SIGMA CONTROL for SX to HSD series compressors

With its versatile control, monitoring and communication abilities, the SIGMA CONTROL is the ideal choice for applications requiring sophisticated communication functionality.
It is therefore fitted as standard on all KAESER ASD to HSD series rotary screw compressors and is optionally available for SX, SM, SK and ASK series compressors.
