CECO has expanded its portfolio over time through acquisitions across industrial air, industrial water, and combustion and safety solutions.
In 2015, CECO acquired Dallas-based PMFG, Inc. in a deal valued at about $150 million. Local business reporting later linked this acquisition period to CECOâÂÂs shift of its headquarters presence from the Cincinnati area to the Dallas region.

Under the terms of the agreement, Thermon shareholders will be able to elect to receive a combination of cash and CECO stock, all-cash consideration, or all-stock consideration, with CECO shareholders expected to own a majority of the combined company following closing. The acquisition is designed to broaden CECOâÂÂs portfolio by adding ThermonâÂÂs thermal solutions capabilities, including heat tracing and temperature management systems.
