General Inverter VFD – 30 KW

Energy Saving:

Energy saving is mainly manifested in the application of fan and water pump. While the fan, or pump type load adopts frequency conversion speed regulation, power saving rate will be 20% ~ 60%, this is because the actual power consumption of fan, pump type load is basically proportional to the third square of speed. When the average flow required by users is small, fans and pumps will use frequency control to reduce their speed, so energy saving effect is very obvious. But the traditional fan and pump uses baffle and valve to adjust the flow, so the motor speed is basically unchanged as well as the power consumption. According to statistics, fan and pump type motor power consumption is of 31% of the country’s power consumption, industrial power consumption is of 50%. It is very important to use variable frequency speed-regulating device on this kind of load. At present, the successful application involves constant pressure water supply, all kinds of fans, central air conditioning and hydraulic pump frequency control.
