Diesel Coolant Heater From Espar

Hydronic Espar Heater series (Gasoline/ Diesel) offers affordable preheating of engine, fuel, and hydraulic systems as well as supplemental cab heating without idling the vehicle. Integrated into the engine’s coolant system, coolant heaters circulate the engine coolant over a heat exchanger to warm the engine and related components such as motor oil, fuel injectors, cylinders, and engine gaskets. This eases the strain on the starter when the vehicle is started.
