Our company

Welcome to

The Kaplan turbine - patented by the Austrian engineer Viktor Kaplan in 1913 - is a further development of the Francis turbine. Characterised by its axial inflow with adjustable runner blades the Kaplan Turbine is particularly applicable for hydro-power plants with low heads (up to max. 40 m) as well as large and varying flows.

WATEC-Hydro GmbH is one of Germany's leading companies for Kaplan turbines, based in Unterallgäu, Bavaria. We manufacture highly advanced vertical-axis Kaplan turbines (shaft turbines) with runner diameters from 0.4 m to 2.50 m for our customers, offering comprehensive Know-how for the successful implementation of a wide range of hydropower projects throughout Europe. Over 20 years of experience and more than 330 satisfied customers of WATEC-Hydro speak for the product.

In addition to the new construction of small hydropower plants in the power range from 10 kW to 1,000 kW, we have also specialised in the reconstruction or modernisation of hydropower plants. Furthermore, in addition to formwork construction, we can also offer hydraulic steel components as well as control- and regulation technology and laser-measurements to customers. Through continuous further development and optimisation of our turbine products, we always offer the best complete solution for the specific hydropower site.

We are at the Renexpo Interhydro 2024!

You will find us at stand 107, we look forward to your visit!

The Winter family has already purchased several machine sets (turbines, generators and automation system) from WATEC. The price-performance ratio is very good, all delivery and installation deadlines were met on time. The cooperation with the chief planner Markus Gerster was excellent. Thank you for the good cooperation.

We have implemented several turbines (KDP) with WATEC and can emphasise the pragmatic as well as uncomplicated cooperation. The machines with PM generators run very smoothly. Rework, which was necessary due to previous suppliers, is carried out professionally and in coordination in the best possible way. Our experience is that Watec is highly interested in installing functioning and extremely good machines for the customer.

Due to the turbine design and the precise technical execution, I decided in favour of a WATEC turbine. The delivery and installation deadlines were met on time and executed professionally. The turbine performance is convincing and exceeded expectations after commissioning.

Made in Germany

For our Kaplan turbines, we rely on the cleanest workmanship and the highest quality "Made in Germany".
All the necessary components of our Kaplan turbine are manufactured in Germany. This enables us to guarantee long and trouble-free operation.
