Introducing Ormat’s between-bearings turbine

INCREASING PRODUCT LIFE AND PERFORMANCE WITH CUTTING-EDGE TECHNOLOGY

By Alex Katz

We are proud to introduce our new, high-performance between-bearings turbine, yet another step towards our vision of a sustainable, renewable energy future.

Utilizing the traditional radially split design, the turbine rotor in the new product is supported between the axially spaced bearings. The new design offers the best of both worlds. Maintaining the radially split design optimizes high temperature and pressure management while keeping costs to a minimum. The between-bearings rotor Enhances rotor durability, increasing the product life of the bearings and improving the power output from a single turbine by up to 50% when compared to the overhang design.

Ormat’s between-bearings turbine design is field-proven, with over 25 turbines already in operation globally. It operates with up to five expansion stages, for maximum performance and efficiency.
