What are the benefits of using Archimedes Screws over other technologies?

[fancy_list style=”arrow_list”]

  • very cost effective relative to other turbines and waterwheels
  • better efficiency at less than optimum flows compared to other turbines and water wheels.
  • relatively simple to install, use and maintain
  • slow rpm’s and therefore longer lasting bearings
  • robust highly reliable design using standard 3 phase generators and other components easily available
  • ability to handle debris without need for fine screening because there are no small nozzles
  • fish friendly, can safely pass fish downstream
  • can be used on heads as low as 1 meter and flow as low as 100 liters per second
