The air heater provides defrost power with radial fans and three power steps. It transfers the surplus of heat coming from the engine to defrost as well as to heat the cabin. The heater is equipped with a radial fan offering three power steps and with four 60 mm hose brackets for the warm air distribution.

The Isotherm 10 kilowatt Air Heater connects to engine cooling water auxiliary output and uses engine heat to heat a  cabin and/or as a windshield defroster.   The Air Heat Exchanger transfers the surplus heat coming from the engine to heat the cabin.  It has a radial fan with three power steps and control switch.  The Isotherm Air Heater is equipped with four 60 mm hose brackets for the warm air distribution and two 90 mm hose connections for return air (hoses not included).
