From powerful to whisper-quiet – the new air heater

What makes the Air Top Pro 25 the perfect choice for camping vehicles, trucks, vans, buses, specialty vehicles, boats, construction, and agricultural machinery? It stands out with the widest heating output range in its class and a long service life.
Whether it is a chilly autumn morning or a freezing winter day, in boost mode the Air Top Pro 25 heats the interior in very short time and maintains the individually desired temperature consistently thanks to its stepless heating power control.
Newly designed components - such as the heat exchanger, burner, and blower module - ensure maximum energy efficiency while reducing power consumption and noise levels. In the lower heating output range the Air Top Pro 25 operates whisper-quiet. The air heater can be installed both inside the vehicle and externally on the chassis.

Available from mid-2026.
