Forced Circulation – Dual Fluid
HOTSTART's Forced Circulation Dual Fluid Heaters feature integrated pumps to move heated coolant throughout the engine’s water jacket while simultaneously moving heated oil throughout the oil sump. Continuous circulation means heated coolant and oil is kept at a consistent temperature, ensuring both the components and lubrication oil are maintained at ideal conditions for engine start. HOTSTART Forced Circulation Heaters are available in weathertight or hazardous location models for a wide range of installation environments.
