• Mr.Kerry Robinson from Australia
    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.

    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.

Description:


Fully seal & double screw,dual shockproof,smooth operation,can be installed anywhere.
With a exquistie shape and compact structure and cover a small area.
Large displacement,stable pressure and high efficiency.
Low exhause temperature (only 7 °C~10°C higher than the ambient temperature)
Safe,liable,smooth operation,little noise and long maintenance cycle and using life.
The intelligent control system completely satisfy the continuous cooperation without man work.
Many screw air compressors operate together and start or shut down automatically
according to the air amount,and no man-work is needed.
It is more energy saving for a single compressor can adjust air demand automatically according to the users' air amount(frequency conversion type).
The degree of tightness of the belt can be auto-matched with the flexible belt. Through adjusting the tensility, the loss of the pressure and efficiency can be reduced to the lowest point and increase the efficiency.
