GE’s DH-series compressors provide best-in-class reliability in downstream applications including recycle gas in polypropylene, polyethylene, and ethylene oxide plants, plus heat pump and booster services in petrochemical plants and refineries. After more than 50 years, they remain the industry’s design benchmark — in fact, new models from other OEMs are still based on our early designs.
Ruggedly built in accordance with API 617 Chapter 2, our vertically split, centrifugal barrel design delivers excellent performance in a variety of medium-pressure applications. The single-stage, overhung configuration simplifies maintenance and ensures low costs for repairs and spares over the entire lifecycle. For example, shaft bearings can be replaced simply by removing the top half bearing cover; and a rear pull-out allows easy inspection of the shaft seal and impeller without disturbing the process piping or main compressor casing joint. The impeller is fixed to the shaft with hydraulics to allow simple removal and re-installation without heating.
An impressive mix of standard features drives efficiency and performance, while a wide range of options enables customization for any operating conditions. Every process licensor has its own unique compressor requirements — and GE has the proven designs, fleet experience and engineering expertise to meet them all. We continually invest in research and development to improve design characteristics and materials. The GE Center of Excellence for motor-driven compressors in Le Creusot, France, has the manufacturing capability for projects and units of all sizes.
