World-class compressors supported by worldwide service capabilities

The full line of API 11P high-speed reciprocating (HSR) compressors provide Economic, Flexible and Reliable solutions to meet your gas compression needs. Our products range from 60 hp (45 kW) to 9,000 hp (6,714 kW), with a variety of piston rod load capacities and frame stroke combinations.

Over 15,000 of our compressors can be found around the globe working in fuel gas boosting, gas lift, CNG fueling, reinjection, gas gathering, and vapor recovery applications - operating 24-hours a day, seven days a week.

Our compressors are designed to be directly connected to reciprocating natural gas engines (720 to 1,800 rpm) and electric motors (750 to 1,800 rpm). A variety of compressor frame strokes allow the compressor to be perfectly matched to the optimum driver.

To address the challenges that our industry is facing, we have added couple-free high-speed, low vibration compressors, namely CFA, CFH and CFR, which assist customers cut capital and operating costs.

In today’s market, customers want wider operating ranges for their equipment. One of the limiting factors in a reciprocating compressor is the degrees of reversal required for adequate connecting rod pin and bushing lubrication. While industry standards require 30 or more degrees of crankshaft rotation for proper pin load reversal, Cooper Machinery Services' M & H series frames' connecting rods don’t have a requirement. Their unique roller bearing design provides full lubrication, regardless of degrees of reversal, which in turn increases the compressors overall operating envelope. This larger operating envelope reduces the potential for catastrophic crank gear damage and subsequent compressor downtime.

The compressors can be equipped with multiple sensors to track oil chemistry, bearing temperature and crosshead vibration to enable asset performance monitoring as well as condition based maintenance and early issue detection.

Our experts can be quickly mobilized to deliver the highest quality of service whenever you need it, anywhere in the world.
