Mr.Kerry Robinson from Australiatoday I ran the compressor and I am very happy with the workmanship and the quality , it is connected to a nitrogen generator that requires around 0.8 MPA feed air from the 30 kw compressor we are commissioning it I have found that it loads and unloads from 25.5 kw - 30 kw this will be a huge saving on power consumption. -
Pedro Antonio from USAWe've been used Shanghai Rotorcomp compressors over 18 sets from 10hp to 160HP installed with Oxygen generator since 2008. Most of compressors still in good working conditions without much maintenance.

Product Description
Wear Resistant VSD Screw Compressor With Unique Driving Guard System
New generation Silent VSD Screw Air Compressor, 35%-50% than traditional VSD compressor.
1.The energysaving operating mode: permanent magnet motor can still maintain a high efficiency motor at low speed to ensure that the gas consumption in small, obvious energy-saving advantages.
Frequency range from 15% -100% (common frequency from 35 to 100 percent), Compared with the fixed speed compressor, saving 22% -37%
Compared with ordinary inverter compressor, saving 5% -12%
Fluctuations in gas consumption system the greater the energy-saving effect is more obvious Average standard compressors used in China for energy savings of more than 34%
2. Energy savings (energy conversion) when unloading system
According stationary air compressor gas consumption fluctuations, there will be time to unload, then compressor idling but needs 45% of the electricity consumption, but with VSD series air control, there is no unloading, there is no waste. If the system compressor station a few more, more energy-efficient.
Advantages:
1. World-leading "Made in Germany" Rotorcomp screw air end
2,25-30% energy saving than normal VSD compressor
3. wider 15-60hz adjustable-speed drive system
4. Intelligent touchable PLC control system
5. Double higher efficient VSD energy-saving motors in IE3 CE&MEPS
6. Unique driving guard system
7. ISO, TUV, GA, CE,SGS certificates
Shanghai rotorcomp Variable speed drive Screw Air Compressor adapting the amount of free air delivered to compressed air demand is the most economical operating method where demand for compressed air fluctuates considerably or where the stored volume is very small or where operating below peak load.
