Natural Gas Compressors
QSG Rotary Screw Gas Compressor
A rotary gas compressor also operates via positive displacement. It contains a pair of helical screws that drive the gas into a chamber. The screws simultaneously shrink the chamber, which forces the compression. Rotary screw compressors are known for their compact yet robust design and construction, as well as their reliability. However, rotary screw compressors are not suited for a dirty operating environment, and the rotary compressor’s life expectancy is typically shorter than that of a reciprocating model.
- 16 models to 600 hp
- Flows to 4.0 MMSCFD
- 130,000 hour design life
QRNG Reciprocating Gas Compressor
A reciprocating gas compressor uses crankshaft-driven pistons to provide compression. The thrust is provided by a positive displacement pump that moves the gas through the system and enhances the gas’s pressure and density. Benefits of reciprocating gas compressors include their ability to produce high power and high pressure compressed gas, as well as the absence of an oil carryover problem. Reciprocating compressors also generally require a lower initial investment than other compressor types.
- 2-34 hp
- Single & Two-Stage
- 400 psig max discharge
