Sigma Air Manager

Integrated performance for maximum energy savings

An orchestra is far more than simply a collection of musicians. It is the conductor who brings together the individual players to create a single powerful and distinctive sound. The Sigma Air Manager (SAM) from Kaeser plays a very similar role within a compressed air supply system: Utilising the latest master control and web server technology, the SAM is an invaluable tool for ensuring optimised air system availability and energy efficiency.

Three dimensional control for perfect balance and efficiency

	Adaptive 3-D-Control: The key to enhanced efficiency The adaptive 3-D-Control detects the three dimensions of control losses (idling and FC losses), switching losses (starts/stops) and pressure flexibility (average increase above demand pressure), as well as their associated energy expenditure. In addition to optimisation of compressed air station energy consumption, the Sigma Air Manager is able to achieve best possible pressure performance. Needless to say the required pressure for the application is a key determining factor. When operating compressors with conventional control systems there is a certain inherent lag in system response, but the adaptive 3-D-Control takes care of this with intelligent predictive switching. As is usual for any optimisation calculations, the Sigma Air Manager also requires some room for manoeuvre – in this case the so called “pressure range”. Even with varying compressed air consumption the Sigma Air Manager automatically matches the compressor delivery rate to match actual requirement and thereby ensures minimal energy consumption at all times. Kaeser’s Sigma Air Control Plus visualisation software also provides detailed information regarding compressed air system energy consumption, as well as many other aspects, so the operator can instantly tell whether the system is operating within the desired parameters.
Sigma Air Control Plus: Display of system pressure Network pressure over a specific time period is also shown together with pressure performance (in %). The less often the pressure deviates from the required pressure, the higher the pressure performance.
Sigma Air Control Plus: Graphical display of specific power The graph shows the specific power of the compressors within the compressed air station compared to the so-called reference value – this value is the specific power of all connected compressors at maximum working pressure.
