About Francis Turbine Trainer
FRANCIS TURBINE TRAINER
- The unit enables examinations of the function and operating behavior of a Francis turbine.
- The dimensions of the trainer guarantee realistic measured values.
- The closed water circuit consists of a tank with optional cooling, a centrifugal pump and a flow control valve for adjusting the inlet pressure.
- The transparent operating area of the turbine enables an optimal view of water flow, rotor and guide vanes during operation.
- By adjusting the guide vanes the angle of attack, the cross-section and thus the output of the turbine are changed.
- An asynchronous machine is used as a generator for loading the turbine.
- A pump with variable speed via frequency converter provides for an energy efficient operation.
- The measured values are displayed digitally and processed further on a PC.
- The output data of the examined turbine are determined and represented by characteristic curves.

Transparent Operating Area for Enhanced LearningThe unique transparent enclosure design of the Francis Turbine Trainer enables students and faculty to observe the water flow directly within the turbine assembly. This optimal visibility is invaluable for understanding dynamic flow behavior, enhancing the educational experience through real-time observation and improved conceptual clarity.
Reliable and Accurate MeasurementsThe trainer is equipped with a rotameter and digital sensors for flow, along with both bourdon gauge and electronic transducer for pressure readings. These tools deliver exceptional accuracy (1%) within a range of 050 LPM for flow and 01 bar for pressure, ensuring dependable data for experimentation and analysis.
Flexibility and Safety in OperationSafety and operational ease are prioritized through features like overload protection, a fully integrated control panel with status indicators, and a sturdy, mobile powder-coated frame. The closed-loop water system with an inbuilt sump tank enables extended experiments without water loss or external plumbing.
