Francis Turbines

The Francis turbines are suitable for a drop from 10 to 100 m with variable flow rates from 1 to 20 m³ / s.

The water reaches the impeller conveyed by a spiral shaped duct with variable section and still passing through a distributor with mobile blades.

The impeller is an element that transforms the hydraulic energy into mechanical energy and is made up of a set of 14-22 fixed blades.

The field of maximum yields refers to a production field with the variability of the reduced flow rates.
