Established in 2007, ENOS Engineering is a leading provider of inline real-time production inspection systems for the beverage and food industry.

Returnable bottles in Latin America pass through ENOS inspection

A100 Multi-Barrier protection.

The ENOS A100 inspects returned PET bottles before washing and refill, then removes bottles that may carry consumer-added contaminants. For most lines, A100 is the foundation: a complete protection station designed to reduce complaints, protect product quality, and keep operators moving.

Before the washer

At-source protection for returned bottles.

A100 replaces manual sniffing with a repeatable inline check, helping plants find contaminated bottles early and keep clean bottles moving toward production.

  1. 1 Returned bottles arrive before wash and refill.
  2. 2 A100 inspects each bottle without contact.
  3. 3 Suspect bottles are automatically removed from the line.
Configurations

Two protection levels, one architecture.

Start with the A100 sniffer alone, or move to maximum protection with vapor preparation, final verification and controlled rejection.
