​Refurbishment of Francis Turbines

​Depending on the type, the refurbishment of Francis turbines extends over different production technologies. Whether a spiral turbine with rather small impellers or large, low-pressure turbines with very large dimensions - we are optimally equipped for all sizes up to an impeller diameter of five meters and possess the know-how for both repairs and partial component re-production.
