Forced Circulation Engine Heating Systems
HOTSTART offers complete circulating heating systems for engines ranging in sizes from 10 L to the largest displacement currently in production. These systems are engineered and designed specifically for installation on a generator, compressor package, marine engine, or locomotive. HOTSTART offers circulating systems for lube oil heating, coolant heating and diesel fuel heating. Combination systems are also available that heat and circulate coolant and oil in one pre-assembled unit.
Coolant-Only Circulating Heating Systems
These systems are designed to heat and circulate coolant throughout the engine's cooling system to efficiently maintain an engine at optimum starting temperatures. Maintaining jacket water temperatures ensures easy starting, reduces harmful emissions at start-up and allows engines to go to full power without needless idling.

Oil-Only Circulating Heater Systems
HOTSTART's lube oil systems heat and circulate engine lube oil to efficiently maintain oil viscosity and minimize condensation during shut-down and layover periods. Warm lube oil greatly reduces oil viscosity, thus increasing lubrication to the engine at start-up. These systems are available for engines with oil capacities ranging from 95 L to 5341 L.
|HOTSTART Heater||Oil Capacity*||Heat Output|
|OSE Model||flow requirement up to 11GPM Hazardous Location||1.5-2.5 kW|
|OSX Model||flow requirement up to 11GPM Hazardous Location
|OSM Model||up to 350 L Weathertight||1-3 kW|
|OMM Model||up to 666 L Weathertight||3-6 kW|
|OLM Model||up to 1332 L Weathertight||9-12 kW|
|OGM Model||up to 5341 L Weathertight||24-48 kW|
|OLA Model||up to 2700 L Hazardous Location (ATEX)||2.5-24 kW|
|OLE Model||up to 2700 L Hazardous Location||2.5-24 kW|
Additional oil heaters available for 12-24 kW heat output. Contact HOTSTART for more information.
Combination Coolant/Oil Circulating Heating Systems
HOTSTART's line of coolant/lube oil combination heating systems combines the benefits of coolant heating and oil heating into one pre-wired, pre-assembled dual heating package. Circulating heated coolant and lube oil throughout the engine ensures optimum starting temperatures and oil viscosity while reducing condensation.
