Variable Velocity Compressors

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

By far the most widespread kind applied in the air compressor business makes use of a variable-frequency drive, and this is used to convert the AC input energy to DC after which back to a quasi-sinusoidal AC energy, with the use of an inverter switching circuit.

The key positive aspects are, reduced energy price, reduced power surges, and the delivery of extra continuous pressure. The downside may be the heavy expense in the 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 power efficiency of these compressors final results in worthwhile savings on energy costs for users with fluctuating compressed air specifications. 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's going to be switching on and off and most likely operating inefficiently.

As energy charges have improved it has become a lot more price efficient to use these compressors. These kinds of compressors will only produce the volume of compressed air expected and can be an incredibly efficient way of saving energy. If greater than a single fixed compressor is utilized, it may be a lot more price effective to possess only one compressor to deal with the variable part of the air demand. Research have proven that greater control, housekeeping and upkeep could save operators as much as a single third of the energy applied across their compressed air systems.

You will discover other forms of air compressors and these can include:

o Rotary screw compressors

o Variable speed compressors

o Vane compressors

o Reciprocating compressors
