Espar Hydronic coolant heater series offers affordable operation in preheating of engines, fuel, and hydraulic systems. The Hydronic heater also offers supplemental cab heating without idling the vehicle. The units operate similar to hot water furnaces, by utilizing the vehicle’s own fuel and power supply to produce heat. The glycol heater then circulates coolant via a built in pump to transfer the heat to the engine block. Common applications include: trucks, off-highway equipment, boats, and buses. These units are easily installed and do not require electrical plug-ins. Models include: Espar D5, Espar D6L, Espar m-ii, Espar S3
