Francis turbines works from about 10 meter to 200 meter water head and is very popular due tyo good performance and controls. We deliver systems form 20 KW up to MW sizes for different water heads.

The complex mechanics with adjustable vanes make regulation very good . Efficiency can be 90% in a good design
