextBlock>

Under ASC 606, revenue is measured based on a consideration specified in a customer&#x2019;s contract, excluding any sale incentives and taxes collected on behalf of third parties (i.e. sales and property taxes). Revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration that we expect to receive for those goods or services. To recognize revenue, we (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, we satisfy the performance obligation(s). Shipping and handling costs incurred are accounted for as fulfillment costs and are included in cost of revenues in our condensed consolidated statements of operations. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Nature of Goods and Services&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The following is a description of principal activities from which the Company generates its revenue: &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Rental Revenue.  &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company generates revenue from renting compressors and flare systems to our customers.  These contracts, which all qualify as operating leases under ASC Topic 842, Leases (ASC 842), may also include a fee for servicing the compressor or flare during the rental contract period. Our rental contracts typically range from &lt;span style="-sec-ix-hidden:id3VybDovL2RvY3MudjEvZG9jOjBkOGJjYWFmMDUxYTRlMmZhNmU5NWJiNDUzOTcxNTc5L3NlYzowZDhiY2FhZjA1MWE0ZTJmYTZlOTViYjQ1Mzk3MTU3OV8zNy9mcmFnOjM1M2YyNWE5Mjg4YTQ2MTZhZDc0MDI5ZmM4MDU0MDY5L3RleHRyZWdpb246MzUzZjI1YTkyODhhNDYxNmFkNzQwMjlmYzgwNTQwNjlfMzA1Mw_02d5ce0b-17e8-4887-90e3-2c6273b274bb"&gt;six&lt;/span&gt; to 24 months, with our larger horsepower compressors having contract terms of up to 60 months. Our revenue is recognized over time, with equal monthly payments over the term of the contract. After the terms of the contract have expired, a customer may renew their contract or continue renting on a monthly basis thereafter. In accordance ASC 842, we have applied the practical expedient ASC 842-10-15-42A, which allows the Company to combine lease and non-lease components.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:115%"&gt;Sales Revenue.  &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"&gt;The Company generates revenue by the sale of custom/fabricated compressors, flare systems and parts, as well as, exchange/rebuilding customer owned compressors and sale of used rental equipment.  &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;Custom/fabricated compressors and flare systems&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; - The Company designs and fabricates compressors and flares based on the customer&#x2019;s specifications outlined in their contract. Though the equipment being built is customized by the customer, control under these contracts does not pass to the customer until the compressor or flare package is complete and shipped, or in accordance with a bill and hold arrangement, the customer accepts title and assumes the risk and rewards of ownership. We request some of our customers to make progressive payments as the product is being built; these payments are recorded as a contract liability on the Deferred Income line on the condensed consolidated balance sheet until control has been transferred. These contracts also may include an assurance warranty clause to guarantee the product is free from defects in material and workmanship for a set duration of time; this is a standard industry practice and is not considered a performance obligation. &lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:72pt;text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt;text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;From time to time we recognize revenue when manufacturing is complete and the equipment is ready for shipment. At the customer&#x2019;s request, we will bill the customer upon completing all performance obligations, but before shipment. The customer will formally request that we ship the equipment per their direction from our manufacturing facility at a later specified date and that we segregate the equipment from our finished goods, such that they are not available to fill other orders. Per the customer&#x2019;s agreement change of control is passed to the customer once the equipment is complete and ready for shipment. We have operated using bill and hold agreements with certain customers for many years, with consistent and satisfactory results for both the customer and us. The credit terms on these agreements are consistent with the credit terms on all other sales. All control is maintained by the customer and there are no exceptions to the customer&#x2019;s commitment to accept and pay for the manufactured equipment. There was no revenue recognized for bill and hold arrangements for the nine months ended September 30, 2021. Revenue recognized related to bill and hold arrangements for the nine months ended September 30, 2020 was approximately $852,000.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;Parts&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt; - &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Revenue is recognized after the customer obtains control of the parts. Control is passed either by the customer taking physical possession or the parts being shipped. The amount of revenue recognized is not adjusted for expected returns, as our historical part returns have been de minimis. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%;text-decoration:underline"&gt;Exchange or rebuilding customer owned compressors&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"&gt; - Based on the contract, the Company will either exchange a new/rebuilt compressor for the customer&#x2019;s malfunctioning compressor or rebuild the customer&#x2019;s compressor. Revenue is recognized after control of the replacement compressor has transferred to the customer based on the terms of the contract, i.e., by physical delivery, delivery and installment, or shipment of the compressor.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%;text-decoration:underline"&gt;Used compressors or flares&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"&gt; - From time to time, a customer may request to purchase a used compressor or flare out of our rental fleet. Revenue from the sale of rental equipment is recognized when the control has passed to the customer based on the terms of the contract, i.e., when the customer has taken physical possession or the equipment has been shipped.&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:72pt;text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Service and Maintenance Revenue&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;. The Company provides routine or call-out services on customer owned equipment. Revenue is recognized after services in the contract are rendered. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Payment terms for sales revenue and service and maintenance revenue discussed above are generally 30 to 60 days, although terms for specific customers can vary.

