A HALF CENTURY OF HEAT TRANSFER RELIABILITY
The British first developed the idea of individually replaceable cooling tubes held in headers with rubber seals during WWII desert tank warfare. The concept had these advantages:
- The flexible seals would allow damaged tubes to be removed and replaced even under combat conditions.
- The seals would absorb vibration pounding and thermal shock that would cause conventional radiators to leak.
Following WWII, Rolls-Royce motor cars and commercial vehicles were equipped with these radiators. In the early ‘50s, the radiator core first appeared on haul trucks in Canadian ore mines in Labrador.
In 1957, L&M Radiator acquired the rights to the concept and brought the radiator to the Minnesota Mesabi Iron Range. With rapid acceptance of the “MESABI® Radiator” in the mining industry, the concept grew in popularity worldwide as both an OEM and aftermarket product for all mobile and stationary heavy-duty equipment.
Today, the MESABI® replaceable tube concept, first developed for engine cooling, has been applied by L&M Radiator to all types of heavy-duty equipment heat transfer. MESABI® heat exchangers are the world standard for heat transfer reliability.
