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.

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. When the user needs less air delivery, Variable frequency inverter can reduce the capacity and reduce the power consumption at the same.
