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.

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.
The benefits of rotorcomp VSD air screw compressor
>Smooth starts and stops within seconds
>Continuous volume flow regulation from 25-100%
>Adjustable-speed drive from 15-60hz
>minimization of wear and maintenance costs
>No power-peaks during start-up
> nearly no idling
Reduce Energy Consumption
The costs of power consumption account for 70% or more of all costs during the operation. The electric charges of running air compressor account for more than 40% of all the electric charges in the factory.
The requirement of compressed air fluctuates violently in different time every day, different weeks, or different months every year. The range of fluctuation is 40% to 80%, Rotorcomp adjustable-speed drive screw compressor can meet the user’s requirement exactly. With frequency conversion soft start reduce in-rush starting current, reduce wear on electrical switch gears and motor windings.
Also maintain less power during starting and stopping of motors and increase protection to motors. Also reduce peak demand and improve power factor.
