TH 04.2 – Autonomous Electric Brake Francis Turbine

The TH 04.2 model is an advanced, scaled-down Francis turbine (or reaction turbine) simulator, specifically designed to facilitate detailed study and real-time visualization of the behavior and dynamic properties of such turbines.


It features a transparent casing, an innovation that allows for direct observation of how water flow drives the rotor. This visibility extends to the movement of the distributor’s guide vanes, crucial for precise regulation of incoming water flow, providing a unique and comprehensive educational experience.

It includes an adjustable valve for controlling the water inlet flow, offering the flexibility to operate with different water volumes according to experimental requirements.

Its braking system, powered electrically, allows for adjustments in revolutions per minute, enabling experiments with various workloads.

The equipment is distinguished by its full computerization. This means critical variables such as inlet pressure, flow rate, braking torque, and others are monitored and displayed in real-time through a computer integrated into the device, facilitating precise and efficient data interpretation.

Thanks to its comprehensive design, which includes a water tank, pump, and all necessary instruments mounted on a mobile laboratory cart, the TH 04.2 turbine allows for entirely autonomous operation, optimizing practical learning in educational environments.
