High Voltage Heaters (HVH) High efficient heating system for your vehicle
Our High Voltage Heater (HVH) is the ideal heating system for plugin hybrids and electric vehicles. It converts DC electric power into heat with practically no losses. Depending on the application and requirements, the 5, 7, 10 or 12 kW variant can be selected, which provide different heating outputs.
Powerful 5/7/10/12 kW heating performance and wide voltage range up to 880 V independent of coolant temperature Better ranges with the same battery capacity and optimum climate comfort
Innovative Layer technology for extremely fast heat up Highest efficiency through quick and direct heat transfer Seamless and exact controllability with no inrush currents Reliable safety concept with redundant controls Certified for automotive requirements with ECE R10 and ECE R122 type approval Technical specifications HVH 50 Gen 1.5
