Engine Repair Facility


Centrax Gas Turbines has over 50 years’ experience providing gas turbine generator service and maintenance. Our Centrax Engine Repair facility was established in 1995 to enable in-house repairs and turbine overhauls to be conducted on the Siemens Energy 501-K gas turbine.

Customers purchasing 501-K-powered generator sets became focused on the through-life costs and the requirement for Comprehensive Maintenance Contracts (CMC’s). Building the dedicated Centrax Engine Repair facility at our Newton Abbot plant has enabled us to keep maintenance costs to a minimum, whilst ensuring the quality of this maintenance remained at the high level of quality our customers expect from us.


Our experts have a wealth of technical knowledge to support the range of Siemens Energy 501-K gas turbine engines. In addition as a service to the Customer, Centrax will monitor the running of the engine following the return to service, to ensure maximum turbine performance and efficiency.

As an experienced Siemens Energy 501-K engine repairer, Centrax can offer advice and support at all stages of the engine repair/overhaul process:

  • The Centrax Engine Repair facility provides support to our contracted fleet, our spare engine-owned fleet and also external customers requiring the facilities we have to support their engines
  • We are able to test all 501-K derivative engines in one of our dedicated engine test facilities in Newton Abbot including DLE emissions tests where required
  • Centrax continues to work closely with Siemens Energy in the research and further development of the 501-K engine derivatives in particular the 501-KB7S DLE model
  • In-house strip-down, build and re-assembly
  • Centrax provides new Siemens Energy OEM parts

Centrax supplies and builds the 501-K boost module for Siemens Energy which is also fitted to the 501-KB7 and 501-KB7S derivatives; over 300 boost modules have now been assembled at Centrax.

Centrax also maintains an extensive 501-K gas turbine engine rental fleet to support our customer base.
