Here you'll find our historic projects, testimony to Rutten Electromecanique's expertise.
Omega S
As early as 1987, Rutten Electromécanique S.A. developed a hydroelectric turbine concept adapted to low heads, those between 1.80 m and 4 m.
The Omega Siphon turbine was designed for existing fixed dams (rock dams, needles, etc.).
The absence of civil engineering was the first goal developed by the company.
Rutten S.A., with the help of the Turbomachinery Department of the University of Liège, optimized the blade profiles.
