Reduce Polymer Residence Times with this Large-area Filter

With a screening area of 30 m², this firm offers the largest Screen Changer for filtration of polymer melt. A combination of the proven bolt-type screen changer with "micronex" filter-candle elements is the basis for this innovation. A single person can exchange used filter candles within minutes. Contrary to existing large-area filtration, where throughput time of the polymer melt is several minutes, this new design enables material residence times of a few seconds. PET processes without the solid-state post condensation for producing PET granules in bottle grade viscosity can profit from this new design, says the manufacturer. — Maag Pump Systems Textron AG, Oberglatt, Switzerland
