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. Circulating warm lube oil greatly reduces oil viscosity, thus increasing lubrication to the engine at start-up. Maintaining consistent oil temperatures prevents condensation which in turn extends the life of the engine’s oil. This versatile heating system is available for engines with oil capacities ranging from 25 to 500 gallons (96-1892 liters). All OER models are explosion resistant in order to function in hazardous locations ensuring safe, electrical operation. All OER lube oil heating systems are CSA approved.
