Turbogenerators

ANDRITZ HYDRO is a global supplier of turbogenerators for thermal power plants with output ratings from 10 MVA to 350 MVA.

The turbogenerator center of competence of ANDRITZ HYDRO is organized in a separate division and located in Austria. The historical brand "ELIN" has been integrated into the ANDRITZ HYDRO business area, providing decades of experience and comprehensive know-how. In order to secure high quality and short delivery times, ANDRITZ HYDRO has its own welding and machining facilities for the turbogenerator business.

The product range covers three different areas

  • 10-56 MVA: four-pole design, air-cooled
  • 50-220 MVA: two-pole design, air-cooled
  • 220-350 MVA: two-pole design, hydrogen-cooled
