Thermo AC/DC

This heater has the wattage

For optimum thermal management in hybrid, electric, hydrogen and trolleybuses Valeo offers the Thermo AC/DC all-electric heater.
The independently operated heater with direct (600 VDC) or alternating current (400 VAC) is our answer to the drives of the future:
It is 100% emission-free, i.e. no unpleasant odours from exhaust fumes and no noise. With a heat output of 7, 13 or 20 kW and efficiency factor of 98% the heater is suitable even for outside temperatures up to -40 degrees Celsius. Reliable operation is ensured by a proven and tested temperature sensor in the device.
