Eberspaecher's Coolant Heater is a compact and powerful alternative to PTC technology, according to the company. It features a thick film element (TFE), which applies to a metal plate through a screen-printing process, providing a high heat output with a smaller installation footprint. The 800-volt system achieves up to 12 kW of output and delivers enough output even at 400 volts. For added safety, the coolant heater features multiple sensors and an independently operating second shutdown path. The heater works for passenger cars and trucks, and will begin production in 2027.
