The DTP22 series is equipped with a turbo compressor at both ends of the shaft. Thanks to its optimised engineering, the cooling is also integrated into the turbo. As a result, no external cooling components are required and high efficiency is guaranteed. The shaft of the DTP series is also optimally balanced. The reliability of the foil bearings is guaranteed and makes costly and complicated technology, such as magnetic bearings, unnecessary. For a high flow rate with a low installed power value, a 150 kW module is included in the DTP22 series in addition to the 225 kW.
