• 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.

Advantages of Oil Injected Direct Driven Screw Compressor:

1. Coupling driving system
2. Highly competitive price
3. Economic running costs
4. ISO, GA, SGS certificates

 

Oil Injected Direct Driven Screw Compressor features:

 

1 Drives and electrics

The almost loss-free power transmission guarantees reliable, high-performance compressor operation. The regular maintenance requirement is reduced to lubrication of the motor. All the electronic components are brand products of leading
manufacturers. rives and electrics.

2 Air end block – reliable centrepiece – Design in Germany

The centrepiece of Direct-driven Screw compressor is the air end, which is constructed and manufactured with the most modern production methods in China. The optimal air end for your compressor can be used on a modulating basis. In frequency-controlled units, where the operating pressure changes, adjustments can also be made on the frequency controller to optimally adjust the speed of the compressor to the compressor performance.

3 Electric motor

Only electric motors from well-known manufacturers of protection class IP54/IP23 are used in our Direct-driven Screw compressor. As a standard, the drive motors are monitored both thermally (via the thermistor of the motor) as well as electronically(overload protection via the frequency inverter).

4 Oil separation system

LGCD Direct-driven Screw compressor up to 132 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.
