• 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.

Product Description

Cheaper Direct Driven Industrial Air Screw Compressor 315Kw 420Hp in TUV,CE,ISO certificates!

Cheaper Direct Driven Industrial Air Screw Compressor features:

1,Economic running costs
2,Good environmental adaptability
3,Extraordinary cooling system design
4,screw air end design by R&D center in German

5,GA,GC,ISO,ASME certificates

 

 

First, the curved face of the rotors engaged fully, thus contributing to the formation of a hydrodynamic lubrication film, reducing the contact zone of the lateral leakage, improve compressor efficiency; as well as to improve the processing, test performance of the rotor.

 

Second, using the design ideas of bigger rotor, bigger bearing, low-speed ", speed lower than other brands up to 30 ~ 50%, this could reduce noise and vibration, reducing the compressed air temperature and improve the rigidity of rotor and prolong its life, reduce sensitivity to the impurity and the oil carbide.

 

Third, fully meet or exceed the national standard ISO19153-2003 "air compressors energy efficiency limit !

Fourth, Oil separation system

LGCD Direct-driven Screw compressor up to 760 kW are equipped with external separators that can be changed in a simple spin-off/spin-on process. Larger units have an internal separator cartridge. Due to the excellent separation efficiency of the system as a whole, the compressors can be used in the pressure range of 5.0 to 15.0 bar. Special pressures on request.

 

 

Frequency inverters (optional)

The frequency converter minimises idle times and optimises supply with fluctuating compressed air requirements. Start-up peaks are avoided and the compressor’s delivery rate is controlled continuously – that saves electricity costs! The total costs for your compressed air supply are significantly reduced and investment costs are amortised in the shortest possible time.
