Webasto North America, Fenton, Mich., introduced its new Thermo Top Evo coolant heater, which operates directly from diesel fuel drawn from the vehicle’s primary fuel tank.

The Thermo Top Evo is more flexible to install, more intuitive to diagnose and features a quieter heater and fuel delivery system. With its efficient 8,600–17,200 BTU/h (2.5–5.0 kW) range and ultra-low power consumption, the Thermo Top Evo pre-heats a wide range of vehicle types, from light-duty commercial vehicles to heavy-duty trucks. Plus, its coolant inlet and outlet ports at the top of the heater can rotate up to 180 degrees, offering greater flexibility for routing coolant lines.

The unit comes with a longer fuel line, universal controller harness and mounting bracket, and operates at a higher maximum combustion air temperature, so it can be mounted in more locations within the engine compartment.

The Thermo Top Evo also gives users the ability to read simple fault codes at the controller without the need for ancillary equipment or software. This feature enables the driver to identify the specific fault category while on the road. The Thermo Top Evo can be controlled manually or programmed to turn on in advance via Webasto’s SmarTemp Control fx 2.0 so the engine is pre-warmed when the driver arrives.
