About
R.W. Fernstrum & Company was founded in 1945 and is based in Menominee, Michigan. In 1943 Robert W. Fernstrum, then working with Gray Marine, was assigned to solve cooling problems on the engines of U.S. Navy landing craft and engineered the first rectangular tube keel cooler. He received a patent for the design in 1945 and launched the company.
The business remains family owned and operated, with the fourth generation of the family now working in it. It is an ISO 9001:2015 certified company.
Fernstrum has partnerships with WEKA Marine to manufacture and sell copper-nickel boxcoolers for North and South America and with Omega Thermo Products for laser plate heat exchangers.
