Efficient Backflush Filter for Recycling
Nordson’s continuous backflush melt filters effectively handle highly contaminated polymers, significantly improving product quality. By ensuring constant process pressure and eliminating line shutdowns, the BKG HiCon K-SWE-4K-75/RS is an ideal solution for various recycling applications.
Overview
The BKG HiCon K-SWE-4K-75/RS is a robust, reliable system designed for a wide range of recycling materials. It efficiently filters out heavy contaminants, while the backflush feature allows for the reuse of filtration media, contributing to sustainability and cost savings.
Maintaining consistent pressure is critical for producing high-quality end products. This melt filter is particularly well-suited for situations where the available pressure after the extruder is low, and additional pressure loss during screen changes and backflushing could cause disruptions. With 75% of the filtration area always available, the system minimizes differential pressure and ensures stable operation.
The BKG HiCon K-SWE-4K-75/RS excels in processing highly contaminated polymers with low available operating pressure, making it a reliable choice for challenging applications.
Automated Venting
The BKG HiCon K-SWE-4K-75/RS can be equipped with an automated melt pressure-controlled venting start feature. This ensures a repeatable and reliable venting process, regardless of material, throughput, temperature, system pressure, or viscosity, delivering a consistently high-quality melt.
