Two Stage Natural Gas Compressor - HGT17 with Bell Housing and Versatrol
Back to the product list

HGT17 and HGT24 Series Industrial Gas Compressors

LeROI provides rotary screw compressors for gas to the oil and natural gas, and industrial and process industries. Two-stage rotary screw natural gas compressors are very cost-effective for handling high volumes of gas in field gathering, vapor recovery, and a wide range of other applications and delivering gas at high pressures.

The work is divided between two-stages and reduces the forces on rotating elements such as bearings. 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 packings to wear out or cause loss of efficiency. The two-stage LeROI screw compressor line offers the same capacity and power modulation features as the single-stage screw gas air compressors. Versatrol is an available option providing the end user with maximum flexibility.

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 HGT17 and the HGT24 rotary screw. LeROI Rotary Screw Gas Compressors are available in 12 single-stage 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), and four two-stage models covering a flow of 1,000 MSCFD (19.62 M3/min) to 13,000 MSCFD (260 M3/min) and horsepower from 400 (298.28 KW) to 600 (447.42 KW).

Two-stage operation from 250 PSIG (17.2 BARG) to 500 PSIG (34.5 BARG) maximum is possible with the HGT17 and HGT24 Series oil-flooded compressors. Compressor packages are therefore simple, reliable and inexpensive. The gas differential pressure provides oil circulation for proper lubrication. Optional oil pumps are available for applications requiring specific oil regulation. All iron or steel construction with no copper or copper alloys makes these compressors compatible with natural gas, sweet or sour.
