EREMA - Model SW RTF -Melt Filter System
Without efficient filtering it is not possible to obtain high quality recyclate. This applies to all application cases in plastics recycling. That is why from the very beginning, EREMA has made this quality-decisive aspect a core element of its systems. Perfectly implemented in innovations and partially patented filtration systems. Features they all share are process consistency and maximum filtration capacity.
Robustness, high level of automation and highest possible availability. Available in different sizes and always with the right filtration fineness With these EREMA filtration systems it is the details that make the system really effective.
The way SW RTF technology works is to clean a small surface area of the filter screen by directing a flow of clean melt from the back of the screen. A high velocity is possible at the screen due to the small surface area of screen to be flushed, resulting in optimum cleaning efficiency.
Technical benefits
- Large active overall screen surface enables the processing of both high levels of contamination and surge contaminants in the melt
- Partial area backflushing with high cleaning efficiency through backflushing of individual screens
- Two opposing screens per carrier piston for balanced pressure distribution
- Lowest possible pressure fluctuations during screen change and backflushing
- Fully automatic, efficient and reliable backflushing mechanism for maximum screen service life, long screen change intervals and reduced screening costs
- Less labour required thanks to automatic backflush control
- High end product quality
- Low melt loss
