New: “Sigma Air Manager” with adaptive 3-D-Control
The key to enhanced compressed air efficiency
There are many areas for potential cost savings when it comes to compressed air production. This is especially true for monitoring and controlling both of compressor and blower stations. As an advanced compressed air management system for up to four, eight or sixteen machines, Kaeser's latest generation Sigma Air Manager (SAM) provides users with the transparency and performance required to tap into these savings. With its all-in-one master control system and web server, the SAM plays a key role in optimising compressed air availability and energy efficiency. The new SAM is now more effective than ever, thanks to its innovative adaptive 3-D-Control.
The efficiency of a compressed air system not only depends on operational reliability, availability and energy efficiency, but also on how well the components within the compressor or blower station work together. This is where the Sigma Air Manager (SAM) makes a real difference. With a powerful industrial PC at its core, the SAM monitors the system as a whole and provides the user with exceptional transparency of operations processes, energy consumption and costs. The latest version uses Kaeser’s innovative and adaptive 3-D-Control (patent-pending) which considers the three crucial "dimensions" that affect energy-efficient compressor control within a compressed air station:
1. Switching losses associated with compressor start-up and shutdown.
2. Additional energy consumption for pressure increases above the required pressure.
3. Control losses resulting from idling and FC losses.
In order to ensure optimum performance, the SAM constantly calculates the best possible result and controls the compressors accordingly. This strategy therefore achieves impressive energy efficiency even with widely fluctuating compressed air demand. An added advantage is that the number of switching operations – i.e. the number of start-ups, load/idling switching sequences, and shutdowns – is also considerably reduced.
With Kaeser’s adaptive 3-D-Control technology, the SAM also strives to deliver best possible pressure performance values. The decisive factor of course is that the system pressure, in so far as possible, should not fall below the prescribed pressure required by the application. One of the main problems in maintaining the necessary pressure using control processes up until now stems from the system-inherent lag in the reaction of compressors and blowers – this is particularly evident in regard to the dead time between a start signal and the commencement of air delivery. Adaptive 3-D-Control however makes allowances for this delay through anticipatory switching operations and it is this adaptive optimisation which enables the required pressure to be maintained better than ever before. Sudden, large increases above required pressure therefore no longer occur, as these are seen as inefficient within the context of these dimensions. Moderate increases above required pressure aren’t a cause for concern in most applications. The 3-D-Control optimises the compressed air station’s performance within this "pressure tolerance" range, taking into account the “three dimensions” of energy efficiency mentioned above.
The Sigma Air Control Basic visualisation tool is also included as standard. Information provided includes machine status, current SAM control panel status, and a network pressure log for the previous operating phase, as well as maintenance and alarm messages. Furthermore, password-protected data stored in the SAM’s long-term memory can be displayed in graphical format for periods going back as far as a year using the optionally available Sigma Air Control Plus version of Kaeser’s advanced visualisation software. This capability provides the basis for detailed compressed air audits and allows the user to keep a constant eye on compressed air costs and system performance. In addition, the specific power of all connected compressors or blowers within the system can be displayed in comparison to a reference value. This allows the user to determine at a glance if the compressor system is performing as efficiently as it should be.
Allowing connectivity to Kaeser's Teleservice facility, the SAM is also able to control, analyse and monitor performance of older Kaeser or even third party compressors and components within the compressed air station to ensure optimum performance at all times.

Its adaptive 3-D-Control also takes compressor switching losses into account, thereby enhancing energy efficiency even further.
