New controls can reduce compressed air costs by 30%

Published:  17 June, 2009

Atlas Copco has launched the fifth generation Elektronikon graphical display controller (installed as standard on the GA+/GA VSD) while expanding the Energy Saving (ES) System to control, with the ES6i, up to six variable speed drive or fixed speed compressors simultaneously.

The Elektronikon graphical display controller is a colour display, housed on the compressor, that shows several compressor and dryer parameters while built-in algorithms automatically implement energy saving cycles for both fan and dryer. Additional features such as dual pressure band and timer-based controls enable Atlas Copco to maximize energy savings by matching the operating pressure to air demand.

The optionally integrated Energy Saving Control System, ES6i, is capable of regulating and sequencing up to six variable or fixed speed compressors; while optimizing the customer's installation by reducing the overall working pressure band of each compressor to meet the varying air demand.  The possibility to manage up to six variable speed compressors with one integrated controller (up to four compressors with the ES4i) reduces installation costs while minimizing energy and maintenance costs through reduced pressure band. Depending on the compressor configuration and air demand, the improved ES control system can reduce yearly running costs up to 30%.

Developing the fifth generation Elektronikon Graphical display controller, Atlas Copco"s engineers focused on the importance of a user friendly interface.  Clear and easy communication keeps the user informed about the operating condition of the unit therefore reducing operation and maintenance cost.

The hardware includes a new human machine interface with durable keyboard and a user-friendly navigation system.  The Elektronikon graphical display controller has a high quality 3,5 colour display.  The built-in web-server technology is a standard feature with no additional cost providing, through Ethernet communication, instant online compressor status visualization.  The graphic visualization provides service intervals in real time and displays a graphical service plan assisting in preventive maintenance.  Customers can select one of 32 languages while all registered data is stored for later use.  The optional AIRConnect allows for remote or local monitoring (through the phone or wireless internet connection) for additional on- or offline readings.
