EREMA Double Disc Technology DD

Many Erema-type plastic recycling applications suffer under problematic feeding influences such as high residual moisture and large density variations in the feed material, as well as too large feeding portions, which typically have a negative influence on the subsequent extrusion process. The extruder has to deal with these “adverses” and shows this in common with reduced or varying output performance, possibly inconsistent melting performance (moisture!), reduced product quality and increased wear, besides reduced overall productivity.

EREMA Filter Systems for Thermoplastics

As the worldwide leader in manufacturing of plastics recycling equipment Erema has a wealth of experience in filtering polymer melts. Over the years polymer filtration has become one of Erema's key areas of expertise, due to its quality-defining aspects. There are currently more than 2000 Erema polymer filters being used all over the world for numerous different applications to the satisfaction of Erema's customers. As your reliable partner for filtration solutions we offer a wide production program of advanced filter systems, comprehensive advice, prompt service and worldwide support. The Technical Centre at our headquarters in Linz/Austria gives you the opportunity to conduct filtration tests under realistic production conditions. Different melt filter systems for almost any specific requirement Criteria such as throughput capacity range and type of application, besides individual process requirements, are critical factors in choosing the most cost-efficient melt filter solution. Our wide range of filters and the various sizes available mean that you will nearly always find a custom Erema filter system to meet your specific needs. Erema melt filters meet the very highest quality standards and are characterised by their heavy-duty construction, high degree of automation and high-performance availability. Our products range from simple, manual lever-operated pivot disc safety filters to one-, two- or four-piston partial area backflush screen changers as well as the high end laser filter for heavily-contaminated polymers.

Laser Filter: The Filter with the extreme separating capacity

The name ”Laser Filter“ originates from the fact that the core elements of this filtering system, the filter screens, are drilled (shot through) using laser technology, with the holes designed conically, making them self-cleaning. (see picture below) Used plastic waste contains a large proportion of unwanted material and contamination. Despite complex washing and separating processes, the removal of residual contamination through the melt filtration system in the subsequent extrusion process causes huge problems, particularly in terms of economic efficiency. Conventional melt filtering technology on the market fails to meet the demands in many cases. This is all the more so if the used plastic waste is to be used to manufacture pellets (recyclate) in film quality. In order to perform these tasks, Erema has developed a continuous high-capacity filtering system: the EREMA LASER FILTER. A quantuum leap in filtering capacity When traditional cartridge filters with wire mesh screens are used, heavy contamination of the screens rapidly results in excess pressure, switching off the extruder in seconds. Using the Laser filter, a continuous filtration and thus extrusion process can be maintained for days and even weeks. Comparisons made in the Erema’s technical centre and in many customer applications confirm the impressive capacity of the new filtering system, e.g. in filtering plastic melt from washed post-consumer plastic waste. The results: 3 –5 minutes screen change interval using traditional cartridge screen changers high personnel costs high risk of injury limited filtering capacity 2 hours screen change interval with modern state-of-the-art partial area backflush screen changers (e.g. Erema SW 8/170 RTF) reduced personnel costs reduced risk of injury increased filtering capacity 600 –1000 hours screen change interval with the EREMA LASER FILTER! extremely high filtering capacity practically no need for personnel minimum melt loss fully automatic constant pressure operation

The Erema VACUREMA technology for PET processing and PET recycling

This unique, well proven and extremely flexible technology can process PET materials and any blends of materials coming along in the form of virgin pellets, post consumer bottle flakes, preground preform flake, preground cut out frames from thermoforming, precut fibre waste, and others, without external upstream crystallisation and without upstream predrying, in various bulk densities, into melt filtrated, virgin-like pellets or directly into end products such as sheet, fibre or strapping. Different plant concepts can be configured depending on customers' individual requirements regarding required IV and required degree of decontamination.
