Francis turbines

FRANCIS turbines are reaction turbines that are mainly used for medium head power plants with a wide range of flow rates.

The efficiency of these turbines at the optimum point is approximately 90%. They allow variations between 105% and 40% of the nominal flow and between 120% and 60% of the nominal net head.

SERVO SHIP builds this type of turbines for power ratings up to 3,000 KW, with jumps between 15 and 200 meters. Both horizontal and vertical axis.

Additionally, and in order to take advantage of existing civil works infrastructures, these turbines are built in open chamber for head between 3 and 7 meters.
