Spare parts and component repair

We retain over 70,000 items of minor parts, along with major components that can be offered for Service Exchange. Additionally, we have capability to store and manage customer's own parts.

We supply genuine OEM package part replacements which have been engineered and checked against our extensive records, to match the build of your turbine. All parts supplied carry a full OEM warranty.

In addition to our extensive stock holding, we use the latest repair technologies to bring components back to a 'zero-hour' condition.

We have exclusive use of the intellectual property rights and are the appointed technical authority for the GEC Gas Turbine Fleet.

This allows us full access to the original drawings and technical data to investigate and source suitable replacements or alternatives from other sources.
