SGT-400

The SGT-400 is a twin-shaft gas turbine available in two different power ratings for both power generation and mechanical drive applications. The twin-shaft arrangement allows for commonality of parts in mixed-duty installations.

The gas turbine offers the highest efficiency in its power class, incorporating the latest aerodynamic and combustion technologies. With over 25 years of operating experience, the SGT-400 is proven in both offshore and onshore applications.

Over 300 units have been sold with approximately 3 million hours operating experience.

·        Latest aerodynamic and combustion technology

·        Suitable for all climates, onshore and offshore

·        High power-to-weight ratio