These costs are included in selling, general and administrative expenses on our condensed consolidated statements of operations.&lt;/span&gt;&lt;/div&gt;</us-gaap:RevenueFromContractWithCustomerPolicyTextBlock>

Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  Valuation allowances are established to reduce deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not be realized. To the extent we establish a valuation allowance or increase this allowance in a period, we include an expense in the tax provision in our condensed consolidated statements of operations.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We account for uncertain tax positions in accordance with guidance in ASC 740, which prescribes the minimum recognition threshold a tax position taken or expected to be taken in a tax return is required to meet before being recognized in the condensed consolidated financial statements. Tax benefits are recognized only for tax positions that are more likely than not to be sustained upon examination by tax authorities.  The amount recognized is measured as the largest amount of benefit that is greater than 50% likely to be realized upon settlement.  A liability for unrecognized tax benefits is recorded for any tax benefits claimed in our tax returns that do not meet these recognition and measurement standards.  We have no liabilities for uncertain tax positions as of September 30, 2021.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Our policy regarding income tax interest and penalties is to expense those items as interest expense and other expense, respectively.&lt;/span&gt;&lt;/div&gt;On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") was enacted in response to the economic impact caused by the COVID-19 pandemic. The CARES Act, among other things, permits federal income tax net operating loss ("NOL") carryovers and carrybacks to offset 100% of taxable income for taxable years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid federal income taxes.</us-gaap:IncomeTaxPolicyTextBlock>

The Company generated significant NOLs during 2018 and 2019, and has filed amended returns to carryback these losses for five years.  Accordingly, during 2020, the Company recorded a federal income tax receivable of $15.0&#160;million and an increase to its deferred income tax liability of $10.1&#160;million on its condensed consolidated balance sheet.  During the third quarter of 2020, the Company received refunds totaling $3.9&#160;million related to its 2018 NOLs, which reduced its federal income tax receivable to $11.5 million on its condensed consolidated balance sheet as of September 30, 2021.</us-gaap:IncomeTaxDisclosureTextBlock>

We also have a right to request from the Lender, on an uncommitted basis, an increase of up to $30 million on the aggregate commitment; provided, however, the aggregate commitment amount is not permitted to exceed $50 million. The maturity date of the New Credit Agreement is May 11, 2026. The obligations under the New Credit Agreement are secured by a first priority lien on a variety of our assets, including inventory and accounts receivable as well as a variable number of our leased compressor equipment.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:103%"&gt;Borrowing Base.&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:103%"&gt; At any time before the maturity of the New Credit Agreement, we may draw, repay and re-borrow amounts available under the borrowing base up to the maximum aggregate availability discussed above.

The Lender may adjust the borrowing base components if material deviations in the collateral are discovered in future audits of the collateral.

"Base Rate" means, for any day, a rate of interest per annum equal to the highest of (a) the prime rate for such day; (b) the sum of the federal funds rate for such day plus 0.50%; and (c) the Adjusted Eurodollar Rate for such day plus 1.00%. The Applicable Margin is determined based upon the leverage ratio as set forth in the most recent compliance certificate received by the Lender for each fiscal quarter from time to time pursuant to the New Credit Agreement. Depending on the leverage ratio, the Applicable Margin can be 0.25% to 0.75% for Base Rate Loans (as defined in the New Credit Agreement) and 1.25% to 1.75% for Eurodollar Rate Loans and for requested letters of credit. In addition, we are required to pay a monthly commitment fee on the daily average unused amount of the commitment while the New Credit Agreement is in effect at an annual rate equal to 0.25% of the unused commitment amount. Accrued interest is payable monthly on outstanding principal amounts and unused commitment fee, provided that accrued interest on Eurodollar Rate Loans is payable at the end of each interest period, but in no event less frequently than quarterly.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:103%"&gt;Covenants.&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:103%"&gt; The New Credit Agreement contains customary representations and warranties, as well as covenants which, among other things, condition or limit our ability to incur additional indebtedness and liens; enter into transactions with affiliates; make acquisitions in excess of certain amounts; pay dividends; redeem or repurchase capital stock or senior notes; make investments or loans; make negative pledges; consolidate, merge or effect asset sales; or change the nature of our business. In addition, we also have certain financial covenants that are applicable during certain trigger periods specified in the Credit Agreement and require us during such trigger periods to maintain a leverage ratio less than or equal to 3.00 to 1.00 as of the last day of each fiscal quarter and a fixed charge coverage ratio greater than or equal to 1.00 to 1.00 as of the last day of each fiscal quarter.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:103%"&gt;Events of Default and Acceleration.&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:103%"&gt; The New Credit Agreement contains customary events of default for credit facilities of this size and type, and includes, without limitation, payment defaults; defaults in performance of covenants or other agreements contained in the Credit Agreement and the other transaction documents; inaccuracies in representations and warranties; certain defaults, termination events or similar events; certain defaults with respect to any other Company indebtedness in excess of $1.0 million; certain bankruptcy or insolvency events; the rendering of certain judgments in excess of $1.0 million; certain ERISA events; certain change in control events and the defectiveness of any liens under the secured revolving credit agreement.

