Compressor controls: SIGMA CONTROL 2


Integrated intelligence

SIGMA CONTROL 2 coordinates compressed air generation and consumption. With its intelligent control, this advanced controller prevents inefficient energy usage, especially in part load operation. SIGMA CONTROL 2 is based on advanced industrial computing technology to protect the unit as well as allow networking and remote monitoring of system status and operations. Interchangeable input and output modules enable flexibility for working with to external communications systems. SC2 is available on all Kaeser screw compressors as well as integrated blowers and DNC booster packages.         


SIGMA CONTROL 2: for all rotary screw compressors, rotary screw blowers, reciprocating compressors, boosters, and rotary lobe blowers

SIGMA CONTROL 2 is based on advanced industrial computing technology. Interchangeable input and output modules enable flexibility for working with Kaeser rotary screw compressors, rotary screw blowers, reciprocating compressors, boosters, and rotary lobe blowers, as well as to external communications systems.

The benefits of SIGMA CONTROL 2

  • Troubleshooting support:
    The industrial PC saves the last 200 operational events, helping you and Kaeser Support quickly find and reproduce faults. Furthermore, the built-in web server enables you to display operational data, maintenance and fault messages on any PC.
  • Easy operation:
    Intuitive menu navigation and 30 available languages simplifies controller operation
  • Quick software updates:
    Software updates and operating parameters can be quickly uploaded and transferred via the SD card slot. This minimizes service costs and allows the SD card to be used for (long-term) storage of key operational data.
