Energy consumption made visible
Hemmerich and his team took the decisive step towards lowering compressed air consumption with the introduction of the energy efficiency module MSE6-E2M from Festo. “The energy efficiency module gave us the opportunity to see the amount of compressed air we were using during operation of a line,” explained Hemmerich. “In addition, we were able to determine how the compressed air requirement changed when we switched off individual consumers. We were thus able to locate leaks and eliminate unnecessary consumption.”Automatic shutoff of the compressed air in the standby mode of the MSE6-E2M made it possible to establish how quickly the system empties. The energy efficiency module MSE6-E2M immediately reports any unusually quick pressure drop to the system controller.
At the same time, the automatic pressure shutoff function prevents further compressed air consumption while the system is not in operation. Thanks to its onboard intelligence and the specific model for operating the compressed air systems, the MSE6-E2M independently identifies when a system is in production and when it is at standstill. At Unilever, however, they decided to use the alternative option of operating the MSE6-E2M via the system controller so that all information was merged centrally.
Significantly reduced energy consumption
Thanks to the new condition monitoring for the pneumatic components of his Magnum machine, Alexander Hemmerich now has continuous process-relevant data. The MSE6-E2M regularly exchanges important measurement parameters, such as flow, pressure, and consumption, with the machine controller via Profibus. It is easy to operate via the control panel. “The Festo energy efficiency module has enabled us to reduce our air consumption on the Magnum production line step by step. And the Profibus connection has the advantage that we don't have to add any more cables when converting our existing systems.”On the Magnum line, the costs for compressed air consumption were reduced by more than 500 euros per year.
