Drive Technologies Drive system supports power generation in Tyrolean mountain hut Clarahütte, a mountain hut located 2,000 meters above sea level in the Tyrolean Alps and owned by the German Alpine Association, will be generating its own hydropower in future using integrated drive technology from Siemens Industry.
Situated close to the Umball Falls in Hohe Tauern National Park in Austria and surrounded by several three thousand meter-high peaks is Clarahütte, run by the German Alpine Association (DAV). This mountain hut is a popular starting point for tours of the glacier and demanding mountain hikes. The hut was due a general refurbishment, partly as a result of damage caused by an avalanche in 2012. The project is executed by the Essen section of the German Alpine Club, mostly as volunteer work. As part of the renovation project, the DAV decided not Instead of a petrol generator, in future, a mill wheel and the nearby river Isel will be the sources of power for the Clarahütte only to modernize the hut itself, but to also invest in a mill wheel power plant to make it self-sufficient with green energy. Instead of a petrol generator, in future the nearby river Isel will be the source of power for the hut. For the mill wheel to turn hydropower into electrical energy requires highly efficient technology. This was supplied by Siemens in the form of an integrated drive system comprising a Simotics M synchronous motor acting as a generator, and a Flender SIG gear unit. The components were provided on site by the Siemens Solution Partner Softwerk GmbH. These compact and rugged drive components interact ideally to create a reliable, high-powered drive train, supplying Clarahütte with its own independent source of energy. This will allow the operators to take care of the many mountain climbers and hikers it hosts every year without impacting on the delicate Alpine ecosystem with added carbon emissions. The refurbished mountain hut is due to open its doors to visitors in the summer of 2014.
