The Ariel JGN / JGQ
Small Line
JGN / JGQ
A workhorse in field-gas applications, these separable reciprocating compressors are engineered to pair with high-speed engines effortlessly. Available with high-pressure cylinders, the JGN and JGQ are excellent choices for gas-lift and CNG vehicle-fueling applications.
Customers may choose to build their small horsepower rental fleets with the JGN and JGQ for three-stage configurations applications. The rugged characteristics in these two frames (250-280 BHP) provide operators the strength to handle demanding field gas conditions. The JGN and JGQ offers access to a variety of capable valves and unloaders, providing versatility as field conditions change.

Innovative Cylinders
Ariel produces versatile cylinders that can be utilized over wide pressure ranges without compromise by using valves that effectively balance reliability and performance. For each compressor frame size, Ariel's lineup of cylinders can fully utilize that frame's horsepower and rod load capabilities. Cylinders can be combined in hundreds of different configurations to deliver the precise volume and pressure of gas required.
Ariel 7 Performance Software is used by Ariel engineers and industry experts to model and design compressor configurations for their specific application. All of our cylinder designs, past and present, can be accessed to duplicate your existing compressor operations or design a new build.
