About

Hamon is a worldwide group of companies, headquartered in Belgium, that began business in the early years of the 20th century. While quite active in Europe, it did not enter the US until (in the late 60's) it licensed Research-Cottrell, Inc. to use Hamon's natural draft cooling tower technology in the US market. This relationship continued until 1983 when Hamon Cooling Towers was established as a US-based Hamon entity. Finally, in 1998, Hamon acquired certain assets (but no liabilities) including technology, names and trademarks of Research-Cottrell and Custodis from Air & Water Technologies bringing it largely to its present form in the US.

Nowadays, Hamon in the United States is comprised of 6 operating companies (click the headings to go to the company pages):
