ENOS Multi-Barrier Technology System
The ENOS A100 "Sniffer" System is a vapor-analysis platform built to detect and remove consumer-returned contaminated refillable PET soft-drink bottles from RefPet and PRB lines.
Returned PET bottles are washed and refilled. Before refilling, each bottle is inspected for consumer-added contaminants. If contamination is detected, the bottle is automatically rejected and destroyed while compliant bottles continue through wash, clean, and refill operations. The ENOS A100 Multi-Barrier System is the production solution used to identify and reject those contaminated bottles before refill.
ENOS Sniffer and Multi-Barrier Technology
- Reduction of consumer complaints helps protect brand value.
- Strong gasoline, NOx, and PEx contaminated bottles are removed before Mass Spectrometer inspection, protecting final inspection performance before the bottle washer.
- ENOS Mass Spectrometer Module installs downstream of the ENOS A100 and ENOS Vision Module.
- Savings from reduced false rejects.
