Centrifugal Compressors with Horizontally Split Casing

TECHNICAL DATA

  • Capacity: up to 1 400 m3/min (up to 120,000 Nm3/h)
  • Discharge pressure: up to 45 bar (45,8 kgf/cm2)
  • Drive power: up to 6 300 kW

COMPRESSIBLE GASES

APPLICATION

Compressor system
5GC1-387/12

The casing of a horizontally split compressor consists of a cast cylinder, rotor, a set of embedded parts, seals and bearings. The horizontally split casing simplifies the inspection and repair of the flow path components, bearings, and seals.

The basic models can be modified in accordance with the customer requirements.

DESIGN FEATURES & ADVANTAGES

  • Horizontally split casing in a combination with embedded parts in the flow path allow fabrication of the complex machines for compression of inflammable gases (oxygen) and gases tending to form various sediments along the flow path.
  • Maintenance of bearings and seals without disassembling of the casing
  • Low cost of routine maintenance due to access to the rotor and embedded parts through the upper casing half
  • Special design and materials requirements for compression of inflammable gases
  • Many years of operation in real condition have proven high reliability and efficiency of the construction components
  • Available in customized versions in accordance with customer requirements

INSTALLATION

  • Version for indoor installation inside of a building (enclosure) of a compressor station
  • Hangar version (prefabricated building) including all engineering systems
  • Version for outdoor installation in open air areas
