Designs available to meet all current and past emission requirements and standards.


From the simple to the complex, including remote power units with fans and drives.

BOSS™ Radiator

The BOSS™ (Brass Off Shore Service) is designed for equipment working in corrosive environments. It features brass finning brazed to brass tubes. Mild steel framework is coated for offshore service; stainless steel framework optional.

V-Tube Core™

Tube Configuration Options

The V-tube core is designed for work-sites where cores may be subject to external clogging due to dirt and debris. Tubes are configured to create open passages. Finning is V-shaped to resist material hang-up. Debris slides past tubes and through passages. Debris too large for passages is easily removed with high-pressure water or air.


The L&M Radiator Warranty consists of the L&M Radiator General Warranty and the L&M Product Specific Warranty.
