Description

The HR 50 is a condensing air heater with an axial fan. The unit has a capacity of 50 kW and an efficiency of approxiamately 106%. The pre-mix burner and the system fan modulate both independently and stepless back to 30%. These both features ensure a constant and even temperature in the building. 

More possibilties

The HR 50 is suitable for natural gas or propane gas.
It is also possible to mount the unit up to an angle of 45 degrees. Together with the louvres, it is then possible to blow warm air vertically. The compact and attractive design of the heater makes it possible to install it in various commercial buildings.
