A reliable and efficient solution in the green energy production Francis • Reliable and eco--friendly • Heads from 10 m up to 750 m Turbines • Wide operating range of heads and discharges • Flexible operation at part load and deep part load • Outputs up to 350 MW • Runner diameters up to 7,000 mm • Solution tailored to customer needs • High efficiency level www.litostrojpower.com Most common type of water turbine in use today, characterized by high efficiency levels, reliable operation and robust design.

Litostroj Power Francis turbines are designed in simple and rigid manner to enable ease of maintenance of all main unit parts. Francis unit is considered as most simple and robust machine that can be used for transformation of water potential energy to mechanical power via fixed runner blades and further to electrical grid. Our turbines excel in reaching high efficiency levels.

Advantages To reduce drat tube vortex effect on stable operation of the turbine and allow a wide Performance range of operation air admission under the Francis turbines reach highest efficiencies turbine runner either through the unit shaft and highest power output of all water turbines. or through the special piping provisions is Each turbine is hydraulically optimized using supplied. For special applications regulation of CFD calculation and model tested in our air admission can be provided. hydraulic laboratory in order to provide optimal In case of penstock safety (pressure rise) solution and maximum performance and or ramping requirements, pressure relieve value for customer. valves (PRV) or Energy Dissipation Valves are installed. PRV is hydraulically or electrically Reliability connected to the turbine regulation system Mechanical design process of Francis and acts as penstock protection system which turbines is focused on robustness and reliable synchronously redirects the water discharge Lešće HPP; Croatia, 2 x 22 MW, Vertical Francis turbine operation. As a result, our Francis turbines from the turbine to the PRV during fast can operate reliably and safely over several distributor maneuvers. Types of Francis turbine decades with minimum maintenance. • Vertical Francis units • Horizontal Francis units Manufacturing features Flexibility Litostroj Power produces all the turbine • Vertical or Horizontal Francis units with Litostroj Power latest hydraulic and mechanical runners in-house to ensure best quality of Pressure Regulating (or Ramping) Valves developments on Francis turbine runners the turbine most important part.
