SAFETY & COMFORT – AIR HEATER
AIR HEATER
The 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 through a heat exchanger.
The air heater makes it possible to make use of the engine
closed-circuit cooling system without additional water pipes
and radiators.
Four outlets are supplied that can be connected with air hoses. The
standard outlets are 55 mm diameter. The airflow can be set at three
different speeds.
The air heater is highly efficient and can be installed vertically or
horizontally. Its compactness makes it easy to install almost anywhere.
The selection of materials; stainless steel for the casing and copper/
brass for the heat exchanger, ensures long service in a harsh onboard
atmosphere.
The air heater comes in two sizes; 5 and 10 kW. Available for 12 V or
24 V supply, it consumes very little power. Its low noise level is another
advantage. The air heater can be installed above the engine and any air
trapped in the coolant can be released through a separate bleed valve.
Optional extras include air hoses, hose connections and various types
of air valves.
