New Pratt & Whitney parts promise 8 MW more, 32,000 hours

PW Power Systems, Inc. (PWPS), a group company of Mitsubishi Heavy Industries, Ltd. (MHI), has announced an upgrade for the 7F fleet parts. The 7FA.03+ suite of parts offers a flexible alternative.

PWPS designs are not replicas of OEM products, but "improved" versions based on extensive repair history. PWPS has reviewed many engine-run product distress modes through the use of thermal imaging, stress analysis and component modeling, and has engineered solutions to reduce or eliminate these factors. The previously improved PWPS re-engineered 2nd and 3rd stage components are combined with the new 1st stage design to achieve the upgraded package. The flexibility options to customize service interval and/or power increase are tailored to benefit the owner/operator. This offering provides an 8 MW increase at the 32,000 hour operating interval.  It can also extend the life or extend service intervals without the power increase based on customer needs.

PWPS delivers customer satisfaction and confidence that is unparalleled in the industry, built on the accumulation of over three million hours of trouble-free service in the field.

BackgroundPWPS designs and manufactures alternatives to OEM-sourced, large-frame industrial gas turbine (IGT) components. The design criteria and quality controls are derived from standards applied to aerospace engine development. Every design feature includes proprietary alloys and coatings to deliver durable and reliable new IGT parts that exceed customer expectations.
