Renewable Energy / PAE Hydrodynamic Screws    Extras Application Photographs Low investment costs + low maintenance costs + high profit = high cost-effectiveness & short amortization Description RONCUZZI® PAE-type Hydrodynamic Screws are designed for the production of electric energy. The machine works thanks to the difference of energy potential between two different points in a water flow. The water, thanks to the difference between two levels of natural flow, is used by a rotor (that generates energy) and then flows again into its channel. The limit of this equipment is reached with geodetic heights of more than 10 metres and flow rates higher than 5,500 l/s. Function PAE-type Hydrodynamic Screws can be used in many applications: Replacement of small turbines which require reconditioning; Replacement of damaged water-wheels; Clean water discharge in waste water treatment plants; Surplus water utilization in existing channels or weirs; Utilization of water power in long-term unused channels; Utilization of cooling water from electric power plants; Utilization of processing waste water (from paper mills, mills etc.). Performance & Technical Features - Benefits No control system required. The screw automatically adapts to mains frequency and to the water flow rate. PLC and frequency converter are not required. Higher efficiency than water wheels or small turbines Constant and stable efficiency Solid sturdy design No cleaning, little maintenance, shortest possible machine downtime No fine screen needed Little underground digging required compared to turbines Fish-friendly Technical Catalogue Technical Catalogue currently not available Brochure PAE Hydrodynamic Screws Brochure No. 063001983 Last Edition: 05/11 PAE_EN_0511.pdf   Print
