In 1913 the Austrian engineer Viktor Kaplan developed the Kaplan turbine, according to the Francis turbine principle. A typical example of use are fluvial hydroelectric plants.

This turbine is ideal for smaller jumps (from 1 m to about 15 m) and high water flow rates.

The Kaplan turbine is built almost exclusively with a vertical axis, since the optimal flow direction through the turbine is from top to bottom. The incoming water is regulated by the duct, in such a way as to adapt and optimize the efficiency of the turbine to the needs and flow of water. The flow of the diverted water reaches the distribution fins which convey the water on the impeller blades, arranged parallel to the shaft and which in turn transport the energy to the generator. The impeller blades of the Kaplan turbine can be oriented for high energy efficiency.

The design and construction of Kaplan turbines takes place in cooperation with our German partner Watec Hydro. The design and construction of Kaplan turbines can adapt to customer needs. We provide a complete service, from planning to construction, up to installation and maintenance.

The design, the realization and construction of Kaplan turbines has been in cooperation with our German partner Watec Hydro for over 10 years. In recent years we have designed and implemented several jobs using Kaplan turbines, confirming our professionalism and experience in the sector: you can see examples of our work on this page.
