The 800 V High Voltage Heater (HVH) from Webasto is ideal for commercial electric vehicles such as trucks, busses as well as construction and agricultural machinery. It converts DC power into heat with practically no losses. This also contributes to sustainability. The innovative technology of Webasto works with an extremely thin heating layer that is firmly bonded onto the heat exchanger, and a large contact area for heating the coolant. The HVH therefore achieves extremely fast heat-up times, precise control, and the highest efficiency.
