Planning Ahead: EthosEnergy’s Rotor Solutions for Frame 7FA Units

As Frame 7FA gas turbine units approach or exceed 144,000 fired factored hours (FFH) or 5,000 starts (FFS), operators face critical decisions to maintain reliability and performance. With supply chain constraints, material shortages, and a growing number of F-Class rotors nearing end of life, proactive planning has never been more important.

EthosEnergy’s 7FA rotor solutions – from new rotors to lifetime extension options – are designed to meet these challenges head-on.

Our new rotor solution, available through exchange or fleet programs, aligns with all relevant TILs. EthosEnergy’s advanced re-engineering approach, which combines material characterization, predictive modeling, and state-of-the-art manufacturing, ensures exceptional quality, durability, and compliance.

This white paper explores the development, benefits, and implementation of the new 7FA rotor, providing operators with the insights needed to plan effectively and safeguard long-term operational success.
