Reliable Backflush Recycling Filter for Contaminated Polymers
Nordson’s continuous backflush melt filters are engineered to handle highly contaminated polymers, significantly improving product quality. By maintaining constant process pressure and eliminating line shutdowns, the BKG HiCon K-SWE/RS is an ideal choice for various recycling applications.
Overview
The BKG HiCon K-SWE/RS is a dependable and mature Backflush Recycling system, offering a broad application window.. It effectively manages most recycling materials by filtering out heavy contaminants. Its backflush feature allows for the reuse of filtration media, supporting sustainability and reducing operational costs.
Maintaining consistent pressure is essential for producing high-quality end products. The BKG HiCon K-SWE/RS is specifically designed for scenarios where high pressure is available after the extruder, and minor additional pressure loss during screen changes or backflushing does not disrupt operations.
Automated Venting
The BKG HiCon K-SWE/RS can be equipped with an automated melt pressure-controlled venting start feature. This ensures a repeatable and reliable venting process, unaffected by changes in material type, throughput, temperature, system pressure, or viscosity, resulting in consistently high-quality melts.
