Kaeser Sigma Air Manager 4.0

Kaeser Compressors has released the latest version of its Sigma Air Manager, its master control system for compressed air production and treatment components. SAM 4.0 optimises pressure values, automatically adjusts compressor system air delivery to accommodate fluctuating pressure demand and optimises system efficiency based on control losses, switching losses and pressure flexibility. Moreover, the end user can take advantage of services such as Sigma Smart Air for predictive maintenance. These features are designed to not only boost efficiency, but also reduce energy costs.

SAM 4.0 takes advantage of Kaeser’s adaptive 3-D^advanced Control, which takes into account additional factors, aside from switching losses (start/stop), that affect compressed air system energy efficiency. These include control and idling losses, frequency converter operation and pressure flexibility (average increase above required pressure). The optimisation method predictively calculates the optimum achievable configuration and adjusts the connected components accordingly, based on the specific pressure required by the user.

The product supports operation in 30 languages, while the easy-to-use 12″ colour touch screen shows at a glance whether the station is operating in the ‘green zone‘ from an energy management perspective. Operating status, pressure history, free air delivery and power consumption, as well as maintenance and any error messages, can be easily displayed and analysed — both in real time and retroactively. Using a PC and network connection, this data can be accessed conveniently from anywhere, not just at the machine itself.
