Turbines applied in large power range, sub critical or super critical steam conditions. Leading edge technology, both in mechanical and aerodynamic design ensures the best efficiency and reliability, in USC configurations if requested for coal / fossil fired plants and in sub critical one for combined cycles as well. Full arc admission and full reaction blading. This configuration is made by an AS module for the High Pressure Turbine plus one single (MS) or double flow (MD) intermediate pressure module plus one (DL) or more (ML) double flow Low Pressure Elements.
