Hydropower from the Alps.
The family business AC-TEC is specialized in the production of small hydro power plants for many decades and manufactures customized water turbines and the corresponding electrical part. We combine experience and innovation. Our business is located in Caldaro, a village in South Tyrol.
The family business from Südtirol
Amidst the breathtaking backdrop of the Alps, in Kaltern, our family business has deep roots. As a family business, not only the quality of our products is of the utmost importance to us, but also the personal relationship with our customers and employees.

At AC-TEC, we pride ourselves on embodying the values and spirit of a family business while meeting the challenges of the modern world with innovative solutions.
Contact nowOur Turbines
The Company, thanks to an excellent team, which is constantly experimenting with new technological solutions, has already produced over 600 turbines. The company puts a lot of attention in selecting the best components, materials and suppliers in order to offer a high quality product.
Francis Turbine
It is suitable for medium heads and medium quantities of water. The appropriate difference in height for this type of turbine is in the range of 20m to 200m. The output is between 50kW and 3MW.

Pelton Turbine
The Pelton turbine is an impulse turbine and works with large heads and relatively small amounts of water. The advantage lies in the relatively constant efficiency even with changing water levels.
