Superior high speed engines
IN DEPTH EXPERTISE, CAPABILITIES, AND PARTS INVENTORY
Cooper is the O.E.M. for separable high-speed Superior engines and compressors. Our aftermarket team delivers total aftermarket support for Superior engines and compressors, from parts, to machine shops, to engineering, to field support — all from one convenient and very attentive source.
Cooper’s turbocharged Superior™ gas engines are built for reliable, continuous, heavy-duty service. Ideally aligned with our extensive Superior™ reciprocating compressor portfolio in terms of speed and horsepower, these engines can provide lower fuel consumption, increased efficiency, lower emissions, and a service life that surpasses that of many other engines in the marketplace.
Available in 12- and 16-cylinder models, these exceedingly robust engines were designed from the ground up for operation on natural gas and even dirty gas. Superior™ gas engines offer optimized fuel/air mixing and timed fuel injection, resulting in reduced fuel consumption requirements. The engine’s low compression pistons reduce dynamic stress for more stable, reliable operation.
Cooper provides dedicated support to its Superior engine customers with new O.E.M. spares parts, repair and UX parts, “zero-hour” remanufactured and UX engines, field services, and numerous upgrades to improve engine performance and reduce emissions.
Genuine O.E.M. Cooper parts for Superior high-speed separable engines and compressors are backed with decades of engineering, manufacturing, and in-field experience in material wear. We provide spare Superior parts that are manufactured to the latest standards and technical advancements. From our Superior parts manufacturing centers in Houston and Deer Park, Texas, we are committed to making every Superior part with our own brand of O.E.M. quality and to O.E.M. standards. We are committed to stocking and delivering Superior engine and compressor parts to our customers quickly and efficiently, and that’s why we house thousands of Superior part numbers at our dedicated central distribution center in Houston Texas, our Superior center of excellence in Deer Park, Texas, and in our field locations around the world.

EXCEPTIONAL QUALITY & ABSOLUTE DEPENDABILITY
A Rich Legacy
In 1889, Patrick J. Shouvlin opened a small machine shop in Springfield, Ohio. With the natural gas engine in its early beginnings, Shouvlin began his quest to develop his own model of natural gas engine. By the 1890’s, Shouvlin’s company became known as the Superior Gas Engine Company, which described the product offered during this time “Superior”.
Although Superior engines were initially designed for oil field applications, the company soon developed a relationship with the National Supply Company to market its engines throughout the United States.
By 1920, the Superior Engine Company added a semi-diesel engine. In 1923, it purchased Otto Engine Works to increase its market position and market share. The first Superior vertical diesel was completed in 1926 and the company changed its name to the Superior Engine Company.
