While the TSM brand launched in 2012, our roots can be traced back to 1915 when G&O Manufacturing opened their doors in New Haven, CT. A lot has changed since then but our commitment to quality and service has never wavered.


An extensive catalog of quality parts also requires fast shipping. Our national network of dealers and branches ensures personalized service with an emphasis on turnaround times. Click here to find the location closest to you.


We don’t just sell heat exchangers - we research, develop, and manufacture them at plants located across the United States and Mexico. While we don’t build every item we sell, the insights gained from our own production cycles ensure every part we sell is designed TSM quality tough.
