Bus heating systems: Air Top Evo 3900/5500


Evolution with higher performance and variety. The high-performance Webasto air heaters of the Air Top Evo series are the first choice for economical heating of the vehicle´s interior.

They generate highest possible comfort through quiet, fast, and even heating operation. Additionally to the temperature pre-setting with the thermostat or the pre-setting clock 1531, the multi-comfort controlling unit MC offers a total of five application possibilities.

In this way, individual wishes under various environmental conditions can be fulfilled (for example, saving battery energy with often-repeated use, fast heating with low outside temperatures, or adjustment of optimal heating behavior with low air pressure in high altitudes).

Several heaters can be connected in order to achieve a higher heating performance of up to 22 kW, creating an Air Top Evo System.
