Twin Screw Direct Driven Rotary Screw Air 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.
