Controller for Compressed-Air Network

May 28, 2012
Energy savings by collecting data, optimizing performance for compressors, dryers, etc.

ATLAS COPCO launched the ES 16 central controller that connects with up to 16 compressors to create a single, centralized point of control for an entire compressed-air network, retrieving and processing information coming from the compressors, dryers and other measurement equipment. The result is a dependable and efficient network and thus helps to save on average 10 % energy.

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 up to one week. This allows users to see graphs and trends for analysis on the ES user interface or for longer period, they can optionally consult them through the Internet.

The ES 16 functions as the central point for a network of up to 16 air compressors, dryers, or other measuring devices, to collect and managed data and save on average 10% of energy consumed.

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

The ES 16 controller provides additional possibilities to increase the control and visibility in the compressor room for other equipment like pumps, valves, and vents. Optionally adding flow meter and dew point meter, users can be sure that the compressed air production continuously provides the required amount of quality air with high efficiency and reliability.

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

Atlas Copco offers other central controllers, from the ES 4 that connects four compressors, up to the ES 360, which can connect 30 compressors and 30 dryers.
