Continuous filtration system

High Performance Melt Filter ECO

High Performance Melt Filter ECO

The continuous melt filters of the ECO series are mainly employed in PET and PA applications due to their special design and for filtering polymer feedstock from industrial waste with a low level of contamination or lightly contaminated post-consumer waste, as well as for clean virgin material. Our ECO melt filters are capable of processing a wide range of polymers. All solid or elastomer foreign particles such as gels, black specs, paper, wood, aluminum, copper, rubber, silicone or high-melting polymer composites are efficiently removed. In particular, there is significantly less degraded PET in the form of black specks. For this reason, the classic application for ECO melt filters is extrusion systems, for instance where recycled PET bottle flake is converted into food packaging films, packaging tape, and fibers. PET repelletizing and compounding processes in general are other potential areas of use. ECO melt filters can in principle be used in any extrusion line – either single or twin-screw and irrespective of the type of pelletizing system or other downstream unit. Three different sizes – ECO 200, ECO 250, and ECO 250 Twin – enable throughputs from 150 to 6,000 kg/hour depending on the application.
