CoolDat® — autonomous cold-chain evidence

COOLDAT®

Helping food QA Managers get destination-specific cold chain data.

Getting destination-specific cold chain data at high resolution — for each destination, including within the end-customer infrastructure, whether a commercial or a residential kitchen — makes it possible for food producers to better synchronize what gets made, when it gets made, how it is packaged, where it goes, and ultimately, the resulting profit margins and the opportunities for upcycling or diversion.

  • •Item-level temperature logging
  • •RFID tag streaming over MQTT
  • •Predictive shelf-life ready data

FLAGSHIP USE CASE — TIME ABOVE SET-POINT

End-to-end excursion evidence for destination-specific best-before dates

Item-level temperature history with min/max set-points, alarms, and out-of-range intervals captured across the full journey — from producer to commercial or residential kitchen.

CoolDat® dashboard evidence trail — temperature chart with min/max set-points, highlighted out-of-range intervals, alarms, and timestamped excursion durations
  • •Per-item chart with min/max thresholds and highlighted excursions
  • •Resolved-state alarms with trigger and resolution timestamps
  • •Out-of-range intervals table: start, end, duration, and peak temperature
