Description

The HR 40 is a condensing air heater with an axial fan. The unit has a capacity of 40 kW and an efficiency of approximately 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 options
The HR 40 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 almost any situation like showrooms, garages or cash-and-carry shops.
