There are many areas for potential cost savings when it comes to compressed air production and this is especially true for compressed air system monitoring and control. Kaeser’s latest generation Sigma Air Manager (SAM) provides users with the transparency and performance required to tap into these savings.
The new Sigma Air Manager with its adaptive 3-D-Control masters 3 key elements: 1) pressure flexibility, 2) control losses and 3) switching losses.
An all-in-one master control system and web server, the SAM plays a key role in optimising the availability and energy efficiency of compressor and blower stations alike. The new SAM is now more effective than ever, thanks to its innovative adaptive 3-D-Control.
Efficiency in compressed air production depends on how well the components within the compressor or blower station work together. In essence, the main factors to consider are operational reliability, compressed air availability and energy efficiency.
This is where the Sigma Air Manager (SAM) makes a real difference. With a powerful industrial PC at its core, the SAM not only controls and monitors the system as a whole, but also 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 factors that affect energy-efficient compressor control within a compressed air station, namely:
- Switching losses associated with compressor start-up and shutdown.
- Additional energy consumption for pressure increases above the required pressure.
- Control losses resulting from idling and FC losses.
In order to ensure optimum performance, the SAM constantly analyses the relationship between these factors, calculates the best possible result and controls the compressors accordingly.
Anticipation, key to better service
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.
