Sporlan Cold War

Cold War (Whether it’s Air Conditioning or Refrigeration) is a series of short and pointed articles on current topics of interest in the HVACR industry. The idea was conceived by Garth Denison. Garth retired from DuPont Canada in 2002 as Senior Technical Consultant, Fluoroproducts Division, and then accepted a position with Sporlan Canada as Senior Application Engineer. Garth was active in RSES, and served as a former International President.

After Garth retired, I assumed the role of writing Cold War articles until I left Sporlan to take a position at Tecumseh Products in Ann Arbor, MI.
