Under full load condition, permanent magnet compressors can supply the maximum air output under the minimum energy consumption, and when the load rate is lower by 20%, can still guarantee the efficiency. permanent magnet compressors always stays as much as 95% of running efficiency within the scope of the whole gas regulating speed. Save bandwidth control pressure waste of electricity (Variablefrequency energy saving): In order to avoid the frequent starts that result in the cause to the unit, the impact on the grid,stationery compressor must set up a minimum of 1bar pressure range (The minimum and maximum pressure of the air compressor), the control of machine needsto have a pressure gradient when some units are used together, the pressure of the system will be wider VENUS series are of variable frequency control, can start and stop with unlimited times, so no need to set the pressure range, it only needs to set a pressure point, every saving of 0.14 bar pressure range, it will save the energy consumption by 5-7% for the whole system. VENUS series double screw host with its continuous optimization of rotor type line and internal structure, provides industry leading level specific power. The host energy efficiency is above the first level of energy efficiency of the national standard
