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