award of $1.1 million to Mr. Taylor that vests in equal, annual tranches over 3 years beginning on the anniversary of the grant date.  At the time of vesting, each tranche was or will be payable in cash or common stock at the discretion of the Compensation Committee.  On March 18, 2021, based on its review of Mr. Taylor's 2020 performance, the Compensation Committee issued a long-term incentive award of $973,080 to Mr. Taylor that vests in equal, annual tranches over 3 years beginning on the anniversary of the grant date. In addition, on April 28, 2020, we issued a $50,000 award to three of our independent members of our Board of Directors as partial payment for their services in 2020.  These awards vest one year from the date of grant and are payable in cash upon vesting. On March 18, 2021, we issued a $50,000 award to three of our independent members of our Board of Directors as partial payment for their services in 2021. On April 1, 2021, we issued a $50,000 award to a newly appointed independent member of our Board of Directors as partial payment for his services in 2021. These awards vest one year from the date of grant and are payable in cash upon vesting. The Company accounts for these other long-term incentive awards to Mr. Taylor and our independent Board members as liabilities under accrued liabilities on our condensed consolidated balance sheet.  The vesting of these awards awards is subject to acceleration upon certain events, such as (i) death or disability of the recipient,  (ii) certain circumstances in connection with a change of control of the Company, (iii) for executive officers, termination without cause (as defined in the agreement), and (iv) for executive officers, resignation for good reason (as defined).  Total compensation expense related to these other long-term incentive awards was approximately $600,000 and $252,000 for the nine months ended September 30, 2021 and 2020, respectively. As of September 30, 2021, there was a total of $1.4 million of unrecognized compensation expense related to these other long-term incentive awards which is expected to be recognized over the next 2.0 years.&lt;/span&gt;&lt;/div&gt;</us-gaap:DisclosureOfCompensationRelatedCostsShareBasedPaymentsTextBlock>

The timing and extent of any repurchase is subject to the discretion of management and is dependent upon market pricing and conditions, business, legal, accounting and other considerations. The repurchase program does not obligate the Company to purchase any shares and was set to expire on September 30, 2020, subject to earlier termination of the program by the Board of Directors. On October 23, 2020, the Board of Directors authorized the extension of the repurchase program through September 30, 2021. The repurchase program may be modified, suspended or terminated at any time without notice, in the Company&#x2019;s discretion, based upon a number of factors, including market conditions, the cost of repurchasing shares, the availability of alternative investment opportunities, liquidity, the need for capital in the Company&#x2019;s operations and other factors deemed appropriate. The Company intends to finance the repurchases with existing liquidity and free cash flow. For the nine months ended September 30, 2021, the Company repurchased 432,731 of its outstanding shares of common stock with a value of $4.4 million, at an average price of $10.24. As of September 30, 2021, the expiration date of the plan, the Company had repurchased 470,667 of its outstanding shares of common stock with a value of $4.9 million, at an average price of $10.46. On September 30, 2021, the Board of Directors authorized a new repurchase plan for up to $10.0 million of its outstanding shares of common stock in the open market, block trades or privately negotiated transactions. The terms of the new plan remain unchanged from the terms of the plan that expired on September 30, 2021.

Under ASC 606, revenue is measured based on a consideration specified in a customer&#8217;s contract, excluding any sale incentives and taxes collected on behalf of third parties (i.e. sales and property taxes). Revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration that we expect to receive for those goods or services. To recognize revenue, we (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, we satisfy the performance obligation(s). Shipping and handling costs incurred are accounted for as fulfillment costs and are included in cost of revenues in our condensed consolidated statements of operations. </span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Nature of Goods and Services</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The following is a description of principal activities from which the Company generates its revenue: </span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Rental Revenue.  </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company generates revenue from renting compressors and flare systems to our customers.

