LeROI provides rotary screw compressors for gas to the oil and natural gas, and industrial and process industries. Rotary screw gas compressors are very cost-effective for handling high volumes of gas in field gathering, vapor recovery, and a wide range of other applications.
The HG20 Series natural gas compressor is suitable for applications to 300 BHP (223.8 KW) and 350 PSIG (24.1 BARG) discharge pressure.
Low maintenance and high reliability are inherent with rotary screws when compressing natural gas 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. There are no piping vibrations from pressure pulsation.
Direct coupled natural gas engine or electric motor drives are equally acceptable with the HG20XXX and HGF20000 rotary screws. The HG20000 is suitable for electric motor drive.
LeROI gas screw compressors are available in 12 models covering a flow range of 20 (0.4 M3/min) to 15,000 MSCFD (300 M3/Min) and horsepower from 10 (7.46 KW) to 800 (596.8 KW).
Single-Stage high pressure operation from 20 PSIG (1.38 BARG) to 350 PSIG (24.1 BARG) maximum is possible with the HG20 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 (4.13 BAR). Optional oil pumps are available for applications with less than 60 PSI (4.13 BAR) differential pressure.
Discharge porting can be selected 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.
