Autoterm Air 4D heater is an independent, diesel powered heating systems that can be easily and conveniently installed in your campervan. The heater is supplied with fresh air from outside or well ventilated air from the room, which is taken through an air intake pipe to the internal combustion chamber. The received air is then mixed with the fuel, which is delivered through a metering fuel pump, and the air-fuel mixture is formed. This mixture is then ignited by a glow plug, which initiates the burning process to heat up the heat exchanger. Air is then drawn from the air inlet with a fan and passed through heat exchangers and the radiator fins. Finally, the heated air is pushed through the hot air outlet.
