clark integral engines
& compressors
For decades, Cooper has been a complete provider of parts, service, repairs, and upgrades for Clark integral engine-compressors.
clark integral engines
Large-bore two-cycle integral engine compressors compress natural gas more efficiently than today’s high-speed reciprocating separable compressors and turbines. A slower speed allows Clark products to work for decades. When they do finally need service or repair, Cooper delivers the quality parts and expert service needed to quickly get them back up and running.
Cooper delivers a full line of O.E.M.-quality parts, service, repairs, and technical support to customers who want to keep their integral gas engine-compressors running in peak condition. We provide O.E.M. quality and modernized power cylinders, liners, pistons, heads and more for your Clark slow-speed integrals.
Genuine Cooper parts for Clark engines are backed with decades of engineering, manufacturing, and in-field experience in material wear. We provide spare Clark engine parts that are manufactured to the latest standards and technical advancements. We are committed to making every Clark part with our own brand of O.E.M. quality and to O.E.M. standards. We are committed to stocking and delivering Clark engine parts to our customers quickly and efficiently, and that’s why we house many key Clark iron parts at our dedicated central distribution center in Houston, Texas and in our field locations around the world.
Cooper maintains a large inventory of Clark O.E.M.-quality cylinder heads, cylinders, liners, pistons, bearings, and pins that can be shipped within 24 hours. For any other parts, we have experienced shop personnel to repair and restore product to O.E.M. specifications.
Cooper has provided a complete line of engine, field, and shop services for Clark integrals for decades. From preventative maintenance, to shop and field overhauls, to field machining, to repairs in our many global shops, our Cooper service teams are fully trained on the brand engines & compressors and stand ready to assist our customers with all their service needs.
For decades, Cooper has been providing technology and engineering services for Clark engine upgrades. With our advanced technologies, expertise, and project management experience, we offer Clark upgrades to reduce engine emissions, increase horsepower, improve efficiencies and reliability of your equipment, and reduce maintenance costs.
To further strengthen our upgrade portfolio for Clark engines , Cooper acquired HOERBIGER’s Engines Services (HES) division in 2019. Cooper now offers even more upgrade technologies including the HyperFuel System TM, HyperBalance™, HyperLogic™, ePCC™, and ePFI™. The Engine Services team offers engine emissions reduction and efficiency improvement upgrades, applicable to all types of Clark integral engines.
The Houston, Texas facility is a trusted repair and field service provider and acts as Cooper’s center of excellence for Clark, Ingersoll-Rand, and Worthington product lines. It provides repair of Clark Engine & Compressors, Ingersoll-Rand, Worthington, and Cooper-Bessemer power liners, cylinders, and pistons.
The roots of Cooper’s involvement with Clark after-sale support began in 1915 when the son of an American Civil War soldier started his own auto repair and motor-rebuilding business in Ponca City, Oklahoma. Clair Nickles’ auto business grew and evolved into Nickles Industrial and expanded to include large engine repairs and manufacture of replacement parts for engine brands such as Clark, Ingersoll Rand, and Worthington. The company evolved into the nation’s largest independent manufacturer of replacement parts of large stationary gas and diesel engines. The business was sold to the Cameron International Compression Group (today’s Cooper) in 2001. For 20 years, Cooper has upheld the legacy of Clair Nickles, and today, provides owners of Clark, Ingersoll Rand, and Worthington engines a complete line of after-sales support including parts, repairs, service, and technical support.
