Detachable rotor bundles

They are intended for re-equipment of existing fleet of gas transfer turbo-compressor packages

  • at booster compressor stations to provide stable gas production under conditions of intensive bed pressure decreasing on the final stages of fields development;
  • at gas main compressor stations of gas mains to optimize their modes of operation;
  • at underground storage (UGS) for efficient equipment application under conditions of varying modes of gas discharging/injection.

Detachable rotor spchbundles comprise compressor rotor and stator parts installed instead of standard ones at site of gas transfer turbo-compressor packages operation.
