Continuous screen changer SFneos

rotary disc type

The Rotary Technology has been used successfully in PVC processing and PVC recycling applications for more than 30 years. The SFpvc Filtration Systems have been specially designed for thermally unstable and chemically aggressive processes such as those occurring in PVC recycling. The rheologically optimized filtration systems with their dead-zone free melt channel design and short flow path allow gentle processing. The advantages of the SFneos Filtration System Constant By always keeping the size of the free active screen area constant, the pressure can be kept constant during the whole production process (max. pressure variations of ±1,5bar). Also, melt temperature and viscosity are permanently free from variations. Thus, the end product quality is always constant. Quality Melt purity and quality downstream of the filtration system are permanently achieved. The flow channels are rheologically optimized. Streamlined Due to the optimal rheological flow channel design, the dwell time of all the melt in the filtration system is very short (< 1 minute). No danger of material burning in dead spots. Straightforward The operator is informed in time about upcoming screen changes by the control system. Changing screens is a simple and quick procedure and does not influence the process and product quality. Compact size The compact design of the SFneos Rotary Filtration System enables simple and cost-efficient integration even in a very confined space. Due to the compact design and the high quality insulation, the energy consumption is extremely low.
