New Gemini separable high-speed gas compressors from Cooper are rated 60 hp to 800 hp (45kW to 597 kW). They provide customers unsurpassed service for applications such as fuel-gas boosting, gas gathering, gas lift, CNG, and pipeline and storage-withdrawal applications.
1. Popular
- Cooper offers a full line of high-speed reciprocating compressors, ranging from 60 to 800 hp (45 kW to 597 kW) with a variety of piston rod load capacities and frame stroke combinations.
- Over 10,000 compressors can be found around the globe, working in gas boosting, gathering, lifting, fueling, and injecting applications
2. Economical
- Global network of distributors.
- The compressor fits on a single skid, simplifying moves and lowering installation, site construction, and re-application costs.
- Field-replaceable cylinder liners allow the cylinder bore to be increased or decreased as needed.
- A variety of capacity control devices are also available to ensure horsepower is not wasted.
- Modular design of Gemini high-speed reciprocating compressors allows frames and cylinders to be matched and re-arranged with only minor changes to the skid
3. Reliable
- Designed to operate 24 hours a day, seven days a week.
- Gemini high-speed API 11P reciprocating compressors use a balanced-opposed design to minimize vibration by equalizing the opposing reciprocating forces on the crankshaft.
- Heavy, ribbed frames distribute reciprocating stresses evenly for greater strength and longer life.
- Many compressor cylinders are water-jacketed to lower operating temperatures, provide thermal stability, and improve valve life.
