The 800V air heater from Eberspaecher installs directly into a truck's air-conditioning system and provides multi-zone function for greater temperature control. Able to separately control up to four zones in the truck cab, the heater uses PTC technology close to the passenger. It also self regulates to avoid overheating, and features a power range of 3-8 kW and can accommodate 400- and 800-volt systems. This heater will be available in North America starting in 2028.
