1. Although the initial investment cost of the vsd compressor is high, the increased investment is returned through energy saving. The greater the change in demand, the greater the potential savings.
2. The working pressure range of VSD compressor is much narrower than that of power frequency compressor. They operate at lower delivery pressures while still maintaining the minimum working pressure required by the air system. They also provide more stable discharge pressure for all compressed air applications throughout the facility.
3. The net pressure of the VSD compressor can be set lower than the no-load pressure of the power frequency compressor.
4. The VSD compressor can be started/stopped at full system pressure. No need to unload, save time and effort. There is also no idling time loss, and no emissions loss that occurs during normal operation.