We request some of our customers to make progressive payments as the product is being built; these payments are recorded as a contract liability on the Deferred Income line on the condensed consolidated balance sheet until control has been transferred. These contracts also may include an assurance warranty clause to guarantee the product is free from defects in material and workmanship for a set duration of time; this is a standard industry practice and is not considered a performance obligation. </span></div><div style="padding-left:72pt;text-align:justify"><span><br/></span></div><div style="margin-bottom:10pt;text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">From time to time we recognize revenue when manufacturing is complete and the equipment is ready for shipment. At the customer&#8217;s request, we will bill the customer upon completing all performance obligations, but before shipment. The customer will formally request that we ship the equipment per their direction from our manufacturing facility at a later specified date and that we segregate the equipment from our finished goods, such that they are not available to fill other orders. Per the customer&#8217;s agreement change of control is passed to the customer once the equipment is complete and ready for shipment. We have operated using bill and hold agreements with certain customers for many years, with consistent and satisfactory results for both the customer and us. The credit terms on these agreements are consistent with the credit terms on all other sales. All control is maintained by the customer and there are no exceptions to the customer&#8217;s commitment to accept and pay for the manufactured equipment.

The amount recognized is measured as the largest amount of benefit that is greater than 50% likely to be realized upon settlement.

<td class="text">Federal Income Tax ReceivableAs discussed in Note 2, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid federal income taxes.  The Company generated significant NOLs during 2018 and 2019, and has filed amended returns to carryback these losses for five years.  Accordingly, during 2020, the Company recorded a federal income tax receivable of $15.0&#160;million and an increase to its deferred income tax liability of $10.1&#160;million on its condensed consolidated balance sheet.  During the third quarter of 2020, the Company received refunds totaling $3.9&#160;million related to its 2018 NOLs, which reduced its federal income tax receivable to $11.5 million on its condensed consolidated balance sheet as of September 30, 2021.<span></span>

anniversary of the grant date.  At the time of vesting, each tranche was or will be payable in cash or common stock at the discretion of the Compensation Committee.  On March 18, 2021, based on its review of Mr. Taylor's 2020 performance, the Compensation Committee issued a long-term incentive award of $973,080 to Mr. Taylor that vests in equal, annual tranches over 3 years beginning on the anniversary of the grant date. In addition, on April 28, 2020, we issued a $50,000 award to three of our independent members of our Board of Directors as partial payment for their services in 2020.  These awards vest one year from the date of grant and are payable in cash upon vesting. On March 18, 2021, we issued a $50,000 award to three of our independent members of our Board of Directors as partial payment for their services in 2021. On April 1, 2021, we issued a $50,000 award to a newly appointed independent member of our Board of Directors as partial payment for his services in 2021. These awards vest one year from the date of grant and are payable in cash upon vesting. The Company accounts for these other long-term incentive awards to Mr. Taylor and our independent Board members as liabilities under accrued liabilities on our condensed consolidated balance sheet.  The vesting of these awards awards is subject to acceleration upon certain events, such as (i) death or disability of the recipient,  (ii) certain circumstances in connection with a change of control of the Company, (iii) for executive officers, termination without cause (as defined in the agreement), and (iv) for executive officers, resignation for good reason (as defined).  Total compensation expense related to these other long-term incentive awards was approximately $600,000 and $252,000 for the nine months ended September 30, 2021 and 2020, respectively. As of September 30, 2021, there was a total of $1.4 million of unrecognized compensation expense related to these other long-term incentive awards which is expected to be recognized over the next 2.0 years.</span></div><span></span>

The timing and extent of any repurchase is subject to the discretion of management and is dependent upon market pricing and conditions, business, legal, accounting and other considerations. The repurchase program does not obligate the Company to purchase any shares and was set to expire on September 30, 2020, subject to earlier termination of the program by the Board of Directors. On October 23, 2020, the Board of Directors authorized the extension of the repurchase program through September 30, 2021. The repurchase program may be modified, suspended or terminated at any time without notice, in the Company&#8217;s discretion, based upon a number of factors, including market conditions, the cost of repurchasing shares, the availability of alternative investment opportunities, liquidity, the need for capital in the Company&#8217;s operations and other factors deemed appropriate. The Company intends to finance the repurchases with existing liquidity and free cash flow. For the nine months ended September 30, 2021, the Company repurchased 432,731 of its outstanding shares of common stock with a value of $4.4 million, at an average price of $10.24. As of September 30, 2021, the expiration date of the plan, the Company had repurchased 470,667 of its outstanding shares of common stock with a value of $4.9 million, at an average price of $10.46. On September 30, 2021, the Board of Directors authorized a new repurchase plan for up to $10.0 million of its outstanding shares of common stock in the open market, block trades or privately negotiated transactions. The terms of the new plan remain unchanged from the terms of the plan that expired on September 30, 2021.

Revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration that we expect to receive for those goods or services. To recognize revenue, we (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, we satisfy the performance obligation(s).
