Our new CSD series rotary screw compressors with frequency converter now feature a synchronous reluctance motor from Siemens for even greater efficiency.
The synchronous reluctance motor from our co-operation partner, Siemens, fulfils the requirements of the IEC 61800-9-2 standard and achieves top classification with IES2.
Inconspicuous from the outside, the innovation lies inside the variable-speed rotary screw compressor, more precisely in the drive system. In close cooperation with Siemens, a brand new synchronous reluctance motor was developed and integrated into the system. This delivers significantly improved efficiency, especially in the partial load range.
The reluctance motor and frequency converter are perfectly matched with one another and form the high-efficiency drive system of the new generation of CSD series compressors. This new system combines only the very best of both synchronous and asynchronous motors: Precision controllability combined with durability and service friendliness.
With its fully integrated design, the frequency-controlled rotary screw compressor assures maximum energy efficiency, lowest energy costs and proven KAESER quality.
CSD series rotary screw compressors with synchronous reluctance motors are classed as IES2 category machines and therefore belong to the elite efficiency class as per the IEC 61800-9-2 energy efficiency standard.
With this screw compressor series, customers around the world can now enjoy the benefits of minimum energy consumption and lowest possible operating costs - same size, even better performance.
Due to perfect matching of the motor and frequency converter, you benefit from the following advantages:
