Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Reporting for Consolidated Financial Statements	1. Basis of Reporting for Consolidated Financial Statements The accompanying unaudited condensed consolidated financial statements of CECO Environmental Corp. and its subsidiaries (the “Company,” “CECO,” “we,” “us,” or “our”) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to those rules and regulations. In the opinion of management, the accompanying unaudited condensed consolidated financial statements of the Company contain all adjustments, consisting only of normal recurring adjustments, necessary to present fairly the financial position as of September 30, 2024 and the results of operations, cash flows and shareholders’ equity for the three and nine months ended September 30, 2024 and 2023. The results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of the results to be expected for the full year. The balance sheet as of December 31, 2023 has been derived from the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 as filed with the SEC on March 5, 2024 (the “Form 10-K”). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. These financial statements and accompanying notes should be read in conjunction with the audited financial statements and the notes thereto included in the Form 10-K. Unless otherwise indicated, all balances within tables are in thousands, except per share amounts.

The Company completes its goodwill and indefinite life intangible asset impairment assessment annually in the fourth quarter, or more often if circumstances require. As a part of its impairment assessment, the Company first qualitatively assesses whether current events or changes in circumstances lead to a determination that it is more likely than not, defined as a likelihood of more than 50 percent, that the fair value of a reporting unit or indefinite life intangible asset is less than its carrying amount. If there is a qualitative determination that the fair value is more likely than not greater than the carrying value, the Company does not quantitatively test for impairment. If this qualitative assessment indicates a more likely than not potential that the asset may be impaired, the estimated fair value is calculated. If the estimated fair value is less than carrying value, an impairment charge is recorded. As of September 30, 2024, the Company reviewed its previous forecasts and assumptions based on its current projections, which are subject to various risks and uncertainties, including projected revenue, projected operational profit, terminal growth rates, and the cost of capital. The Company did not identify any triggering events during the three or nine months ended September 30, 2024 that would require an interim impairment assessment of goodwill or intangible assets. The Company’s assumptions about future conditions important to its assessment of potential impairment of its goodwill and indefinite life intangible assets are subject to uncertainty, and the Company will continue to monitor these conditions in future periods as new information becomes available, and will update its analysis accordingly.

Income Tax Disclosure [Abstract]
Income Taxes	12. Income Taxes The Company files income tax returns in various federal, state and local jurisdictions. Tax years from 2018 forward remain open for examination by Federal authorities. Tax years from 2017 forward remain open for all significant s tate and foreign authorities. The Company accounts for uncertain tax positions pursuant to ASC Topic 740, “Income Taxes.” As of September 30, 2024 and December 31, 2023, the liability for uncertain tax positions totaled approximately $ 0.2 million, which is included in “Other liabilities” on the Condensed Consolidated Balance Sheets. The Company recognizes accrued interest related to uncertain tax positions and penalties, if any, in income tax expense within the Condensed Consolidated Statements of Income. Certain of the Company’s undistributed earnings of our foreign subsidiaries are not permanently reinvested. Since foreign earnings have already been subject to United States income tax in 2017 as a result of the 2017 Tax Cuts and Jobs Act, the Company intends to repatriate foreign-held cash as needed. The Company records deferred income tax attributable to foreign withholding taxes that would become payable should it decide to repatriate cash held in our foreign operations. As of September 30, 2024 and December 31, 2023, the Company recorded deferred income taxes of approximately $ 0.9 million and $ 0.7 million, respectively, on the undistributed earnings of its foreign subsidiaries. Income tax expense was $ 1.6 million and $ 0.6 million for the three months ended September 30, 2024 and 2023, respectively, and $ 2.7 million and $ 1.6 million for the nine months ended September 30, 2024 and 2023, respectively. The effective income tax rate for the three months ended September 30, 2024 was 38.7 % compared with 13.6 % for the three months ended September 30, 2023, and the effective income tax rate for the nine months ended September 30, 2024 was 21.8 % compared with 13.4 % for the nine months ended September 30, 2023. The effective income tax rates for the three and nine months ended September 30, 2024 and 2023 differ from the United States federal statutory rate. The Company's