KEEL COOLER

R.W. Fernstrum & Company, a global leader in engineering and manufacturing keel cooling technologies, was founded in 1945 when our founder Robert W. Fernstrum patented the first rectangular tube keel cooler with an angled header for the United States Army and Navy. During World War II, the U.S. Navy encountered engine cooling problems with their landing craft and required a new closed-circuit cooling system. At the time, Mr. Fernstrum was working with Gray Marine, the engine manufacturer powering the landing craft. The Navy approached Gray Marine regarding the problem and tasked Robert with the responsibility of creating a closed circuit cooling system. After intense research, Mr. Fernstrum developed the basic keel cooler design that is used today... The GRIDCOOLER® Keel Cooler has evolved over the years into a line of keel coolers that offers nearly limitless variations to fit a particular application. Our commitment to bringing the latest in cooling technologies to the marine..
