New ERF350 Filters up to 3800kg of Contaminated Polymer Feedstock Per Hour With its newly developed ERF350, Ettlinger Kunststoffmaschinen GmbH, manufacturer of high performance melt filters and injection molding machines for high shot weights, sets new benchmarks in the filtration of contaminated polymer feedstock. This first model in a new, performance enhanced generation of the ERF series is suitable for processing all standard polyolefins and polystyrenes as well as numerous engineering plastics, for instance styrene copolymers, TPE and TPU. Like all ERF models, it is capable of removing foreign particles such as paper, aluminum, wood, elastomers or high-melting polymer composites containing up to 18% contaminants. And just like all other Ettlinger filter systems in the future, this brand new machine can be very easily integrated into Industry 4.0 environments. Depending on the type and level of contamination in the melt to be cleaned and the selected screen size, the ERF350 achieves a maximum throughput of 3800 kg/h in combination with the same ultra- low melt losses. It is thus positioned much higher up in the portfolio than the existing ERF250, which already impresses with a maximum throughput of 3000 kg/h. This represents an increase of around 4 TUBE NEWS December 2017 28% for the same filtration surface and typical small footprint. This value has since been confirmed during the first few months of practical duty with pilot customers. Users profit from more productivity when recycling contaminated waste plastics from industrial or consumer sources. Furthermore, experience to date has shown that energy consumption is about as low as that of the ERF250 in spite of the far better efficiency. Volker Neuber, Ettlinger’s managing director: “Users of our new ERF350 melt filter very soon realize that their investment pays for itself in minimal time owing to the clearly superior performance. It’s a highly efficient way for recycling plants to strengthen their competitiveness in terms of costs and performance in what is a fiercely contested market constrained by price tags. Companies which process large quantities will particularly profit from the new technology. Compounders where PP is converted for use in the automotive sector or manufacturers of, say, LPDE packaging films, are only two examples here.”
