The proven SGT5-4000F gas turbine has a robust design with internal cooling air passages for trusted long-term operation and fast start-up capability.

The advanced annular combustion chamber with individually replaceable heat shields allows for easy and fast walk-in maintenance. Hydraulic Clearance Optimization (HCO) reduces clearance losses to increase the gas turbine efficiency and minimize degradation at start-up and shut down.

Today, around 340 turbines have been sold. The installed fleet has accumulated an impressive fleet experience of 12.5 million equivalent operating hours, and a fleet reliability of 99.2%.

·        Proven design, large fleet experience

·        Easy maintenance, high availability

·        High operational flexibility.
