We generate energy for small hydroelectric plants.

Solutions for low fall. Speed increasers for demanding applications.

Zanini Renk multipliers for low loss are designed with state-of-the-art tools to develop customized solutions, maximizing ruggedness, energy efficiency and complying with the available space at the plant.
The multipliers incorporate an axial bearing to withstand the turbine’s axial loads.
Zanini Renk offers two lines of speed multipliers: planetary and parallel ones.

Discover the advantages of the Zanini Renk multipliers

  • Smaller power room
  • Smaller equipment footprint (Generator, crane)
  • Increased generator speed, which increases its yield
  • Possibility to eliminate the thrust bearing
  • Low maintenance (bearings sized for 100,000 hours)
  • Low noise
