    REHARTPOWER in Deutsches Museum

    As part of the general refurbishment of Deutsches Museum in Munich the exhibition “Energietechnik/Kraftmaschinen” [“Energy technology/Prime movers”] will also be modernised. The curator in charge asked us, as manufacturers of hydropower plants REHART GmbH, if we could provide two exhibits for this. After a short internal discussion we quickly decided that this would be an ideal project for our trainees.Under the supervision of Frank Schiwietz, Hydropower Division Manager at REHART, this exciting and unusual task was assigned to four trainees who dealt with the entire project on their own accord – from planning, design and purchasing to production. The result is: two models, one on a scale of 1:12 comprising a hydropower screw and fish migration screw (FAS) and another one of a single hydropower screw on a scale of 1:10. Contrary to the original, the FAS in the model has a transparent tube so that the inner screw is visible. The main challenge was the small dimensions and the low material thicknesses, since REHART usually thinks and works in larger dimensions. Despite the obstacles they had to face, all involved did an excellent job and we got two wonderful exhibits which will give the museum visitors a very good impression of the a “small hydro power station” and the structure and operation of our plants. As technical product designers, Lena Offinger and Jacqueline Ortner, were responsible for the planning, construction and the communication with Deutsches Museum. Johannes Fackler, metal constructor took care of the cutting and welding and Patrick Unfried, as a cutting machine operator, supplied the required turned parts.The official handover of the models to Deutsches Museum took place on 30 July 2020 by Lena Offinger and Jacqueline Ortner in Munich. However, before the visitors can see the new exhibition space with the models by REHARTPOWER, there will be a lot of water under the bridge - or flowing through our hydropower plants. As things are today, the area will perhaps be accessible as of winter 2021/22, the renovation of the museum may even last until 2028.

  • Anuj Motghare

    Route: Ehingen - India - Berlin - Ehingen

    When Anuj Motghare completed two internships at REHART in Ehingen in 2014 and 2016, no one could foresee that he would return to Ehingen in 2019 with a "detour" via Berlin. From 2012 to 2016, he worked as a senior engineer in the "Design and Development" department at our partner company, Jash Engineering Ltd. in India, where he gained initial experience in the field of hydropower. This was followed by an MBA in "Sustainability and Energy Efficiency" at the TU Berlin, which he successfully completed this year. The good experience and contacts from his internship period took him back to Ehingen in Middle Franconia, where since 1 July he has been supporting our hydropower team in the area of design and development. We are pleased about this gain to our REHARTPOWER line-up, and hope that after the big city life in India and Berlin, he will soon settle in and feel at home in our rural surroundings.

    You learn from your mistakes

    REHART replaces faulty hydropower screws. With much excitement, the largest hydropower plant built by REHART, the Hausen hydropower plant, went into operation in summer 2011. The plan was that two screws with a diameter of 3.4 meters each and a total output of 500 kW use the power of the water in the Black Forest to generate environmentally friendly energy.The plant has done exactly that over the past 8 years. However, after some 5 years of operation, it turned out that the weld seams on the screw coils in the outlet could not hold up to the large loads. Cracks formed and the coils were damaged by the massive forces acting there. Following extensive tests and expert reports, it was possible to prove that this had been caused by errors in the design of the screws and poor workmanship in the welding work. “Back then we made a mistake - partly due to the lack of experience," admits Klaus Schülein, Managing Partner of REHART GmbH. "However," Schülein continues, "we admit our faults and therefore replaced both screws after almost 9 years of operation at no expense for our customers. Over the years we have since learned a lot and know that the new screws no longer have this defect and that the system will continue to work profitably for our customers after the replacement!” The calculation of the new screws was checked by external experts. In addition, REHART GmbH is now certified according to DIN ISO 9001:2015, is a certified welding specialist in accordance with the requirements of DIN EN 1090-1/-2, and the employees entrusted with the welding work have the best qualifications.Under the REHARTPOWER brand, REHART has built more than 125 hydropower plants and continuously improved and optimized both the design and the production processes. In conjunction with FAS (fish migration screw system REHART/Strasser) the plants guarantee the officially required passability of flowing waters in both directions and make a valuable contribution to environmentally friendly energy generation.
  • The trade show team in Japan

