L&M Radiator

What L&M Radiator does

L&M Radiator, Inc. is a US-based manufacturer of heavy-duty cooling and heat transfer solutions, founded in 1957 in Hibbing, Minnesota, and operating as a wholly-owned subsidiary of Wabtec Corporation (NYSE: WAB) since 2016. The company designs and builds field-repairable heat exchangers, radiators, charge air coolers, oil coolers, and tube-and-shell coolers under its proprietary MESABI brand, with the core technology centered on a flexible core architecture using removable copper grommeted tubes sealed with proprietary grommets that enable in-field tube replacement without removing the radiator from the equipment. Recent product extensions include the MESABI Thermal Management System (MTMS) for electric mining trucks and hydrogen fuel cell vehicles, as well as the Cube compact cooling system and Mesabi System Protector accessories.

The company's commercial model is built on direct enterprise field sales backed by a global network of regional sales representatives covering North America, South America, Europe, Asia, Oceania, Africa, the Middle East, and Russia, supplemented by wholly-owned subsidiaries in Australia and Chile. Pricing is quote-based (RFQ-driven) and revenue derives from three streams: sale of MESABI cooling units to OEMs (Komatsu specifies MESABI as standard equipment) and end users, sale of replacement parts shipped within 24-72 hours to a large installed base, and custom heat transfer engineering for specialized applications. Customer segments span mining, oil and gas, railway, construction and aggregates, power generation, agriculture, and emerging electric/hydrogen heavy equipment, with named enterprise customers including Baffinland Iron Mines, Rio Tinto/Freeport McMoran, Australian Railways, Pikes Peak Cog Railway, Loram Rail Grinders, and Santee Cooper. The company holds ISO 9001:2000 certification and maintains manufacturing operations in Hibbing, Minnesota and Yankton, South Dakota, employing 101-250 people globally.
