Sigma Control Mobil™
Advanced compressor controller technology
  • By accessing electronic motor management, the Sigma Control Mobil™ system optimizes compressed air availability and fuel efficiency. The system is shock and vibration proof per IP 65 electrical protection.
  • Its functions include operational monitoring as well as precise system diagnostics.
Timesaving user-friendly operation
  • The highly intuitive interface only needs three buttons to operate the entire system.
  • In addition, the automatic monitoring feature can shut the compressor down as required.
Precise pressure settings save fuel
  • Using the arrow keys, system pressure can be precisely adjusted in 1.5 psig increments on the Sigma Control Mobil™'s display.
  • This not only enhances flexibility but, in combination with the electronic inlet valve control, enables significant energy savings-especially for part load operation.
