ARIEL JGH & JGE Gas Compressor

prod_JGH These larger size separable, reciprocating, gas gathering compressors are found by the thousands in gas fields throughout the world. They are engineered to accommodate a wide range of compressor cylinders. Driver rated, they pair well with modern, high-speed engines and work year after year as one of the most cost effective choices for rental fleets.

As with all Ariel compressors, regular, minimal maintenance insures a lifetime of continuous, trouble free operation.

Features

Serviceability	Entire unit is designed for ease of repair. All components are readily accessible.
Standardization	Many components are interchangeable throughout the various lines.
Full Pressure Lubrication	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 packings. Stainless steel tubing is used throughout the cylinder lubrication system.
Unloading Devices	Manual head-end variable volume clearance pockets, pneumatic fixed volume clearance pockets, and pneumatic suction valve unloaders are available on most cylinders.
Heavy Duty Crankshaft	Forged steel, precision machined with integral counterweights.
Rugged Crankcase	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 Bearing Shells	Precision-machined, tri-metal main and connecting rod bearings.
Rugged Crossheads and Guides	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.
Rigid Connecting Rods	Forged steel (JGE) or ductile iron (JGH), four bolt, heavy duty "H" section.
Quiet Auxiliary Drive	Fully enclosed and continuously lubricated chain drive adjusted by positive positioning eccentric vernier.
Oil and Dust Seal	Foolproof, non-contacting crankshaft oil seal, plus reliable non-wearing dust seal.
Proven Cylinder Design	Non-cooled compressor cylinders with ample nozzles and large gas passages. Cylinder bodies are ion-nitride hardened and drilled for indicator ports.
High Strength Bolting	Grade 8 or 17-4PH bolting on all pressurized components. All bolting designed for accessibility.
Efficient Valving	Plate-type valves designed for modern speeds utilizing non-metallic sealing elements as standard. Selected to adhere to established, low valve velocity standards.
Durable Pistons	Wear resistant ductile or gray iron pistons, with wear bands or rider rings.
Stout Piston Rods	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.
