Rotary Screw Compressors are very cost-effective for handling high volumes of gas in field gathering, vapor recovery and other applications. The LG30XXX is suitable for applications to 600 BHP and discharge pressures up to 200 PSIG. The LGL30XXX is suitable for applications to 800 BHP and discharge pressures up to 150 PSIG.
Low maintenance and high reliability are inherent with rotary screws because they have few moving parts. There are no valves, rings or packing to wear out or cause loss of efficiency.
Smooth operation results from no unbalanced forces and no pressure pulsation. No foundation is required and there are no piping vibrations from pressure pulsation. Natural gas engine or electric motor drives are equally acceptable with LG30XXX and LGL30XXX rotary screws.
LeROI Rotary Screw Gas Compressors are available in 12 models covering a flow range of 20 to 15,000 MSCFD and horsepower from 10 to 800.
Single-Stage operation from 5 PSIG to 200 PSIG maximum is possible with the LG30XXX and 150 PSIG for the LGL30XXX Series oil-flooded compressors. Compressor packages are therefore simple, reliable and inexpensive.
The gas differential pressure provides oil circulation for proper lubrication at differential pressures over 60 PSI. Optional oil pumps are available for with less than 60 PSI differential pressure.
Adjustable Vi allows discharge porting to be selected in the field to match the internal compression to the application requirement for maximum compression efficiency. All iron or steel construction with no copper or copper alloys makes these compressors compatible with natural gas, sweet or sour.
