Speed Control

Regulators for Kaplan, Francis and Pelton turbines

Speed control

Our speed governor offers a universal control solution designed to suit 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-performing and flexible, it handles primary regulation for isolated grid sites and can also manage secondary regulation for interconnected grid. Based on PLC technology, our governor ensures easy maintenance and long-term availability of spare parts. Its design strictly complies with international standards IEC-61362, IEC-60308, IEEE 125-2007, and IEEE 1207-2011.

Hydraulic power units

In close collaboration with our partner, we also handle the custom design and manufacture of hydraulic power units for actuating the turbine control components.
