Speed Control
Regulators for Kaplan, Francis and Pelton turbines
Speed control
Our speed regulator offers a universal regulation solution, designed to adapt to all types of hydraulic turbines: Kaplan, Francis and Pelton. Its versatility makes it the ideal choice for both new installations and the modernization of existing systems, whether mechanical or electronic.
High-performance and flexible, it provides primary regulation for isolated grid sites and can also handle secondary regulation for interconnected installations.
Hydraulic power units
For a turnkey solution, we expand our expertise in collaboration with our partner: we design and manufacture, partially or completely, the hydraulic servo units that control your turbine.
Custom design according to your needs
Sizing adapted to the turbine
Quality hydraulic components
Complete FAT testing in factory
