Warm air units

Direct and decentralised

SchwankAir warm air units are directly-fired gas warm air units that have repeatedly proven themselves for industrial space heating applications over the course of a number of years, thanks to their efficient burner technology. These heating units are particularly used for large space heating in buildings with low ceilings, narrow spaces and in buildings with high requirements for ventilation.

If just the basic heating in a hall is the main priority, then warm air units with quiet axial fans are best suited. For air renewal, on the other hand, warm air heaters with radial fans and duct systems creating a uniform distribution are the best choice.

Schwank engineers design each system of heating units individually. This is done to provide the most efficient system in each environment. For instance, in complex halls with office facilities, several floors or separate hall sections, a combination of classical Schwank infrared systems and Schwank warm air units can be an excellent option.

Schwank will offer its customers an extensive on-site analysis of their premises and undertake a comparison of the eligible heating technologies. This enables us to create building studies and a comparison of operating and energy costs, illustrating the efficiency of different types of heating system appropriate for any given application.
