New MESABI® System Protector™ Tube and Shell Cooler provides a dependable safeguard for systems under constant operation. • Protects transmission, brake and hydraulic systems from cross-contaminated fluids and the downtime and repairs that can follow • Alerts operator to any leaking • Has field-repairable features • Protects the environment Like all Mesabi Heat Exchangers, System Protector coolers have individual cooling tubes held in header plates with flexible rubber seals. Two seals at the end of each copper tube absorb thermal and mechanical stresses. A collection chamber between the seals in each header isolates dissimilar fluids passing through the heat exchanger, preventing cross-contamination. A site gauge or optional electronic sensor alerts operator to leaking fluid. System Protector coolers can be made in a variety of configurations of length and diameter for liquid and air heat exchange required by mobile and in-plant equipment. DOWNLOAD HIGH RES TIF (9.8mb Zip)		L&M Radiator announces a new high efficiency charge air cooler that uses the unique design feature of all MESABI heat exchangers – individual cooling tubes held in headers with shock-absorbing rubber seals. The all aluminum cooler is comprised of a single row of multi-ported cooling tubes that provide maximum internal and external area for heat transfer. Damaged tubes can be replaced using a simple hand tool. The seal between tube and header is held captive in the header; once a tube is inserted, a seal is created to withstand and exceed charge air cooling pressures. Because MESABI charge air coolers can be continually returned to 100% cooling capacity, they will outlast the equipment in which they are installed. MESABI coolers are easily cleaned with high pressure air or water. Coolers are for all charge air cooling and can be designed to meet engine manufacturer specifications.

L&M Radiator, Inc. has recently updated it's Mesabi® product line literature to include the company's latest heat exchanger introductions. All Mesabi products feature individual cooling tubes held in headers with flexible rubber seals. The seals absorb off-road shock and thermal expansion that can crack rigid soldered seams. The seals also allow damaged tubes to be removed and replaced in the field - often without removing the heat exchanger from the equipment. Products with the Mesabi design feature described in the literature are engine radiators, complete engine cooling packages, Mesabi retrofit replacement radiators for Caterpiller® folded cores, oil-to-air coolers, tube & shell coolers, charge air coolers and System Protector™ coolers.
