New central controller from Atlas Copco
Latest ES 16 control device helps deliver 10% energy savings in compressed-air networks
ATLAS Copco have launched their new ES 16 central controller which can be connected to a maximum of 16 compressors. The device offers a central point of control for an entire compressed-air network as it retrieves and processes information coming from the compressors, dryers and other measurement equipment.
The result is a dependable and efficient network that can help deliver, on average, a 10% energy saving, say Atlas Copco. Compressors and dryers can be connected to the ES 16 controller by means of a CAN network. The device stores all machine and sensor data for up to a week, which allows users to see graphs and trends for analysis on the ES user interface or, for a longer period, by consulting them via the Internet.
The ES 16 controller regulates net pressure by starting/stopping different sizes of machines and selecting their optimal operating points. Furthermore, it helps to keep net pressure at the lowest possible level in order to gain additional energy savings.
For example, lowering net pressure by 1 bar not only reduces energy consumption by 7%, but also reduces air leakages by 13%. Atlas Copco experts have calculated that 10% energy savings can be achieved for compressors with variable-speed drives and turbo compressors.
The ES 16 device provides additional possibilities to increase the control and visibility in the compressor room for other equipment such as pumps, valves and vents. By adding optional flow and dew point meters, users can be sure that compressed-air production continuously provides the required amount of quality air with high efficiency and reliability.
‘Customers want to reduce their production costs without jeopardizing the availability of compressed air, while environmental awareness calls upon industrial facilities to limit CO2 emissions by reducing their energy consumption,’ said Tamas Bakos, product marketing manager for Atlas Copco’s Oil-free Air division. ‘Even the most efficient machines can perform much better with the management of Atlas Copco central controllers.’