effective rate is affected by certain other permanent differences, including state income taxes, non-deductible incentive stock-based compensation and differences in tax rates among jurisdictions in which it operates. Additionally, the Company received a tax indemnification payment of $ 0.5 million, related to a prior year acquisition, in the second quarter of 2024. The Organization for Economic Co-operation and Development/G20 Inclusive Framework on Base Erosion and Profit Shifting published the Pillar Two model rules designed to address the tax challenges arising from the digitalization of the global economy which introduces a 15 % global minimum corporate tax for companies with revenues above € 750 million calculated on a country-by-country basis. On February 1, 2023, the FASB indicated that it believes the minimum tax imposed under Pillar Two is an alternative minimum tax, and, accordingly, deferred tax assets and liabilities associated with the minimum tax would not be recognized or adjusted for the estimated future effects of the minimum tax but would be recognized in the period incurred. Aspects of Pillar Two legislation have been enacted in certain jurisdictions in which the Company operates effective for accounting periods commencing on or after January 1, 2024. However, based on the current revenue threshold, the Company is currently not subject to Pillar Two taxes.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	14. Commitments and Contingencies Asbestos cases The Company's subsidiary, Met-Pro Technologies LLC (“Met-Pro”), beginning in 2002, has been named in asbestos-related lawsuits filed against a large number of industrial companies including, in particular, those in the pump and fluid handling industries. In management’s opinion, the complaints typically have been vague, general and speculative, alleging that Met-Pro, along with the numerous other defendants, sold unidentified asbestos-containing products and engaged in other related actions which caused injuries (including death) and loss to the plaintiffs. Counsel has advised that more recent cases typically allege more serious claims of mesothelioma. The Company’s insurers have hired attorneys who, together with the Company, are vigorously defending these cases. Many cases have been dismissed after the plaintiff fails to produce evidence of exposure to Met-Pro’s products. In those cases, where evidence has been produced, the Company’s experience has been that the exposure levels are low and the Company’s position has been that its products were not a cause of death, injury or loss. The Company has been dismissed from or settled a large number of these cases. Cumulative settlement payments from 2002 through September 30, 2024 for cases involving asbestos-related claims were $ 7.0 million which together with all legal fees other than corporate counsel expenses have substantially been paid by the Company’s insurers. The average cost per settled claim, excluding legal fees, was approximately $ 33,000 . As of September 30, 2024 and December 31, 2023, the amount recorded within "Accrued expenses" on the Condensed Consolidated Balance Sheets was $ 0.2 million and zero , respectively, related to asbestos litigation. Based upon the most recent information available to the Company regarding such claims, there were a total of 343 cases pending against the Company as of September 30, 2024 with Illinois, New York, Pennsylvania and West Virginia having the largest number of cases, as compared with 313 cases that were pending as of December 31, 2023. During the nine months ended September 30, 2024, 136 new cases were filed against the Company, and the Company was dismissed from 71 cases and settled 35 cases. Most of the pending cases have not advanced beyond the early stages of discovery, although a number of cases are on schedules leading to or scheduled for trial. The Company believes that its insurance coverage is adequate for the cases currently pending against the Company and for the foreseeable future, assuming a continuation of the current volume, nature of cases and settlement amounts. However, the Company has no control over the number and nature of cases that are filed against it, nor as to the financial health of its insurers or their position as to coverage. The Company also presently believes that none of the pending cases will have a material adverse impact upon the Company’s results of operations, liquidity or financial condition. Other The Company is also a party to routine contract and employment-related litigation matters, warranty claims and routine audits of state and local tax returns arising in the ordinary course of its business. The final outcome and impact of open matters, and related claims and investigations that may be brought in the future, are subject to many variables, and cannot be predicted. The Company records accruals for estimated losses relating to claims and lawsuits when available information indicates that a loss is probable and the amount of the loss, or range of loss, can be reasonably estimated. The Company expenses legal costs as they are incurred. The Company is not aware of any pending claims or assessments, other than as described above, which may have a material adverse impact on its liquidity, financial position, results of operations, or cash flows.

