Rotary screw compressors are very cost-effective for handling high volumes of gas in field gathering, vapor recovery, and other applications. The HG17, HGF17, HGS17 and HGFS17 series are suitable for applications to 180 BHP and 350 PSIG discharge pressure.
Low maintenance and high reliability are inherent with rotary screws because they have few moving parts. There are no valves, rings nor 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 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.
The HG17, HGF17, HGS17 and HGFS17 Series can be direct coupled to engines and electric motors (HG17000 electric motor drive only) for maximum flexibility at minimum cost. The HGF17000 and HGFS17000 compressor shaft bearings can absorb V-belt side load without additional pillow block bearing supports.
Single-Stage operation from 20 PSIG to 350 PSIG maximum is possible with the HG17 series oil flooded compressors. Compressor packages are therefore simple, reliable and inexpensive.
Gas differential pressure provides oil circulation for proper lubrication at differential pressures over 60 PSI. Optional oil pumps are available for applications with less than 60 PSI differential pressure.
All 175mm compressors are equipped with LeROI’s adjustable Vi, allowing field adjustment of internal compression during operation. Also, fixed discharge porting can be ordered to match the internal compression needs of your application.
All iron or steel construction with no copper or copper alloys makes these compressors compatible with natural gas, sweet or sour.
