Has small slope amperage increase compared to other starting methods, hence it will prolong the service life of motor, contactor and compressor.
Provides best energy performance for load range of 30%~100%,and reduces the cost of operation by up to 25%.
By maintaining the set pressure ± 0.1 bar, the VSD will save a good portion of electrical consumption.
By adding only one VSD unit to the other conventional air compressors, as an energy efficient network, the whole system will improve the operation efficiency greatly.
By controlling the motor rpm that meets your air demand with minimum energy cost is the best energy saving control. Energy accounts for roughly 85% of a compressor's lifecycle costs. The purchase price, maintenance, service and other costs add up to only a fraction of the total energy cost consumed by the compressor. The VSD compressor can offer steady pressure supply. It can reduce the starting amperage (soft start eliminate current surge) and maintain the high power factor during whole range of loading which means higher motor efficiency.
