Environmentally Friendly Water Hydraulics<\/h1><\/div><\/div>\n\n
<\/span><\/div>\n<\/div>\n<\/div>\n\n
\n
\n
Environmentally friendly water hydraulics is one of the central research directions of the Laboratory for Fluid Power and Controls. We research the development of hydraulic systems, valves, actuators, and materials that use water instead of mineral oil as the working medium. In doing so, we contribute to the development of safer, more sustainable, and more environmentally friendly fluid power solutions.\u00a0<\/div>\n<\/div><\/div>\n\n
