The potential

Water is the origin of life on planet Earth.
In nature Water is responsible for the creation of ecosystems.
Thanks to Water mankind was able to make one of the most important discoveries: to transform its potential and kinetic energy into a mechanical one.
This is the result achieved by turbines. Their birth goes back to the Second Industrial Revolution, at the end of the nineteenth century and nowadays its efficiency equals over 80%.
Hydroelectric power is one of those renewable resources that regenerate at the least same speed with which they are consumed. Italy produces more than half of these.

The energy

Hydraulic turbines take advantage of the available fall, which is the height where the tank is located upstream, compared to the one downstream. The water flow is channeled under pressure through a nozzle. The effect is a high power water flow that hits the blades fixed onto a wheel allowing it to spin.
There are two different types of turbines: action and reaction ones. In the action-type turbines the transformation happens in the water distributor, these types of turbines are selected whenever head is greater (up to 1.000 meters) and flow rate is mediocre. Whenever head is inferior (up to 200 meters) reaction turbines are used instead, in advantage to a major water rate thanks to the exploitation of the runner.

The main hydraulic turbines employed nowadays are:

  • Kaplan, high flow rate and low head applications.
  • Bulbo, developed to reduce civil works and the enviromental effects.
  • Francis, direct installation of the runner on the generator shaft.
  • Pelton, high efficiency even with considerable flow rate variations.

Hydroelectric energy is the future. We provide you the instruments to achieve it.
