Reliable Solutions. Service-Oriented.

All parts required for re-assembly are not always identified during the opening

inspection of a turbine-generator outage. Late-stage discovery of required parts

can make effective sourcing a challenge. You need the right part, the first time,

at a fair price. We understand the critical path and provide excellent quality,

delivery and competitive pricing of turbine-generator components that meet or

exceed technical specifications, the first time.
