Eberspaecher’s Hydronic S3 Economy (5 kilowatt) engine pre-heater is a compact system designed for flexible installation in work truck, day-cab, off-highway, construction and municipal vehicle applications.
The Hydronic S3 Economy is CARB-approved and designed for simple operation with step-less heating power control. The coolant heater works with common types of fuel, according to Eberspaecher. The pre-heater features an encapsulated fan motor with separated cold and hot components to improve longevity.
A high IP rating also secures the unit from the ingress of water during high-pressure or steam jet cleaning. Water spigots are fully rotatable and are replaceable, ensuring a simpler and quicker fitting in a range of installation positions. Optimized brackets allow the pre-heater to be mounted in the smallest possible space.
The water heater features a CAN-bus interface. Workshop staff can analyze the operating condition of the pre-heater with an EasyScan diagnostic and service tool.
