Turbine
Refurbishment
Thanks to continuous further development, our customers benefit from the latest technical solutions. The systems we overhaul are thus even more robust, more durable and more reliable. We refurbish all turbine types and all products up to an impeller diameter of 5.0 m.
The consistent use of 3D design software even in refurbishment and repair, combined with an efficient production planning system, allow for a complete and seamless documentation of the work performed.
