BKG® HiCon™ K-SWE/RS Continuous Backflush Piston Screen Changer
Continuous backflush melt filters from Nordson handle highly contaminated polymers increasing product quality significantly by ensuring a constant process pressure with no line shutdowns. The BKG® HiCon™ K-SWE/RS is the perfect fit for various recycling applications.
Overview
The BKG® HiCon™ K-SWE/RS is a safe, reliable, mature system with a wide application window. It can easily handle most recycling materials, filtering out heavy contaminants. Additionally, the backflush feature enables for reuse of the filtration media, thus making it a reliable partner for increasing sustainability.
Keeping pressure constant is crucial for creating high-quality end products. Among our self-cleaning backflush systems, the BKG HiCon K-SWE/RS is the melt filter to pick when the available pressure after the extruder is high and slight additional pressure loss during screen change, and backflushing does not cause disruptions.
Automated venting
The BKG® HiCon™ K-SWE/RS can be equipped with an automated melt pressure-controlled venting start feature. This provides reliable, repeatable, and independent of material, throughput, temperature, system pressure, and viscosity changes venting procedure, ensuring a high-quality end-product.
