Kaeser Compressors releases new rotary screw compressors

The CSD/CSDX range of rotary screw compressors from Kaeser Compressors are more efficient than ever before

Rotary screw compressors are the dependable backbone of any industrial compressed air supply. With a multitude of features, the new CSD/CSDX range from Kaeser Compressors fulfils this role more efficiently, dependably and economically than ever before, whilst at the same time reducing its carbon footprint.

The most important feature of these new compressors is their low energy consumption, which has been achieved via a number of innovative measures.

This ‘.6’ iteration of the CSD/CSDX series uses highly efficient speed-controlled (IE5) or fixed-speed (IE4) drives. The centrepiece of all compressors in this series is the rotary screw airend with flow-optimised Sigma Profile rotors, specially developed for this performance range.

These and other improvements, such as speed-controlled fan motors, have enabled the energy efficiency of the compressor system to be enhanced, which has significantly reduced energy consumption. The new design has also led to improved accessibility to components for ease of maintenance.

Featuring motors with power from 45 to 90kW, models from this series can cover delivery volumes from 8.4 to 19.4 cubic metres/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, whilst the required refrigerant charge is also around 25 per cent 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. As with the standard systems, these versions are designed for optimised cost-efficiency, operational reliability and maintenance-friendliness.

Kaeser rotary screw compressors are produced in Germany to strict quality standards and requirements and a high level of durability means they can serve a company for many decades to come. Many of the components used are recyclable.
