Continuous Melt Filter for Recycling
Nordson’s continuous backflush melt filters are designed to handle highly contaminated polymers, significantly enhancing product quality. By maintaining a constant process pressure and eliminating the need for line shutdowns, the BKG HiCon K-SWE-4K/RS is the ideal solution for various recycling applications.
Overview
The BKG HiCon K-SWE-4K/RS is a reliable recycling melt filter that provides exceptional performance across a wide range of applications. Capable of managing most recycling materials, it effectively filters out heavy contaminants while its backflush feature allows for the reuse of filtration media, promoting sustainability and reducing operational costs.
Maintaining consistent pressure is essential for producing high-quality end products. Among Nordson’s self-cleaning backflush systems, the BKG HiCon K-SWE-4K/RS is the optimal choice for applications where medium inlet pressure and potential disruptions from screen changes and backflushing require precise and stable pressure control.
Automated Venting
The BKG HiCon K-SWE-4K/RS can be equipped with an automated melt pressure-controlled venting start feature. This ensures a repeatable and reliable venting process, independent of material, throughput, temperature, system pressure, or viscosity. The result is a consistently high-quality end product.
