ProSortX 4.0 makes setting up and using SORTEX N PolyVision easy and efficient, saving operators time thanks to the easy-to-use interface and offering deeper performance insights with a suite of digital connectivity tools.


High-intensity halogen lighting combined with a passive background ensures minimal calibration, which in turn ensures consistent sorting performance – even in varying ambient light levels.

Highest grade of plastic flakes

Adding a layer of assurance with PolyVision detection technology

The PolyVision technology uses transflective sorting to detect both clear and opaque polymer contamination by using their unique chemical signatures.
