Innovative drive – pure efficiency
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 the SFC 18-30 & SFC 45-110S series. This new system combines only the very best of both synchronous and asynchronous motors: Precision controls combined with durability and service friendliness.
The perfect unit
With its fully integrated design, the frequency-controlled rotary screw compressor assures maximum energy efficiency, lowest energy costs and proven KAESER quality.
SFC series rotary screw compressors with synchronous reluctance motors are classified as IES2 category machines and therefore belong to the elite efficiency class as per the DIN-EN 50598 energy efficiency standard.
Noticeably more power
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:
Lower operating costs
Highest classification as per IES2
Increased availability and service life
Precision controllability combined with exceptional durability
