Reducing energy costs

Given that energy costs to operate a compressed air system can total upwards of 70% of overall costs, reductions in power consumption can have a significant impact on the bottom line. Studies estimate the energy-saving potential of many air systems at up to 30 percent. Today's comprehensive system controllers can achieve up to two thirds of this potential.

Kaeser's recently introduced Sigma Air Manager offers a distinct advantage. It can control up to 16 compressors by communicating via a data bus to coordinate their load/idle performance and optimize energy efficiency. Sigma Air Manager's demand-related pressure band control maintains the lowest possible system pressure to ± 2 psig. Avoiding overpressurization provides significant energy savings and helps reduce leakage losses.
