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.

22KW 35-50% Energy-saving variable speed screw Compressor in TUV certificates 5 years warranty
New generation VSD Screw Air Compressor, 35%-50% than traditional VSD compressor.
Control Panel: Intelligent microcomputer-based control technology can monitor and control in all aspects the complete machine following your instructions.Remote control realizes unattended operation.
Oil filter: Rotary filters are applied to completely remove the impurities in the lubricating oil,easy to replace and free of oil impregnate.
Cooler: It is designed for low temperature difference to increase heat exchang area,and ideal to be applied to high-temperature and high-humidity operating environment.
Motor: First-class motors are adopted,with the level of protection being lp55 and insulation level being F.
Acoustic enclosure: It is designed into fully-closed mute box,in which soundabsorbing sponge are attached for effective absorption of noise,thereby making the noise 3-5dB(A)lower than that made by the compressors of the same kind. It is reasonably structured overall and very easy to maintain and repair.
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. When the user needs less air delivery, Variable frequency inverter can reduce the capacity and reduce the power consumption at the same.
