Enhanced Efficiency Through Advanced Technology 

High-Efficiency Steam Paths

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

Advanced Sealing Features

Maintaining radial clearances and sealing 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 proven last-stage blades in our broad portfolio enable optimization of low pressure exhaust for air-cooled, cooling tower, and once-through condenser applications.
