New Atlas Copco air controller aims for energy savings

20 Aug 12 Atlas Copco Compressors has launched a new central controller that can be connected to up to sixteen compressors.

The ES 16 is designed to provide compressed air users with one central point of control for an entire network. It retrieves and processes information coming from compressors, dryers and other measurement equipment. According to Atlas Copco, the result is a dependable and efficient network that helps to save, on average, 10% of energy use in a compressor room.

“Customers want to continuously reduce their production costs without jeopardizing the availability of compressed air,” said Oil-free Air division product marketing manager Tamas Bakos. “Moreover, environmental awareness calls upon industrial facilities to limit CO2 emissions by reducing their energy consumption.” He said that even the most efficient machines can perform much better with the management of Atlas Copco central controllers.

Compressors and dryers can be connected to the ES 16 controller by means of a widely used CAN network. The device stores all machine and sensor data for up to one week. This allows users to see graphs and trends for analysis. It can also be consulted through the internet.

With its optional control feature, the ES 16 controller regulates air net pressure by starting/stopping the different sizes of machines and selecting their optimal operating points. Furthermore, it helps to keep air net pressure at the lowest possible level in order to gain additional energy savings, said the company. For example: lowering air net pressure by 1 bar not only reduces energy consumption by 7% but also air leakages by 13%. Atlas Copco also calculates energy savings of 10% can be achieved on average for turbo compressors and compressors fitted with variable speed drives (VSD).

As an option the ES 16 also offers increased control of ancillaries in a compressor room like pumps, valves and vents.
