Low Life Cycle Costs

Our comprehensive approach to life cycle cost management: Superior efficiency, easy operation, service-friendliness, and a global service and consulting network with fast response times.

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.
