Kaeser Compressors CSD/CSDX rotary screw compressors

The CSD/CSDX range of rotary screw compressors from Kaeser Compressors are designed to perform with low energy consumption. The ‘.6’ iteration of the CSD/CSDX series includes drives with the best possible efficiency class, whether speed-controlled (IE5) or fixed-speed (IE4). The centrepiece of all compressors in the series is the rotary screw airend with flow-optimised Sigma Profile rotors, specially developed for this performance range.

Other improvements, such as speed-controlled fan motors, have enabled the energy efficiency of the compressor system to be enhanced. The new design has also led to improved accessibility to all relevant components and therefore increased maintenance-friendliness.

Featuring motors with power from 45 to 90 kW, models from this series can cover delivery volumes from 8.4 to 19.4 m³/min and are designed for pressures up to 15 bar. Particularly at low pressures, even higher delivery volumes can be achieved.

The environmentally friendly system design even extends to the fluid filter elements: they are metal-free and after use can simply be thermally disposed of without need of further treatment.

In addition to the standard versions, versions with an add-on refrigeration dryer module are available, which permit both compressed air generation and drying in a comparatively small space. The refrigeration dryer is dimensioned for high ambient temperatures and operates with very little pressure loss. In comparison to the previous version, energy consumption has been reduced significantly, while the required refrigerant charge is also around 25% lower. The dryer is accommodated in a separate housing and is therefore not negatively influenced thermally by the exhaust air from the compressor.

The CSD.6 and CSDX.6 are both available with variable speed control.
