Energy Saving Fixed Speed Vs Variable Speed

Compressor Motor Size in kW 45 / 60 hp

Annual Running Hours 2000hrs

Price per kW in Pence £0.26

Total Compressor Power kW = 50

Estimated Unload Power kW = 15

Fixed Speed Compressor Annual Electricity Cost £16900.00 + vat

By Switching to Variable Speed Compressor an Estimated Energy saving of 36-43% can be Achieved

Total Energy saving £5759.00 - £6796.00 + vat

Energy Savings of 30% can typically be gained, but energy savings as high as 50% are not uncommon on an oversized screw air compressor.

A Variable Speed Drive (VSD) has the ability to vary the output speed of the compressor’s air end depending on the actual pressure in the system.

The net result of this means that when air demand is low, the speed of the compressor is reduced, but when the air demand is high the compressor runs at full speed.

One of the benefits of a Variable Speed screw compressor is that it stops the compressor ‘unloading’ when the air demand is low, unlike a fixed speed machine which will vent unused air to atmosphere when not required. Venting unused air to atmosphere is a particularly wasteful method of flow control when compared to a VSD screw compressor which backs off the speed when demand is low, therefore saving energy. On a constant torque application such as a screw compressor, power is proportional to speed.

For example, if the screw compressor is loaded but the air demand is low and running at 50% speed, the energy savings will be 50%.
