Features and Benefits

High-Efficiency Steam Paths
Advanced high-reaction and impulse steam path technology ensures high efficiency for any application. To maintain efficient blade and nozzle sealing, integral cover blades with continuous contacting surfaces are used throughout the turbine sections. This allows continuous circumferential sealing and multiple seal teeth at each stage. The integral covers on blades and nozzles provide superior mechanical damping and tip sealing control. 

Advanced Sealing Features
Maintaining radial clearances and seals are critical factors in achieving optimum performance. Our turbines employ a combination of labyrinth, brush, abradable, and active retractable sealing technologies to reduce leakage and control clearances within the steam path. 

Broad Family of Last-Stage Blades
The industry's largest family of last-stage blades enables superior custom configurations.

Lifecycle Product Management 
Reducing the cost of ownership by combining monitoring, diagnostics, and predictive maintenance to minimize outages and maximize run time.
