ECO Maag’s Ettlinger brand includes the ECO line of high-performance continuous melt filters for post-consumer and post-industrial PET recycling. The filters efficiently remove foreign particles such as gels, black specks, paper, wood, aluminum, copper, rubber, silicone and polymer composites. Typical applications for the filters are extrusion systems in which PET bottle flake is converted into food packaging films, tape and fibers, or in compounding and repelletizing processes. They are appropriate for contamination levels up to 1.5 percent.
What’s new? The ECO 350, which replaces the company’s ECO 250 model, and the ECO 500, which replaces the ECO 250 Twin. New features include a system that makes the contamination discharge more concentrated, reducing the loss of PET melt. Additionally, the new melt filters provide easier access to the scraper system for maintenance. The ECO 350 has a maximum throughput of 5,512 pounds per hour and a total filtration surface of 1.7 square feet. The ECO 500 can achieve throughputs of up to 8,800 pounds per hour and has a total filtration surface of 3.4 square feet. The two new models join the ECO 200, which has a throughput of 2,646 pounds per hour and a total filtration surface of 1.35 square feet.
Benefits Higher throughputs, effective filtration and operator convenience. The filters provide continuous operation with a constant pressure on the outlet side, resulting in extremely low melt losses and consistent melt flow without dead zones or degraded polymer quality. Additionally, users can go weeks or even months without replacing the screens.