Acquisitions and Joint Ventures	15. Acquisitions EnviroCare International LLC On July 29, 2024, the Company completed its acquisition of EnviroCare International LLC (“EnviroCare"), based in American Canyon, California. EnviroCare is an international designer and provider of industrial exhaust air contamination treatment and control systems, solutions and services across a wide range of industrial and municipal applications. The estimated purchase price was approximately $ 13.0 million consisting of $ 15.7 million paid at closing and a seller promissory note of $ 1.7 million, partially offset by an estimated working capital adjustment of $ 4.4 million. The acquisition was financed using a combination of cash on the balance sheet and borrowings under the Company’s existing Credit Facility. The following table summarizes the preliminary fair values of the assets acquired and liabilities assumed at the date of closing. (in thousands) Current assets (including cash of $ 374 and accounts receivable of $ 405 ) $ 3,111 Property and equipment 17 Intangible - finite life 7,250 Goodwill 7,579 Total assets acquired 17,957 Current liabilities assumed ( 4,949 ) Net assets acquired $ 13,008 The Company acquired technology, customer lists and tradename intangible assets valued at $ 0.8 million, $ 0.8 million and $ 5.7 million, respectively. These assets were determined to have useful lives of 7 , 10 and 10 years, respectively. During each of the three and nine months ended September 30, 2024, EnviroCare accounted for $ 2.4 million in revenue and $ 0.3 million of net income in the Company's results. Kemco Systems Co., LLC On August 23, 2023, the Company acquired 100 % of the equity interests of Kemco for $ 24.0 million in cash, which was financed with a draw on the Company’s revolving credit facility. During the three months ended March 31, 2024, the Company received $ 0.4 million from the former owners of Kemco as a working capital adjustment, reducing the purchase price to $ 23.6 million. As additional consideration, the former owners of Kemco are entitled to earnout payments up to $ 4.0 million based upon specified financial results through August 31, 2026, of which $ 1.7 million was paid during the second quarter of 2024. Based on projections at the acquisition date, the Company estimated the fair value of the earnout to be $ 2.2 million, which was subsequently adjusted to $ 2.7 million in the first quarter of 2024.

Subsequent Events [Abstract]
Subsequent Events	17. Subsequent Events On October 29, 2024, the Company announced that it has entered into an Agreement and Plan of Merger (the “Merger Agreement”) to acquire for cash all of the shares of Profire Energy, Inc. (Nasdaq: PFIE) ("Profire"), with the transaction expected to be completed in first quarter of 2025. Profire is a leader in burner management technology and combustion control systems that provide mission-critical combustion automation and control solutions and services to improve environmental efficiency, safety and reliability for industrial thermal applications globally. Profire is headquartered in Lindon, Utah and has locations in Texas, Pennsylvania, Colorado, Ohio and Alberta, Canada. Under the terms of the Merger Agreement, a subsidiary of the Company will commence a tender offer to acquire all issued and outstanding shares of Profire’s common stock at a price of $2.55 per share, in cash, without interest and subject to applicable withholding tax. The tender offer will initially remain open for 20 business days from the date of commencement of the tender offer, subject to extension under certain circumstances. The transaction implies an equity value of approximately $125 million and a total enterprise value for Profire of approximately $108 million. The tender offer is subject to customary closing conditions, including that at least a majority of the outstanding shares of Profire’s common stock are tendered and not withdrawn in the tender offer and the expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. Upon completion of the transaction, Profire will become a wholly-owned subsidiary of CECO and shares of Profire’s common stock will no longer be listed on any public market. The impact of this pending transaction is not included in the Company's financial results for the three or nine months ended September 30, 2024 and is not expected to impact financial results for the fourth quarter of 2024. On October 2, 2024, the Company completed the acquisition of WK Germany KG, GmbH and WK Asia-Pacific Pte. Ltd. (collectively, "WK Group"). WK Group, with locations in Germany, Singapore, China and India, designs and engineers a broad range of cutting-edge technical equipment and systems for process and environmental and surface technology applications, as well as innovative sustainable solutions. This acquisition advances the Company's footprint and capabilities within the industrial processing solutions segment. The purchase price paid at closing was € 10.8 million, inclusive of net cash at close, (approximately $ 11.9 million), financed using borrowings under the Company's existing Credit Facility. There is also an earnout arrangement based on the achievement of specified financial targets