ARIEL JGC & JGD Gas Compressor
These large, medium speed reciprocating separable compressors were designed to pair with electric motors and natural gas engines recently available for compression units (packages) and are already proven as one of the most cost effective methods of compression for pipeline transmission, power generation, refrigeration, processing and all other applications requiring large horsepower drivers and compression capacity.
Cylinders, specifically for pipeline transmission (CL & DL) are available, as well as a full range of cylinders for all other applications. The demand for the JGC and JGD has remained very strong since their introduction to the gas transmission market . As with all Ariel compressors, regular, minimal maintenance insures a lifetime of continuous, trouble-free operation.

Features
| Entire unit is designed for ease of repair. All components are readily accessible. |
| Many components are interchangeable throughout the various lines. |
| A frame-driven lube oil pump provides pressurized, cooled oil through a full flow oil filter to all moving parts in the frame. A divider block distribution system supplies metered oil to cylinder bores and rod packing. Stainless steel tubing is used throughout the cylinder lubrication system. |
| Manual head-end variable volume clearance pockets, pneumatic fixed volume clearance pockets, and pneumatic suction valve unloaders are available on most cylinders. |
| Forged steel, precision machined with integral counterweights. |
| Heavily ribbed (with spacer bars for stiffening), high-strength cast iron base with lightweight aluminum top cover and removable end covers for ease of access. |
| Precision-machined, tri-metal main and connecting rod bearings. |
| Cast iron crosshead guides with external ribbing and removable side covers. One piece, long life crossheads with direct, full pressure lubrication at top and bottom for minimum wear. Hardened and ground steel crosshead pins. |
| Forged steel, four bolt, heavy duty "H" section |
| Fully enclosed and continuously lubricated chain drive adjusted by positive positioning eccentric vernier. |
| Foolproof, non-contacting crankshaft oil seal, plus reliable non-wearing dust seal. |
| Non-cooled compressor cylinders with ample nozzles and large gas passages. Cylinder bodies are ion-nitride hardened and drilled for indicator ports. |
| Grade 8 or 17-4PH bolting on all pressurized components. All bolting designed for accessibility. |
| Plate-type valves designed for modern speeds, utilizing non-metallic sealing elements as standard. Selected to adhere to established, low valve velocity standards. |
| Wear resistant ductile or gray iron pistons, with wear bands. |
| Short, stiff, precision-ground alloy steel piston rods with locking crosshead nut. All piston rods are ion-nitrided for surface hardness and longevity. Rolled threads are 1/4" under rod diameter for easy installation through packing. |

Cylinders
The long standing basis of Ariel's successful design philosophy is research showing that modern, moderate and high speed compressor cylinders do not require internal water cooling passages. The absence of water jackets results in larger gas passages, reducing pressure-drop losses and yielding the high efficiency Ariel cylinder for the same sized cylinder casting. The proven design of the Ariel cylinder eliminates the cost of the cylinder cooling system and the major maintenance problems associated with water cooling, such as scaling and corrosion.
Most Ariel cylinders are ion-nitrided, increasing surface hardness and reducing cylinder bore wear to an absolute minimum. Ariel cylinders, combined with the innovative design of every Ariel frame, have earned Ariel the reputation for the lowest operating and maintenance costs of any gas compressor available today.
