Our legacy as one of the world's leading providers of cooling and heat transfer solutions began in 1957. L&M Radiator, Inc. acquired the rights to the individual replaceable cooling tube radiator concept originally developed by the British in WWII. We brought this concept to the Minnesota Mesabi Iron Range. With rapid acceptance of the "MESABI® Radiator" in the mining industry, the concept skyrocketed into worldwide popularity as both an OEM and aftermarket product for mobile and stationary heavy-duty equipment. Thus, the generation of MESABI® products.

What was important then is just as important now. Today, L&M Radiator, Inc. has evolved into the premier global supplier of precision-engineered OEM cooling and heat transfer solutions. MESABI® Heat Exchangers are the world standard for heat transfer reliability.
