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 HG12 and HGF Series are suitable for applications to 125 BHP (89.5 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.
Natural gas engine or electric motor drives are equally acceptable with rotary screw gas air compressors.
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).
The HG12000 can be belt driven or directly coupled to electric motors for maximum flexibility at minimum cost. The compressor shaft bearings can absorb the belt side load without additional pillow block bearing supports up to 50 HP (37.3 KW). Models HG12XXX and HGF12000 are suitable for direct coupling to engines and electric motors.
Single-Stage high pressure operation from 20 PSIG (1.38 BARG) to 350 PSIG (24.1 BARG) maximum is possible with the HG12 and HGF Series oil-flooded natural gas compressors. Compressor packages are therefore simple, reliable and inexpensive.
The gas differential pressure provides oil circulation for proper lubrication at differential pressures over 70 PSI (4.82 BAR). Optional oil pumps are available for applications with less than 70 PSI (4.82 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.
