Webasto’s Thermo Top Evo Coolant Heater operates from diesel fuel drawn from the vehicle’s primary fuel tank while the engine is off, reducing idling time, warming engines so they start easier and helping reduce the strain on emissions control devices. The compact unit has an 8,600-17,200 Btu/h (2.5–5.0 kW) range and operates at a high maximum combustion air temperature engineered to allow it to be mounted in more locations within the engine compartment. Its coolant inlet and outlet ports can rotate up to 180 degrees, offering greater flexibility for routing coolant lines, and it comes with a long fuel line, a universal controller harness and a mounting bracket. The unit can be controlled manually or programmed to turn on in advance via Webasto’s SmarTemp Control fx 2.0, and fault codes can be read at the controller without ancillary equipment or software. Its DP 42 fuel pump uses half-stroke technology that facilitates quiet operation.
