Technical limits and conditions

The roof air conditioner is intended for vehicles with roofs with a thickness of 25 mm – 60 mm. The roof top air conditioner will operate at ambient temperatures between -2 °C ... 52 °C. The roof air conditioner is designed to be installed within ± 10 ° of the horizontal plane.

Technical description

The roof air conditioner supplies the vehicle's interior with cool or warm air which is without dust and dirt and can be dehumidified.

The roof air conditioner can lower the temperature within the vehicle to a certain level that depends on the type of vehicle, the ambient temperature and the cooling capacity of the roof air conditioner. Below an outer temperature of 16 °C the roof air conditioner does not cool anymore.

The roof air conditioner is operated with the following operating elements:

• Control panel
• Remote control (only some models, see List of models on page 6)
