Integrated intelligence:

KAESER Compressor’s revolutionary modular concept takes compressor controllers to the next level and beyond. Welcome to the world of SIGMA CONTROL 2
One size fits all
The SIGMA CONTROL 2 features a highly flexible modular design, yet its standard construction means that this versatile control system can be matched to suit the needs of any rotary screw compressor or rotary blower from KAESER KOMPRESSOREN’s extensive range. Comprising a main control unit and separate input/output modules, this modular concept therefore enhances communication and maintenance-friendliness.
Integrated web server
The SIGMA CONTROL 2 is equipped with its own web server, making compressor status visualisation possible via Intranet / Internet. Operational data and maintenance and alarm messages can therefore be viewed, with password protection, from any PC running a standard Internet browser. This feature consequently simplifies operation and maintenance, for example.
Security with RFID
The SIGMA CONTROL 2 provides high level security with its integrated RFID (Radio Frequency Identifica - tion) functionality. Not only does this technology en - sure secure log-in for users and/or KAESER service engineers, but also safeguards the system against unauthorised changes or operation. Manufacturerprovided passwords are no longer required.
The intelligent way to save energy
With multiple compressor control modes, a timer and base-load sequencing function, compressor energy consumption is now lower than ever before. The precision electronic pressure sensor enables exact switching differential selection to meet requirement thereby ensuring further savings.
