Espar / Eberspacher Hight Altitude Kit

This kit is required for heaters used at 2000-3000 meters above sea level.

With this high altitude kit an operation of the heater in regions up from 1400 until 3000 or slightly more metres are possible. After starting the heater, the height sensor which is enclosed with the kit measures the atmospheric pressure and send it to the electronic control unit (ECU). The control unit adjusts then the frequency of the metering pump. Because of this the heating power in height operation will be reduced by approx. 9% per 1000 metres. In regions below to 1400 metres the heater works in normal operation with the full heating power. 

Can be used with Eberspacher / Espar heaters that are H-kit marked. If you have an older type AIRTRONIC heater without H-kit marking and you need to use the high altitude kit, you would need to replace the old electronic control unit (ECU) to a newere model. Contact us for more details.

Please note, no special "high altitude pump" is required when this kit is installed.
