How an Eberspacher AIRTRONIC Air Heater Works

As soon as the heater receives its starting pulse, the following processes are triggered by the central control unit ¹⁾:

  • Automatic safety check.
  • The burner motor starts, the combustion space is pre-ventilated, the glow plug is warmed up, the metering pump conveys fuel.
  • The glow plug ignites the fuel-air mixture, the flame is formed.
  • The hot combustion gases flow through the heat exchanger.
  • The hot air fan draws in room air or fresh air.
  • The heat of the combustion gases is transferred by the heat exchanger to this hot air.
