Wanger mobile electric heaters is a combination of a joint unit fan motor and radiator made of. Applies to all types of air recirculation allows workshop, when the air when free of dust, flammable gas, can be used as circulating air heating purposes. Mainly by the air heater and fans, air heaters cooling, then the fan sent, so that the indoor air temperature is adjusted. Air heater by heating tubes. Oil heater from the combustion chamber and burner head, fan, motor, pump, tank components. Motor starts to drive the air compression pump, and ejected from the nozzle, and because of the Venturi effect (this effect is in the vicinity of high fluid flow will produce a low pressure, resulting in adsorption), the fuel tank at the filler aspirated the atomization. At the same time the ignition is started, the atomization of fuel nozzle out of ignition, combustion in the combustion chamber. Motor-driven fan through the combustion chamber and mixed with the combustion gases through the ambient air within the hot air blowing out of the front of the outlet. There is a link on photoelectric sensors inside the machine control circuit, keep monitoring the operation of fan heaters and cut off the circuit in exceptional circumstances.
