“The reconstruction of the electrical plant in the Maria Waldrast monastery power station was conducted by Mr Daniel Demichiel (Geppert) economically and to our full satisfaction, bringing it to the current state of the art in electrical engineering.
The reconstruction was carried out and completed on schedule, so that we did not suffer any significant losses in electricity supply.
Mr Daniel Demichiel from Geppert is a very patient, competent and pleasant person, who always had an open ear for our requests and wishes.
Thank you again for your excellent work.”

Josef Wallner, Maria Waldrast


“I have known the Geppert company for over 20 years, and it has always been a pleasure to work with them. Our cooperation started in 1994 with the delivery of a double Francis turbine for KW Avouillons of EW SEIC in Gland, Switzerland. This machine was overhauled by Geppert to the satisfaction of the client in 2014, that is, after 20 years of flawless operation; this machinery will undoubtedly continue to produce electricity for decades. In the meantime, several projects have been developed in cooperation with our engineering office, such as Francis weir turbines, development work for diagonal machines, application of our proven water drives for a Geppert Pelton, Francis turbines, as well as safety valves, and use of a Geppert impeller on a Pelton turbine of our design.”
