Although the company continued to experience a challenging operating environment due to weak economic conditions, gross margins increased year over year as a result of reduced costs and a shift in product mix to higher margin products.

In further response to the economic environment, the Company has continued to reduce overhead as well as selling and administrative expenses. On a comparative basis, excluding certain expenses from companies acquired in 2008, selling and administrative expenses were reduced by $1.6 million or 18.7% for the three months ended September 30, 2009 and $2.9 million or 12.5% for the nine month period ended September 30, 2009.

“Our third quarter performance did not meet our expectations as the weak economic environment continued to negatively affect our financial results,” said Phillip DeZwirek, CECO’s Chairman and CEO. “Notwithstanding, we have already seen some positive signs in the fourth quarter that coupled with the cost and operating initiatives that were implemented throughout the year, should translate into better performance for the rest of the year and into 2010.”

President and Chief Operating Officer, Richard Blum, stated, “The third quarter was a challenging period for the Company and the industry as a whole. Our financial results continued to be affected by the weak economy and the reduced demand from our customers. However, September showed improving results due to increasing revenues as well as cost cutting initiatives we implemented throughout the year.”

CECO will host a conference call on Monday, November 9, 2009 at 8:30 a.m. EST to review its financial results for the quarter. Conferencing details are as follows:

CECO is providing the non-GAAP historical financial measures presented above as the Company believes that these figures are helpful in allowing individuals to better assess the ongoing nature of CECO’s core operations. A “non-GAAP financial measure” is a numerical measure of a company’s historical financial performance that excludes amounts that are included in the most directly comparable measure calculated and presented in the GAAP statement of operations.

Exhibit 99.1

Non-GAAP comparative selling and administrative expenses as we present them in the financial data included in this press release have been adjusted to exclude the effects of expenses related to recent acquisitions that were not comparably present in prior periods. Flextor, Inc. was acquired in August 2008 and Fisher-Klosterman Inc. (FKI) was acquired in March 2008. Management believes that these non-GAAP financial measures excluding these items better reflect its cost reduction performance as these non-GAAP figures exclude the effects of acquired selling and administrative expenses. Management believes that these items are not necessarily representative of underlying trends in the Company’s performance and their exclusion provides individuals with additional information to compare the Company’s results over multiple periods. We expect our financial statements to continue to be affected by Flextor and FKI expenses excluded in the non-GAAP adjustments described above, and exclusion of these items from our non-GAAP financial measures should not be construed as an inference that all such costs are unusual or infrequent.

In accordance with the requirements of Regulation G issued by the Securities and Exchange Commission, the tables above present the most directly comparable GAAP financial measure and reconcile non-GAAP comparative selling and administrative expenses to the comparable GAAP measures.

This press release may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements may be identified by words such as “believe,” “anticipate,” “intend,” “expect,” “feel,” “may,” “could,” “would,” “will,” “should,” “plan” or similar statements. All forward-looking statements are subject to certain risks, uncertainties and assumptions. These risks and uncertainties, which are more fully described in CECO’s Annual and Quarterly Reports filed with the Securities and Exchange Commission, include changes in economic conditions and changes in market conditions in the industries in which the Company operates. Should one or more of these risks or uncertainties materialize, or should the assumptions prove incorrect, actual results may vary in material aspects from those currently anticipated.
