A coolant heater warms the engine's coolant independent of a running engine, preheating the block for easier cold starts in low temperatures and feeding warm coolant through the vehicle's existing heater core to warm the cab -- all without idling.
VMACS carries genuine Webasto Thermo Pro and Thermo Top coolant heater kits, sized from 9.1kW up to 15kW output for machinery and vehicles with larger cooling systems. Kits include the heater, wiring harness, fuel system components and, where applicable, an enclosure box, with full Webasto-backed warranty support through VMACS as an Authorized North American Distributor.
