The VICO-Screen® is made by winding a continuous V-sectioned extruded wire helicoidally onto support rods. At each intersection, the V-sectioned wire is welded to the support rod by an electric resistance welding process. The VICO-Screen® has extremely precise continuous openings thanks to which a large open area is obtained. This, in turn, guarantees an extremely low pressure drop through the filtering surface. Thanks to this feature, the VICO-Screen® is ideal as a support or container for catalysts or resins and as a filter for sand or particles, even of extremely small dimensions. The high number of welds also gives the screen an extremely high mechanical resistance and a very long lifespan. The continuous openings and triangular section of the wires ensure that there are only two particle contact points, thereby minimising the risk of clogging. Additionally, thanks to the particularly smooth surface of the VICO-Screen® the abrasive effect due to contact between the product and the filtering surface is greatly reduced.
