Products introductions &advantages for 7.5-630kw oil injected PM VSD ( permanent maget variable speed driven) Rotary Screw Air Compressor:
Motor:
1) .Oil cooling high efficiency permanent magnet motor
2). Insulation grade F, protection grade IP54,adapt to the high dusty environment. IE4 Efficiency motor efficiency.
3).Max.RPM 1500,low noise, high efficiency, better life-span.
4).Split design, easy maintenance. Easy for installation and service.
5).Without gearbox design, motor is connected directly with rotor through the coupling, high transmission efficiency.
6).Low temperature rise, independent cooling fan design, so that the motor cooling is not affected by the speed regulation.
7).With PT100 temperature protection switch to avoid high temperature degaussing.
8).Large speed range, high precision and large adjustment range.
9).Premium Magnetic material resist more than 180ºC temp
10).Fantastic Energy Saving, save up to more than 30-40%
Inverter :
1). dual variable frequency inverter
2).Dual variable frequency system: permanent magnet motor variable frequency + cooling fan motor variable frequency , one-piece integrated structure, extreme energy saving.
3).Constant pressure air supply: the supply pressure is precisely controlled under 0.01 MPa.
3).Constant temperature air supply: constant temperature set at 85 ºC, with the best lubrication
4).Eliminates empty load, reduces the empty load energy consumption by 45%.
Eliminate overpressure
5).Large Frequency range 30%~ 100%
6).Vector air supply, accurate calculation, ensure that the air flow of Compressor is consistent with the demand of the user system.
