75kw 100hp Variable Speed Drive Air Compressor Variable Flow Control

75kw 100hp Variable Speed Driven VSD / VF Energy-Saving Double Screw Air Compressor

GoodSeaA air compressor VSD series(inverter driven compressor) and YC series(permanent magnetic variable frequency compressor) are new-conception energy-saving product. By varying the speed of the drive motor in accordance to the change of the air capacity required,it regulates the actual power accordingly and thus saves the energy effectively.By adopting the electronic inverter system and the technology of supplying the exact air capacity required and precise pressure controlling,VSD air compressor not only directly reduces energy consumption by 30% but also brings many other benefits,such as stabilizing the network pressure,eliminating the peak current on starting,etc. VSD compressor serves as the best choice for the modern industrial and mining enterprises to save energy.

1. Advantages

1) Stable Pressure
The variable speed air compressor adopts PID for precision speed adjustment. Changes in the air amount of the system will be automatically tracked. The compressor will supply air at a constant pressure, which is the preset desired pressure plus or minus 0.1bar, to reduce power consumption.

2) Variable Flow Control
Adopt inverter to drive the compressor can adjust the rotation speed of the motor in real time according to the actual air compression. In case of high air consumption, the pressure remains unchanged, but the speed compensates automatically to meet the supply needs. When the air consumption is low, pressure is maintained constant and speed is automatically reduced to supply compressed air which is just enough.

3) No Current Impact during Starting
The air compressor is started via invert. The maximum starting current is 1.2 times the rated current for power frequency start. Hence, our variable speed air compressor exerts little impact on the grid during starting. It enjoys reduced stress and consequently prolonged service life.

4) High Economical Efficiency
Throughout the operating life of the air compressor, energy costs account for most of all costs. However, by using VSD, energy consumption is reduced by 30%.Therefore, the energy cost saved by a variable speed air compressor for three years is roughly equivalent to purchase price of the unit.
