Exchanger Industries was founded in Calgary, Alberta by Howard Thom in 1961 as Exchanger Sales and Services to manufacture tubular heat exchangers. By 1964 the company was also manufacturing air-cooled heat exchangers, sulfur condensers and waste heat boilers, which still remain core products to the present day.
Exchanger Industries specializes in large-scale fabrication and solving complex design problems, as well as offering alternative design solutions which lower the total life-cycle cost of projects. In particular EIL units are found in the petrochemical, industrial, and clean power generation sectors. Over the years EIL has introduced a number of new applications and developments including new baffle designs and coatings.
