NARSA Members IN ACTION IN ACTION G&M recently completed manufacture of this large oil cooler for a piece of industrial equipment. It was a challenging assembly process to ensure such a large unit remained square during the welding work. The 10mm tube plate and the long spiral wound oil tubes certainly tested our team's abilities, but the end result is impressive. After testing, GM's technicians applied several coats of specialized protective coatings to ensure this cooler will withstand the rigors of operating in a marine environment for many years to come. 24 | THE COOLING JOURNAL | January/February 2024
