Logistics & supply chain

Cold chain

Cold chain sells evidence that the chain never broke. Temperature data has to be continuous, traceable, and reportable—so when something goes wrong you can show which leg and which hour drifted.

How we see this industry

Zones and liability

Cold chain is not selling trucks and warehouses—it is proof the chain never broke. Shippers want continuity from outbound to receipt: temperature continuous, excursions alarmed, doors logged, product temperature at sign-off. After a quality event you prove which hour and which hop the deviation happened. We bind shipment, trailer or box, probes, door events, and sign-off photos. Sample rate, thresholds, offline backfill, and calibration interval are written in the design—not discovered after go-live as a point every ten minutes while a door sat open.

Segmented control

Cold store, cross-dock, and last mile are different zones; one rule set fails. Pharma, dairy, frozen, and fresh differ widely in thresholds and evidence. Zones configure by cargo class, with mixed-load warnings. Pre-cool complete before load is a gate so warm product does not “cool down” in transit on the chart. At sign-off the consignee can see the curve so a dispute has a shared fact.

Gaps and holes

Device offline and data holes are more dangerous than an occasional excursion—an excursion at least has a curve. A dropped probe, offline gateway, or a driver who switched the recorder off leaves an empty curve, which is no evidence. Offline rules, backfill windows, and hole alarms are separate, not one lamp mixed with over-temp. An out-of-calibration probe does not stand even if dense. Reports export by shipment for customer, insurer, and regulator, in a format fixed at acceptance.

Pre-cool then load

Load only after pre-cool. Warm cargo into a cold trailer makes a pretty curve and damaged product. Multi-temp mixed loads warn; pharma and ice cream do not share a threshold. Door time, defrost, and fuel stops stamp the curve so a customer reading a report knows where a spike came from. Insurer and shipper want different report shapes; export templates are acceptance items, not a rewrite after an incident.

One busy lane first

Go-live picks a high-frequency lane and one cargo class, running load-haul-sign before expanding. Hardware protocols and exception handling are most of the work and are measured on truck and store. Training is dispatch, drivers, and cold-store shift. A cold-chain system that works produces a continuous temperature and a sign-off on every shipment so claims are not a spoken argument about whether it was cold.

Typical scenarios

End-to-end monitoring

Cold room and trailer temperatures are sampled by the minute, with immediate alerts and a recorded response when limits are breached.

Delivery with proof

The temperature curve prints or pushes at sign-off and is filed as part of the delivery evidence.

Exceptions and accountability

Break events are located by time window and responsible party, giving claims and corrective action something to stand on.

Common blockers and how we handle them

Blocker

Temperature records are paper forms the customer does not accept

How we handle it

Devices collect automatically, data cannot be edited by hand, and reports export with device identifiers.

Blocker

Alerts fire with nobody acting, and the record is only seen afterwards

How we handle it

Alerts route to the on-duty person by severity, the response must be filled in, and overdue ones escalate.

Blocker

Everyone blames everyone and nobody can say which leg broke

How we handle it

Temperature curves and handover milestones align on the waybill timeline, making the responsible leg obvious.

Common system modules

Devices and collection

Cold room and in-vehicle device onboarding, sampling rates.

Temperature and alerts

Thresholds, alert severity, closed-loop response.

Waybills and monitoring

Waybills linked to temperature curves and milestones.

Delivery evidence

Sign-off sheets, temperature reports, photo records.

Tracing and reporting

Break analysis, compliance report export.

Assets and maintenance

Device register, calibration cycles, service records.

Delivery gates

  1. Scope

    Write zones, thresholds, sample rate, and required evidence by cargo class. Split cold store, linehaul, and last mile for this phase.

  2. Architecture

    Fix shipment-to-probe binding, offline backfill, and hole alarms. Confirm how vehicle, store temperature, and sign-off photos join.

  3. Build & integrate

    Connect load, haul, and sign on a real lane. Over-temp, door, and data-hole alarms stay separate; report-by-shipment is an acceptance item.

  4. Launch & operate

    Run one cargo class and one busy lane first. Train dispatch, drivers, and cold-store shift; put probe calibration in operations, then other lanes.
