JG / JGA

The JG and JGA are medium-sized, driver-rated separable reciprocating compressors utilized in gas gathering, fuel-gas boosting, underbalanced drilling, and CNG applications.

The JG, first introduced in 1966, was Ariel's entry into the domestic reciprocating compressor market. The first 150 frames built were JG/2 and JG/4 and is still Ariel's smallest compressor available in a four-throw configuration. The JGA offers modern gas lift capabilities as shale well production increase in volume.

Product Features

 

Rugged Crankcase

 

Ariel crankcases are designed for long service life and ease of access during maintenance. They feature a heavily-ribbed, high-strength cast-iron base with a removable, lightweight aluminum top cover. 

High-Efficiency Oil Filters

 

Ariel JG/JGA compressors feature high-efficiency, non-bypassing spin-on oil filters rated at 5-micron nominal and 17-micron absolute.

Durable Pistons and Rods

 

JG/JGA compressors feature wear-resistant steel or gray iron pistons and precision-ground alloy steel piston rods with locking crosshead nuts. Rolled threads are 1/4" under rod diameter for easy installation. 

 
 

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.
