L&M Radiator’s 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 and 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.

L&M Radiator, Inc., headquartered in Hibbing, Minnesota, is a global company that specializes in designing, manufacturing, and distributing MESABI industrial radiators and heat exchangers for heavy industrial applications. L&M has been serving industries around the globe for over 65 years, and have recently been acquired by Wabtec Corporation, a company in the making for over 150 years and 27,000 employees strong. With a dedicated focus on delivering high-quality, engineered products, L&M has joined the Wabtec family to continue producing the world’s greatest heat exchangers on the market while driving innovation and changing the way the world moves.


L&M takes great pride in our employees striving for a people-first culture. We treat our employees like family. Quality minded, driven, flexible, and adaptability are strong qualities we look for in people that want to be a part of the Mesabi Difference. With our state-of-the-art facility and the latest technology, we are always looking for continuous improvement processes to lead the way in the heating and cooling industry. We train our people to work smarter, so they can have opportunities to be creative, expand the impossible, and use new ways to stay engaged and be a part of the future as one Wabtec.
