Raymond Korea — FIX800 cold-storage monitoring with SCADA integration

Hello from Raymond Korea. This note explains FIX800 in a cold warehouse linked to a supervisory display. Charts illustrate human effects versus CO₂ and oxygen.

Cold stores are confined spaces; dry ice inventory can drive CO₂ up and O₂ down—both must be managed.

This site monitored oxygen and carbon dioxide together. Normal air holds ~21% oxygen; adding CO₂ dilutes oxygen and affects workers.

FIX800 inside the chamber streams live readings; the beacon alarms when limits are exceeded.

Outputs include RS-485, 4–20 mA, and relay contacts for BMS/PLC integration.

The control-room mimic shows six cold rooms at a glance.

Data loggers can archive trends for audits. FIX800’s flexible I/O makes many architectures possible. Thank you for reading this cold-storage case study.
