Abstract:
A plant (10) for treating air with forced- ventilation heat exchangers, wherein an airflow strikes the heat exchangers for carrying out the exchange provides a conveyor (40) of the airflow, a fan (41) arranged for receiving the airflow coming from the conveyor (40), an electric generator (42) connected to the fan (41), an electric regenerating inverter (43) connected to a supplying network (V) of the plant; the fan (41) is moved by the airflow corning from the conveyor (40) and drives the electric generator (42) that generates electric energy returned to the supplying network (V) through the inverter (43); in this manner the electric consumption of the plant is reduced.
Abstract:
A plant for processing laminated material or in general sheet material from a coil provides for a supply station (10) for moving, supporting, and rotating braked unwinding a coil (A) of said material, a processing station (30) for processing the unwound material (L) coming from the supply station (10), a storage station (50) for rewinding braked in coil (B) the processed material (L); in order to recover electric energy, the use of electric generators (12; 42) for the braking action is provided for.
