Product (Diesel Air Heater)

Survey

KW2.0 Air heater (hereinafter referred to as the heater) is independent of the original engine system, it makes use of 12V or 24V direct current to drive.

The heater has two kinds of control modes: Automatic control mode and Manual control mode.

The diesel air heater adopts light diesel and gasoline, which corresponds to the environmental temperature as fuel, and it can be started and operated normally at a temperature above -40℃.

The inhaled fresh air is heated to hot air through a heat exchanger by the energy that 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, and easy installation.

Diesel Air Heater Technical specifications

Structural Principle

After the heater starts, the glow plug comes into operation, the magnetic pump supplies fuel, and the combustion-supporting fan inhales combustion-supporting air from outside the car.

The fuel generates heat by burning in the combustion chamber, which the aluminum heat exchanger takes.

The inner air pushed by the heat exchange fan brings heat to where it is needed through the surface of the heat exchanger, and the combustion emission is discharged through the exhaust pipe.

The structure of the hood-shaped case:

Installation of Fuel Supply System

Fuel for the diesel air heater can be supplied from the vehicle’s fuel tank or an additional independent fuel tank. It is not allowed to install the fuel tank in the cab or passenger compartment or any region that is possibly to cause fire if an independent fuel tank is used.

The elevation difference between the air heater and fuel pump, and between the fuel pump and the fuel pump, produces pressure from fuel to the fuel pump. The inner diameter and length of the fuel tube is related to the resistance of the fuel route. Please consider such factors for installation.

Diesel Air Heater Fuel pump installation

The fuel pump should be installed in places that can avoid heat radiation from the vehicle parts emitting heat, and in areas with cool air. Its ambient temperature should not exceed 20 °C.

Directions for the installation of the fuel pump are shown in the following picture.

When installing the fuel pump, please use the fuel pump holder supplied with the heater to hold the pump tight. The pump is fixed with the shock-reducing tightening piece.

Fuel Filter installation

The fuel filter should be installed before the fuel inlet port. Please make sure that the fuel flow is followed correctly. Its position shall conform with the above picture.

Installation of Fuel Tube

Only the flexible nylon tube, good light-resistance and thermal stability, supplied with the heater can be used as the fuel tube. The inner diameter of the tube is 1’ 2mm.

The position of the fuel tube should be away from flying stones and from any heat-emitting parts of the vehicle. A protective device can be installed if necessary. The fuel tube from the fuel pump to the main heater should be in any direction other than downward.

The fuel tube shall be tied in a proper location to make it fixed. The distance between two ties shall be less than 50cm. The fuel tube fittings supplied with the heater should be used for connections between fuel tube and fuel pump, fuel tube and heater, fuel tube and sucking tube of fuel tank and fuel tube and the fuel pump, the fuel tube and the heater, the fuel tube and the sucking tube of the fuel tank, and the fuel tube and the reducing. The fuel tube should tie with fuel tube clamps. Bubbles should be eliminated from the connecting places.

Installation of Fuel Taking Device

The openings on the fuel tank (or tank cover)for installation should be appropriate in size, with a trimmed brim and good evenness around the opening.

Good sealing is necessary for the base of the fuel taking tube. The bottom end of the fuel taking tube should be 30mm-40mm from the bottom of the fuel tank to suck enough fuel, and at the same time to avoid sucking in impurities and sediment on the bottom of the fuel tank.

If fuel is taken from the fuel pipe to the engine, the fuel pipe from the fuel tank to the fuel filter should be disconnected and re-connected with the thicker pipes of the reducing T.And the thinner pipe of the reducing T should connect the fuel pump of the heater via fuel tube fitting and tube. The installation angle must conform to the following picture, or the normal work of the diesel air heater will be affected.

After installation, the vehicle engine shall be started and then turned off after one minuteô s work to eliminate air trapped in the fuel sucking pipe.

Installation of Electrical System

Installation of Combustion Supporting Air Sucking Tube and Exhaust Discharge Tube

The combustion-supporting air must be sucked in from external fresh air outside the vehicle. The exhaust from combustion must be discharged into the air through an exhaust tube. Measures must be taken to prevent exhaust from re-entering the vehicle.

The tubes go through the outer wall or holes on the bottom of the vehicle. Measures must be taken to prevent the entry of splashwater. The tubes must be protected and can resist shock permanently.

Only the air inlet and exhaust tubes provided with the heater can be used. The air inlet tube is a corrugateþipe made of an aluminum tube whose it’s surface is covered by plastic and paper. The exhaust tube is a corrugated stainless steel tube. Please identify them and do not make mistakes during installation. To connect them with the heater, please use the supplied clamps to fix them tightly on the combustion supporting air inlet and exhaust tube vent, respectively.

The protective hood on the air inlet tube and exhaust tube vents must be kept in good condition. Do not damage them or remove them.

The air inlet tube and the exhaust tube should come outwards and downwards from the heater; a 4mm hole shall be prepared at the bottom of the tube to discharge condensation water. If the tube needs to be curved, the radius cannot be smaller than 50mm. Also, each tube’s sum of all curve angles shall not exceed 270N.

The opening of the tubes should not be opposite to the direction of the running vehicle.

The tube openings should not be blocked by slurry, rain, snow, or other dirt.

The exhaust tube should be installed far from the plastic parts or other objects with poor thermal resistance of the vehicle body.The exhaust tube should be fixed appropriately. The exhaust vent should be downwards, perpendicular to the road surface with an angle of 90£ 10£ . To ensure such an angle, the fixing clip for the exhaust tube should be 150mm from the tube end.

Warning: Violation of the above requirements may cause fire.