through September 30, 2025, as defined in the purchase agreement. The impact of this acquisition is not included in the Company's results for the three or nine months ended September 30, 2024. The initial accounting for the acquisition was not complete at the time the financial statements were issued due to the timing of the acquisition and filing of this Quarterly Report on Form 10-Q. As a result, complete disclosures as required under ASC 805, Business Combinations cannot be made at this time. On October 7, 2024, the Company entered into the Third Amended and Restated Credit Agreement (the “Amended Credit Agreement”), among the Company, its subsidiaries from time to time party thereto, the lenders from time to time party thereto (the “Lenders”) and Bank of America, N.A., as administrative agent (the “Agent”), which amended and restated in its entirety the Company’s Second Amended and Restated Credit Agreement, dated as of June 11, 2019, among the Company, its subsidiaries from time to time party thereto, the lenders from time to time party thereto and the Agent. The Amended Credit Agreement provides for a senior secured revolving credit facility in an initial aggregate principal amount of up to $ 400.0 million (the “Amended Credit Facility”). At the Company’s option, the Company may increase the aggregate principal amount of the Amended Credit Facility from time to time by an additional aggregate principal amount of up to (a) $ 125.0 million plus (b) such additional amount, if any, as would not cause the Consolidated Secured Net Leverage Ratio (as defined in the Amended Credit Agreement) to exceed 3.00 to 1.00 after giving pro forma effect to such increased amount, in additional revolving credit and/or one or more tranches of term loans, subject to certain conditions, including the consent of the Agent and any increasing or additional lenders . The Amended Credit Facility will mature on October 7, 2029 . The Credit Facility will accrue interest (a) with respect to base rate loans, at an annual rate equal to an applicable rate of between 0.75 % and 2.25 % (fluctuating based on the Company’s Consolidated Net Leverage Ratio), plus a rate equal to the highest of (1) the Agent’s prime rate, (2) the federal funds rate plus one-half of 1.00 %, (3) Daily Simple SOFR (as defined in the Credit Agreement) plus 1.00 % and (4) 1.00 %, (b) for all other loans, at an annual rate equal to an applicable rate of between 1.75 % and 3.25 % (fluctuating based on the Company’s Consolidated Net Leverage Ratio), plus a rate determined based on the denominated currency and, as applicable pursuant to the Amended Credit Agreement, whether the Company has elected for interest on such loans to accrue at a daily rate or a term rate: (a) for term rate loans, if denominated (1) in U.S. Dollars, Term SOFR (as defined in the Amended Credit Agreement inclusive of a 0.10 % per annum adjustment), (2) in euros, EURIBOR, (3) in Canadian dollars, the Term CORRA Rate (as defined in the Credit Agreement) plus 0.29547 % for a one-month interest period and 0.32138 % for a three-month interest period or (4) in a currency other than (1)-(3), the rate per annum as designated with respect to such currency at the time such currency was approved by the Agent and the other Lenders or, if such rate is unavailable on any date of determination for any reason, a comparable or successor rate approved by the Agent, and (b) for daily rate loans, if denominated (1) in U.S. dollars, Daily Simple SOFR (as defined in the Credit Agreement inclusive of a 0.10 % per annum adjustment), (2) in pounds sterling, a rate per annum equal to SONIA (as defined in the Credit Agreement) plus 0.0326 % per annum or (3) in a currency other than (1) or (2), the rate per annum as designated with respect to such currency at the time such currency was approved by the Agent and the other Lenders or, if such rate is unavailable on any date of determination for any reason, a comparable or successor rate approved by the Agent. The Amended Credit Facility contains covenants and representations and warranties that are usual and customary for similar transactions. With respect to financial covenants, the Company is required to maintain a Consolidated Net Leverage Ratio not greater than 4.00 to 1.00 and a Consolidated Secured Net Leverage Ratio (as defined in the Credit Agreement) not greater than 3.00 to 1.00 , in each case as of the last day of each fiscal quarter of the Company. At the election of the Company and subject to certain restrictions contained in the Amended Credit Agreement, following the occurrence of a Permitted Acquisition (as defined in the Credit Agreement) involving aggregate consideration of $ 15.0 million or more, such maximum Consolidated Net Leverage Ratio and Consolidated Secured Net Leverage Ratio may be increased to 4.50 to 1.00 and 3.50 to 1.00 , respectively, for the fiscal quarter in which such Permitted Acquisition is consummated and the subsequent three fiscal quarters of the Company. The Company is also required to maintain a Consolidated Fixed Charge Coverage Ratio (as defined in the Amended Credit Agreement) as of the last day of each fiscal quarter of the Company of not less than 1.25 to 1.00 .
