ALUP offers a brilliantly engineered solution to save energy in your compressed air production: the frequency driven compressor. A frequency driven compressor has a different work pattern than a fixed speed compressor, as you can see in the illustrated example, with lower peaks and a smoother air profile. The reason that the curve looks different for a frequency driven compressor is that it adjusts itself to the air demand and produces precisely the amount needed at the moment. A pressure sensor in the frequency driven compressor reports the exact pressure to the controller which gives then a signal to the inverter about the air demand situation. The inverter adjusts the motor speed depending on the pressure settings.
A frequency driven compressor saves in average between 25-35% in electrical cost compared to your previous compressor installation.  The technology, offered to you by ALUP, is a real piggy bank both for the environment and for your energy bill.
