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. They are particularly used for large space heating in buildings with low ceilings, narrow spaces and in buildings with high requirements for ventilation. If the basic heating of spaces is paramount, recirculation units with quiet axial fans would be the logical choice. In case of air exchange, warm air units with radial fans and duct systems are used for uniform distribution.

If heating in a hall is a 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 for uniform distribution are the best choice. Schwank engineers design each system individually. Especially in complex halls with office facilities, several floors or separate hall sections, the combination of classical Schwank infrared systems and Schwank warm air units can be advantageous.
