provides an energy efficient heating for most applications and working environments with high ceiling heights, (appr. 6-40m). Heat accumulation in floors, walls and other surfaces means that the air temperature can be lowered giving 25-50% energy savings and yet achieving the same warmth comfort. EnergoInfra Industry, with its high operating temperature, may also be used out-doors, i.e. loading bay etc. The heater is approved in splash-proof IP44 design for wet and dry areas and out-door installations
