2 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 of Francis turbine Vertical Francis units Horizontal Francis units Vertical or Horizontal Francis units with Pressure Regulating (or Ramping) Valves Double Francis units Twin and Camel-back horizontal Francis unitsApplication range Heads from 10 m up to 750 m Wide range of discharges Operating at part load and deep part load Outputs up to 350 MWAdvantagesPerformanceFrancis Turbines reach highest efficiencies and highest power output of all water Turbines .

3 Each turbine is hydraulically optimized using CFD calculation and model tested in our hydraulic laboratory in order to provide optimal solution and maximum performance and value for design process of Francis Turbines is focused on robustness and reliable operation. As a result, our Francis Turbines can operate reliably and safely over several decades with minimum Power latest hydraulic and mechanical developments on Francis turbine runners enable our Turbines to continuously and safely operate over wide operating ranges, covering part load, deep part load and in special cases even operating from 0-100% power solutionsFrancis Turbines can be designed in vertical or horizontal configuration.

4 Horizontal Francis unit arrangements are limited by its capacity and size for which Litostroj Power can provide single or double runner configuration. Advantage of horizontal double Francis units is compact design, providing smaller units in size and being competitive in price. For large units vertical arrangement is reduce drat tube vortex effect on stable operation of the turbine and allow a wide range of operation air admission under the turbine runner either through the unit shaft or through the special piping provisions is supplied. For special applications regulation of air admission can be case of penstock safety (pressure rise) or ramping requirements, pressure relieve valves (PRV) or Energy Dissipation Valves are installed.

5 PRV is hydraulically or electrically connected to the turbine regulation system and acts as penstock protection system which synchronously redirects the water discharge from the turbine to the PRV during fast distributor featuresLitostroj Power produces all the turbine runners in-house to ensure best quality of the turbine most important part. For low-head turbine runners we usually use welding technology where crown and band are welded together with runner blades. Blades are cut-out from steel plates, hydraulically pressed with template to appropriate shape and CNC machined to its final hydraulic middle and high-head Francis runners CNC machining of the integrally forged part is an option.

6 For large high-head Francis units, Litostroj Power possess the technology to manufacture the runners from the two CNC machined parts that are later welded in the middle of the runner blade where lowest stresses in material are references from 2010 Project nameYearProject typeShaft [m]Pt [kW]D [mm]No. of UnitsLe e, Croatia2010 New projectVertical39,572203829332 Wawaitin, Canada2010 New projectVertical36,49776018002 Moste IV, Slovenia2010 RefurbishmentVertical157,6285408501 Bone Creek, Canada2010 New projectHorizontal148,3895747002 Sheldrake, Canada2012 New projectHorizontal63,771237211602 Toro 3, Costa Rica2013 New projectVertical2452402011262 Lower Baker, USA2013 New projectVertical73,672309521501 Val Jalbert, Canada2013 New projectHorizontal99,031799611101 Doblar 1, Slovenia2014 RefurbishmentVertical41,9951821273 Rama, U1, Bosnia and Herzegovina2015 RefurbishmentVertical2858178827501 Rama, U2, Bosnia and Herzegovina2015 RefurbishmentVertical293,619570019601 Dubrovnik.
