Introduction
The main parts of both the MV Airo 2 and Airo 5 air heaters (hereinafter
referred to as ‘the heater’) are a small fuel furnace controlled by a single-chip
micro-processor. Its furnace body (the heat exchanger) is located in the hood
shaped case, which serves as an independent air passage. Cold air is drawn
into the air passage by the fan, heated by the heat exchanger and blown out
as hot air.
An example of how the heater operates is shown in Figure I. Hot air is
supplied by the heater to the driver’s cab and/or passenger’s compartment
independently from the engine. The same theory applies to campervans,
cranes, marine vessels etc.
The heater is fully automatically controlled. It features a compact structure,
easy installation, low running costs, easy maintenance and is safe and
reliable.

The heat exchanger is made of die cast aluminium with
radiating fins around and at the rear end. The combustion tube is located
inside the heat exchanger, and the burner assembly is fixed on the front end
of the combustion tube. Fuel is fed to the burner assembly through the fuel
inlet pipe by the aid of the fuel pump. It is ignited by the glow pin, which also
serves as a flame sensor after ignition. The flame is supported in the burner
assembly and sealed in the combustion tube. All combustion gases exit the
heater through the exhaust port.
Combustion air is fed into the heater via the combustion air pipe and is
supported efficiently by the combustion air fan, located on the rear of the air
motor. Cool air enters the air inlet, is heated by the heat exchanger, and is
pushed out the air outlet by the fresh air fan of the air motor assembly.
