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.

Product Features

 

Precision Bearing Shells

 

Every Ariel compressor features main and connecting rod bearings that are precision-machined with tri-metal composition.

Versatile Unloading Devices

 

Ariel offers manual, head-end variable volume clearance pockets (VVCP) on most cylinders. Pneumatic suction valve unloaders are available on a limited basis.

Efficient Valves

 

Plate-type valves are designed for modern speeds, utilizing non-metallic sealing elements as standard. Valves are selected to comply with established low-valve velocity standards.

 
 

Materials 

  • Gray Iron Crankcase: Forged steel crankshaft, gray iron crosshead guide, tri-metal main bearing 

  • Ductile Iron Crosshead: Alloy steel crosshead pin 
  • Forged Steel Connecting Rod: Bronze crosshead pin bushing, tri-metal connecting rod bearing, grade 8 stress bolts
 
 
 

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.
