Amphibious Turbine

The Amphibious Turbine is an electric power generation technology through hydraulic potentials available in dams, pipelines, spillways, waterfalls and other sources of accumulated water energy. The Amphibious Turbine is a fully integrated equipment including electric generator and turbine. The electric generator is the wet submersed type, being cooled by the own fluid that goes alongside the motor and guarantees excellent thermal exchange and high performance condition. The turbine is designed according to the application operating conditions using the CFD software for geometry optimization and high performance reach.

* CFD (Computional Fluid Dynamics) is a computational simulation software used worldwide, for example, by the aeronautics and automotive industry.

Distributed Generation

Distributed generation might be defined as any production of electric energy from concessionaires or authorized agents directly connected to the electric distribution system and / or located in the consumer.

It is an expression used to designate the electric generation carried out next or close to the consumer, independently of the power, technology and energy source.

The advantages of distributed generation, when compared to central generation, are saving on large investments in installation and transmission, reducing losses in this process and improving the stability of the electric power service.

Turbine's Optimization

Each turbine is unique. Technologies used by HIGRA for design and optimization are based on each facility‘s features. It guarantees the application´s maximum hydropower use. For that HIGRA uses CFD state-of-the-art simulation software to generate turbine geometries.

Ways of Installation

Reservoirs and Dams

Application in reservoirs and dams with hydraulic potential, where a water discharge/outlet makes possible to take advantage of this energy.


Application in rivers, reservoirs or dams where a closed conduit makes possible to take advantage of the existing geometric difference for the generation of energy, using a dimensioned and allowed flow.

Replacement of Pressure Reducing Valves

PRV (Pressure Reducing Valve) replacement in water supply systems, controlling the required pressure at the outlet and taking advantage of the energy, previously dissipated by the valves, for the generation of electric energy.

Integrated Solution

The amphibious turbines are supplied with the complete systems of driving, monitoring and return of synchronized electric energy to the local energy feeding networking.

For that, HIGRA engineering has developed, associated with major global brands, all the automated control of energy and rotation of the electric generator, always seeking the best operating point.
