High Hardness Central Air Compressor , Oilproof Industrial Air Compressor

China Shanghai Rotorcomp Screw Compressor Co., Ltd certification
China Shanghai Rotorcomp Screw Compressor Co., Ltd certification
today 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.

—— Mr.Kerry Robinson from Australia

We'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.

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


Permanent magnet synchronous drive straight association-like host advantages


1.high efficiency and energy saving 2.fast response speed

3.no bearing less motor shaft current


Frequency conversion control technology characteristics


With vector control technology is particularly prominent advantages 1. energy saving effect is remarkable

2.variable flow control, gas supply stability 3.Soft Start: Start no impact


Equipped with highly efficient permanent magnet motor (PM motor),compared with ordinary frequency modulation motor, energy-saving performance is more outstanding!


Especially when the motor speed is low, the permanent magnet motor can still keep high efficiency

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.
