"The QL air heater extracts heat from the engine's cooling system, which would otherwise be wasted, and transfers it into the cabin. A fan circulates air th-rough a heat exchanger, which is heated by the engine cooling system. The air heater makes it possible to make use of the engine closed-circuit cooling system without additional water piping and radiators.
Transferring the heat through a heat exchanger allows the heated air to be quickly sent to where it's needed most. For example to defrost/demist the windshield, or warm up the cabin. Four outlets are supplied that can be connec-ted to air hoses. The standard outlets are 55 mm diameter. The airflow can be set at three different speeds. The QL air heater is highly efficient and can be in-stalled vertically or horizontally."
