Hydrodynamic Screw

ALWAYS THE BEST POWER PLANT SOLUTION.

Hydroalp provides hydrodynamic screws for low head plants from a few meters to tens of meters and with flow rates from a few cubic meters up to a few tens of cubic meters per second.

Screws (or Archimedean screws) are the ideal solution for all those power plants, where the use of Kaplan models would be uneconomic due to the combination of low power and low output. Depending on the flow rate fluctuations, screws can operate at fixed or variable speed.

Variable speed turbines allow to modulate the turbine input flow rate while keeping the up stream level constant and thus maintaining optimal operating conditions.
