Air heaters Application concept
Air heaters Advantages
The advantages of Webasto air heaters Optimum heat output at high altitudes thanks to altitude sensor (Evo range) and altitude mode integrated in MultiControl Heating power from 0.9 kW to 5.5 kW Very compact heater for easier and faster installation Smooth blower and burner operation for low noise and fuel consumption Hot air is channeled and distributed through the motor home, ensuring a constant temperature Precise and stepless cabin temperature control Very fast heat-up phase Low noise operation Diesel-fueled, directly fed from the tank More space inside due to the possibility of outside installation Heating while driving allowed in all countries
How Webasto air heaters work When the unit is switched on, the fuel pump feeds fuel from the vehicle fuel tank to the heater. Here the fuel is automatically ignited by means of a glow plug. In the combustion chamber, a flame is lit which heats up the heat exchanger. The unit takes air in from the outside for combustion purposes and the combusted exhaust air is discharged to the outside. During heating, the integrated fan takes in the air to be heated through the inlet and feeds it through the unit. As the air flows through the heat exchanger, it heats up and is then distributed through the outlet. The connected hot air pipes now spread the air evenly throughout the vehicle interior. Due to the unit’s own separation of the combustion circuit from the heating circuit, there is no impairment of the quality of the hot air. A temperature sensor constantly measures the interior temperature and automatically adapts the heating power output by adjusting the amount of air passing through the unit. In this way, the temperature selected by the user is rapidly reached and maintained at a constant level. After the unit has been switched off, the combustion process is terminated in a controlled manner. For this purpose, the unit briefly goes into re-run mode to cool itself down. It is then immediately ready for restarting.
Air heater can be installed inside or underneath the vehicle
