Survey:
KW3.0 Air heater (hereinafter referred to as the heater) is independent to the original engine system, it makes use of 12V or 24V direct current to drive. There are two kinds of control mode of  the heater: Automatic control mode and Manual control mode. The heater adopts light diesel which corresponds to the environmental temperature as fuel, and it can be started and operated normally at the temperature of above -40℃. The inhaled fresh air is heated to hot air through heat exchanger by the energy which comes from fuel burning, then blown to where it is needed. This type of heater owns the advantage of compact structure, light weight, high thermal efficiency, economize on electricity and fuel, easy installation.

After the heater starts, the glow plug comes into operation, the magnetic pump begins to supply fuel, combustion-supporting fan inhales combustion-supporting air from outside of car. The fuel generates the heat by burning in combustion chamber, which is taken by aluminum heat exchanger. The inner air pushed by the heat exchange fan brings heat to where it is needed through the surface of heat exchanger. And the combustion emission is discharged through exhaust pipe.
