GE leverages its history of technical innovation to address key environmental issues and to provide current best practices in manufacturing to delivery of its products to customers around the globe. Here you will find an overview of the engineering quality and manufacturing expertise that comprises Roots centrifugal compressors.
Roots centrifugal compressors deliver high Multi-Stage Rotor Assembly IMPELLERS: Offered in many different designs and constructions of several different materials, depending upon the operating conditions and gas being handled. The impeller is statically and dynamically balanced and then oversped to 15% above maximum operating speed. The impeller is then mounted on the shaft with a suitable locking device and the rotor assembly is dynamically balanced.
performance and low maintenance. Standard Labyrinth Buffered Labyrinth Buffered Carbon Ring Double Opposed Dry Gas Seal w/ Buffer SEALS: Air applications use the Standard Labyrinth Seal, while Double Labyrinth, Carbon Ring and Dry Mechanical Seals are used for gas applications. Buffer and suction ports can be provided for additional retention of the process gas. Gas-tight shutoff sealing is also available to ensure gas retention when the compressor is not operating.
