Warm air heat recovery
All KAESER rotary screw compressors are designed for attachment of ducting, which is installed on-site. Neighbouring rooms and warehouse space, for example, can be heated with the warmed cooling air. PTG plate heat exchanger
Rotary screw compressors from the SM series (from 5.5 kW) upwards can be equipped with PTG systems. Depending on the size of the compressor system, the PTG heat exchanger is either integrated within the unit or is installed externally. SWT fail-safe heat exchanger
Rotary screw compressors from the ASD series upwards can also be equipped with SWT fail-safe heat exchanger systems. The SWT heat exchangers are always installed externally from the rotary screw compressor.  Heat is not only needed in winter
It goes without saying that heating is necessary during the winter months but it is also required for significant periods at other times of the year, such as in spring and autumn. This means that heating energy is actually required for approximately 2000 hours per year.
