Austrian plastics recycling system manufacturer, EREMA, has launched a new business unit, POWERFIL, to offers both the SW RTF partial surface backflush filter system and the Laserfilter as individual components.
The company said that technical modifications were made to the filter systems prior to the foundation of the business unit and potential users can upgrade their existing extrusion equipment from alternative suppliers by adding an of the EREMA melt filters.
“With the new POWERFIL portfolio we aim to show even more clearly that our filter systems represent a high-performance solution also for third-party extrusion systems – although the technology used is not new, but has already been tried and tested thousands of times,” commented says Manfred Hackl, CEO EREMA Group. “EREMA filters are in use on over 5000 plastics recycling systems around the world.”
EREMA said that with its Laserfilter, a continuous filter system with a screen size of 70µm is n operation for the first time. A gentler filtration process has been made possible by rheological optimisation of the support breaker plate, enabling a reduction of flow resistance.
The company added that enquiries for the Laserfilter, which is already established in the post-consumer field, are increasing from customers in the PET sector. The reason for this is that the increased use of rPET in end products requires high process stability despite higher degrees of contamination at times.
The Laserfilter is said to be able to process input material with a degree of contamination of over 1% without any difficulty. The functional principle avoids dead spaces and makes for short dwell times which in turn prevents "black spots" with PET.
Thanks to the newly developed discharge unit, melt losses are said to be reduced from the normal 1% to 2% with piston filters down to a tenth.
"In recent years the growing recycling market and the noticeable parallel increase in more heavily contaminated input materials have led to a growth in the demand for efficient filtration systems – also in the case of existing extruders,” he said.
Visitors at the Fakuma trade fair will be able to see them from 17 to 21 October on the EREMA stand, Hall A6 Stand no. 6314.
