The gas warm air heaters are instantly ready for use, without long lead time.

All units have a high degree of efficiency of 92 % and more. The heat is available immediately after starting the heater. No lead time as supposed to a wet heating system. In large rooms, you can also just heat single areas.

The core of the units is the patented stainless steel heat exchanger for a high air flow. The atmospheric high-performance burner is equipped with newly developed burner lances, electric ignition and ionization control. There are no weld seams close to the high-performance burner for high durability, so only little maintenance is required.

The hot air is emitted by powerful, yet silent axial fans. Optimized air outlet lamellas ensure a perfect air distribution. The fans permit the heat exchanger to transfer the heat optimally, the combustion chamber cannot overheat. The number of fans is adapted to the units’ power.

Mounting the units is very simple, they are designed for wall-mounting or to be suspended from the ceiling. They can be installed with connection to a fix chimney or with a flue gas pipe system through the roof or the wall.
