Dantherm FH 20-40 – tent heaters
The heaters are based on the indirect fired (clean air) principle to avoid introducing combustion or fumes into occupied spaces. With their industry-leading warm-up capabilities, the forced air system heaters are essentially self-contained and require no more than an external source electric power and some fuel in the built-in tank. They run on almost all diesel fuels.
Specifically developed to provide heating in tents or other temporary and transportable buildings, FH Warm Air Heaters are suitable for outside installation with supply and return air ducted to the tent or temporary building.
