6 ANDRITZ Experts in hydropower

7 ANDRITZ Experts in hydropower Working Range of micro hydropower

8 ANDRITZ Atro Archimedean Screw Archimedes invented the screw pump 2300 years ago ANDRITZ Atro designs and builds screw pumps for decades

9 ANDRITZ Atro hydropower screw as a turbine ANDRITZ Atro invented the hydropower screw 15 years ago The genius principle is turned around The hydrodynamic screw is placed inclined in flood direction in the river The water flow makes the screw rotating. The energy is given to a generator via a gearbox

10 ANDRITZ Atro hydropower screw Do you want to invest into renewable energy? Do you have problems with the interconnected grid, because there is none? because the power lines are to weak?

11 ANDRITZ Atro hydropower screw Do you have nearby a natural river flow with currents? an owerflow over an existing dam? an irrigation channel? old unused hydropower site? a clean water outlet of sewage treatment plants?.

ANDRITZ Atro hydropower screw Perfect micro

=> Power output up to 500 kw at sites with concerns

12 ANDRITZ Atro hydropower screw Perfect micro hydropower utilisation at sites with small heads from 1 to 10 m at sites with flows from 0,25 to 10 cbm/sec. => Power output up to 500 kw at sites with concerns about fish mortality with high efficiency especially at partial load with small investments and maintanence costs

13 ANDRITZ Atro hydropower screw Main Components Scoar screen Shut down device Drive unit with gearbox and generator Control cabinet: AHC - ANDRITZ hydro screw controller Archmimedean Screw with upper and lower bearing incl. splash plates and different types of troughs

14 ANDRITZ Atro hydropower screw Advantages No danger of blockage due to big passages No need of expensive fine screening Very fish friendly Very low wear due to slow turning screw

15 ANDRITZ Atro hydropower screw Advantages Enviromental friendly, because of little effects in the surrounding world Minimal civil works No deep excavating Less regulations, smaller process of permission

16 ANDRITZ Atro hydropower screw At a glance High efficient turbine for small heads 1-10 m Flows from 0,25 10 cbm/sec. Sites with concerns about fish mortality Trouble free operation at low maintanence costs Small investments in machinery and civil works
