The double rotating hydropower screw
Fish ladder + fish descent + electricity generation
The patented, gap-free hydropower screw including the fish lift makes injury-free fish migration possible as well as the movement of microorganisms and sediment past transverse structures with simultaneous electricity generation.
How high is the efficiency of the Hydroconnect hydropower screw with double rotating cylinders?
The mechanical efficiency is up to 90%. This results in electrical efficiency, minus all the mechanical losses, of 65% even for small systems. In larger systems, the electrical efficiency increases to 70% and more.
With what water supply does the system work for electricity generation and fish migration?
The system can be used starting with a supply of 100 l/s. The highest flow rate is currently offered at 6,500 l/s. These systems are very well suited as residual water machines or as main machines for small locations.
What is the service life of a hydrodynamic screw with double rotating cylinders?
The HYDROCONNECT hydropower screw with double rotating cylinders is calculated for fatigue strength. The selected corrosion allowance with the choice and thickness of material ensures a minimum service life of 30 years.
Has 100% freedom from injury been proven by recognised centres for all river life?
Yes, of course. All research programmes and monitoring studies were accompanied by the Institute for Hydrobiology and Water Management (HG) at the University of Natural Resources in Vienna (BOKU). 100% freedom from injury was confirmed by BOKU in numerous studies.
