Industrial Utility Efficiency
In the absence of the control system, the air compressors were loading and unloading according to pre-set pressure bands, which forced the system to operate at higher pressures and run inefficient combinations of compressors in order to effectively match air demand. When switched on, irrespective of air demand, the control system was able to control all compressors on a single, tight pressure band and efficiently match output with demand.
