Higher availability and less technical complexity: the StreamDiver’s compact and modular design and its maintenance-free operation minimizes your project costs.
THE VOITH STREAMDIVER –
VERSATILE, ENVIRONMENTALLY-FRIENDLY, ROBUST AND AFFORDABLE SOLUTION FOR THE LOW-HEAD SEGMENT
HORIZONTAL PROPELLER TURBINES FOR LOW HEADS Voith offers five standard modules and two XL modules for heads of 2-8 metres and flow rates of 2-12 cubic metres per second. In order to select the best solution and the ideal number of turbines it is necessary to consider the conditions in which the set-up will be working, the annual flow rate, head range, and the various physical restrictions on site. Ultimately, the overall size of the StreamDiver depends on the module chosen and the minimal water depth below the surface. Voith of-

lthough hydroelectric power accounts for the largest single share of world’s renewable energy production, there is still plenty of unexploited potential in the concept of small-scale hydropower plants. Previously, this means of generating electricity was considered commercially unviable. Since the market launch of the StreamDiver, Voith has delivered 31 machines to satisfied customers in eight countries. Where conventional turbines are no longer considered profitable, Voith’s technology can be used in the form of a compact propeller turbine. StreamDiver is an almost silent and invisible power plant that requires a minimum of construction logistics. As well as being environmentally friendly, and easy to install – so it can be retrofitted into existing transverse structures, in contrast to other machines the StreamDiver also offers the benefit of long maintenance intervals of over ten years.

In 2009, VOITH cooperated with Verbund, the Austrian energy provider, on the development of the StreamDiver, now a well-established solution for the hydropower market. What has made it so special was the concept of standardised sizing from the very beginning. VOITH’s patented technology was created according to the credo: ‘Minimise complexity – minimise breakdowns’ - keep investment and running costs low.
