Variable Speed Compressors are also know as variable speed drive compressors, and are air compressors that reap the benefits of variable speed drive technology. They employ a special drive which controls the RPM (Revolutions Per Minute) speed of the compressor, and this in turn saves energy when in comparison to its fixed speed equivalent.

The most common kind utilised in the air compressor sector makes use of a variable-frequency drive, and this really is employed to convert the AC input energy to DC and then back to a quasi-sinusoidal AC power, with all the use of an inverter switching circuit.
The primary rewards are, reduced energy price, lowered energy surges, and also the delivery of more continual stress. The downside will be the heavy expense of your drive and their sensitivity to heat and moisture.
They combine a speed inverter, which converts the AC signal to DC and speeds up or slows down the motor, having a pressure transducer to precisely match the compressed air output to demand. The energy efficiency of these compressors outcomes in worthwhile savings on energy expenses for users with fluctuating compressed air requirements. The demands for air in almost every single compressed air technique fluctuate to some extent. If a compressor has a fixed speed, then it implies that it is going to be switching on and off and likely running inefficiently.
As energy costs have increased it has come to be a lot more cost powerful to utilize these compressors. These types of compressors will only generate the volume of compressed air required and can be a really effective way of saving energy. If more than one fixed compressor is utilized, it might be a lot more price powerful to possess only one compressor to manage the variable part of the air demand. Research have established that superior handle, housekeeping and maintenance could save operators as much as one third on the power used across their compressed air systems.
You will discover other sorts of air compressors and these can consist of:
o Rotary screw compressors
o Variable speed compressors
o Vane compressors
o Reciprocating compressors
