Opening Size range: Archimedean Hydropower Screw uses the Archimedean principle to convert the potential energy of water on an upstream level into the electrical power. It is an open channel system where the water flowing down from upstream rotates the screw at around 15 – 30 RPM. The RPM is stepped up through a 3-stage helical gearbox to meet the generator speed. It can generate electricity from 15% of its designed flow to 110% of overload capacity.
Series: Type SH, Type BS, Type BT & Type CS
Discharge Capacity('Q' m3/s): 0.1 m3/s to 11 m3/s
Screws can be installed in parallel to accommodate higher flow
Range of Hydraulic Head('H" in Meters): 1 m to 10 m
Electric Power Output(in Kw): 9.81 x Q x H x Ƞ (overall efficiency)
Hydropower Screw Efficiency Range: 80 – 90%
Power Generation Range per Screw(in meters): 5 kW – 500 kW
Screws can be installed in parallel to meet Higher Generation
Screw Diameter Range (in meters): 0.4 m – 4.50 m
Typical Installation: STPs/ WTPs Outfalls
Run of River sites
Falls at Canals
At water outlets of Thermal power plants locations
At the tailrace of small/mini Hydropower plants
Due to its compact installation, the screw can be installed at any location with desired head & flow and fairly enough space
