Francis turbines


Characterized by their shell-shaped inlet conduit and a very particular runner, these turbines well fit heads from 20 to 200 meters and performing very high design point efficiencies (up to 94%). Each turbine should be calculated accordingly to the site characteristics (head and maximum flow), looking for the optimal combination of rotation speed and overall […]

Kaplan turbines


These vertical axis units well fit with low head, from 2 to 30 meters, and relatively high flow situations, showing a very wide high efficiency field thanks to their double regulated mechanisms: accordingly to the available flow, the distributor and the runner blades (from 3 to 5) take a position following a collimation curve, allow […]
