Description
The next generation of advanced air-cooled gas turbines
Our HL-class gas turbines are paving the way to the next level of efficiency and performance.
Our HL-class gas turbines are paving the way to the next level of efficiency and performance. Derived from proven H-class technology in an evolutionary development step, the next generation of advanced air-cooled gas turbines uses a series of new, but already tested technologies like super-efficient internal cooling features for blades or vanes and an advanced combustion system to increase firing temperature.
The result:
A technology carrier to the next level with a combined cycle efficiency beyond 64%, with a midterm goal of even higher efficiencies. The HL-class consists of two engines: The SGT5-9000HL for 50 Hz, and the SGT6-9000HL for 60 Hz.
Efficiency, flexibility and hydrogen capability are key levers in driving the decarbonization of the energy industry – which also makes the HL-class a future-proof gas turbine.

Personal reflections after one year of testing: “I would be lying if I said I didn’t hold my breath during that first start-up a year ago. In some ways, it felt like I was holding my breath for five years, building up to that moment. What a thrill it was to see all burners lit up, the first time we tried
