Siphon turbines cover the range of very low heads (from 1 to 3.5 meters).
The concept developed by Mhylab aims to equip existing dams on high-discharge rivers. The turbines are primed by creating a vacuum in the upper part of the conduit. To stop the turbine it is sufficient to open a flap that allows air to enter the machine. This simple and efficient system avoids the expenditure of a valve.