    Hydropower in the capital of Japan

    In March 2019 the 11th GWPE (Global Warming Prevention Exhibition) exhibition took place in Tokyo/Japan. With more than 100 exhibitors and ca. 100,000 visitors, GWPE is the largest exhibition for environmental protection and renewable energies in the Asiatic region and therefore an important rendezvous for the sector. That’s why Thomas Böttcher, member of the REHART hydropower sales team, was on site to answer the questions of the interested trade visitors. With ca. 400 visitors at the stand of “Japan Small Hydropower Co., Ltd.” our Japanese representation was able to chalk up a success. Since the hydropower sector is still new territory for our Japanese colleagues, the Mr. Böttcher’s support was invaluable and very important. Now we look forward to seeing how interesting projects for REHARTPOWER will be developing in the Asiatic region.
  • Philipp and Klaus Schülein

    Let the children take command ...

    In his hit “Kinder an die Macht” in 1985, the German singer, Herbert Grönemeyer was heard to sing the praises of giving “power to the children”. Klaus Schülein, Managing Partner of REHART GmbH, has followed this piece of advice and appointed his son, Philipp as Managing Director of REHART GmbH as of 01.01.2019. This change at management level was announced to the staff at the Christmas party where Philipp, to enthusiastic applause from his fellow workers, was presented with his new business cards citing him as “Managing Director”. This step means the “next generation” is taking on even more responsibility in the successful family-run enterprise and will play a decisive part in shaping the future fortunes of REHART.
  • fish migration screw next to the hydropower screw

    Patent extended to Turkey

    Our solution to position a fish migration screw next to the hydropower screw has now also been patented for Turkey. This structure enables us to decouple the power generation completely from the ascending system. This way, all parameters can be optimally adapted in both sectors to meet the respective requirements. REHART GmbH has now been granted the patent certificate (TR2016/14873T4) by the Turkish Patent Office for the solution, which has been protected by the European patent EP2735728 for some time now.
  • guests from Estonia

    An enthusiastic delegation from Estonia

    A short while ago REHARTPOWER hydropower station in Pilsing, Lower Austria, was visited by top-level guests from Estonia. The delegation of representatives of the Estonian Ministry of Environment and the University of Life Sciences, arrived with the objective of getting to know the new fish ladder technologies to be able to install these in their home country. The fish migration screw FAS (system REHART/Strasser) by REHARTPOWER won over the participants completely. The guests not only got inspired from the combination of a safe fish descent via the hydropower screw and ascent via FAS, but also by its actual functionality. During the short visit at the plant the ascent of 16 different kinds of fish could be counted at the FAS. We are looking forward to planning and realizing many interesting projects in Estonia.
  • Hydropower in France

    Hydropower in France

    What we call a “small hydropower plant” is also a very interesting subject for our European neighbors in France, which is why REHART participated in the trade fair “Rencontres France Hydro Électricité” for the first time. In Toulouse from June 29 – 30, 2017, approximately 550 specialists and people simply interested in hydropower got together to get the latest information on new products and possibilities of hydropower.The FAS (fish migration screw system by Rehart/Strasser) was of particular interest among the visitors, and the successes already achieved here even surprised the trade visitors. Our team was able to make many useful new contacts and was very positive about their participation. “REHART was a new name for many of the visitors, but our concept was very convincing and I think it certainly won’t be the last time we were present at this trade fair,” was how Philipp Stadler from our REHART POWER team summed it up.
  • The water lifting screw shortly before transport

    1005 liters per second

    In future this considerable volume of wastewater will be pumped per second in a wastewater treatment plant in the Gütersloh region by the largest tubular lifting auger ever built by REHART. In contrast to “normal” pumps, foreign particles contained in the wastewater are not a problem for this auger with a length of nearly 9 meters. Therefore, this technology is often used for pumping wastewater. At present the “blue giant”, equipped with a weather protection hood, is being assembled and will be delivered soon to its destination at the wastewater treatment plant.
