hydro power

The Pentair Fairbanks Nijhuis Bi-directional Turbine was specifically developed and optimized to generate energy from ultra-low head tidal streams. The design features a speed controlled direct drive, a permanent magnet generator and a fully reversible impeller to maintain optimal performance in both flow directions during a complete tidal cycle. The design is patented and proven fish friendly, which allows fish to pass the turbine unscathed and improves fish migration.

  • Proven fish friendly for eel and scaled fish
  • High and proven efficiency in complete tidal cycle
  • Variable speed operation to maintain maximum efficiency during a complete tidal cycle
  • Efficiency is equal in both flow directions (reversal of blades during reversal of tide)
  • The turbine can be operated as pump
