Hotstart OCSM Oil Coolant Heating System

Ensure reliable starts and reduce engine wear with the OCSM Engine Preheater System — ideal for marine, machinery, and backup power generation applications.

The OCSM heats and circulates engine lube oil throughout the sump and external piping, while also preheating and circulating engine coolant. This dual-function system makes cold starts easier and protects your engine from damage caused by low-temperature operation.

Featuring built-in controls for automatic heater operation, the OCSM eliminates the need for extra control components. Its compact, versatile design includes an integrated coolant-to-oil heat exchanger, delivering maximum heat output in minimal space — perfect for a wide range of installations.
