3D twinPharma warehouses · 2–8 °C to −80 °C
The Autowhat pharma cold chain digital twin is a live 3D model of your pharma hub: cold rooms, freezers, QC release, pick and pack and reefer docks. Each excursion is tied to the batches inside it and sent to the person who has to act.

Operational AIFictional pharma distribution hub with sample data — your twin is drawn from your own site and systems.
02Definition
Nine areas of a pharma warehouse, each with what the twin draws, the systems it reads and the conditions it raises before a deviation is written.
A pharma cold chain digital twin is a live, to-scale model of a pharmaceutical warehouse and its shipments that stays in step with the temperature sensors, WMS, QC records and reefer data the site already produces. It shows every storage unit, batch and dispatch in place, links each excursion to the stock it affects, and routes the action to the person responsible.
03Measures
Each number on the twin traces back to the system and the minute it came from, so QA can quote it in an investigation.
| Measure | What it tells you | Where it comes from |
|---|---|---|
| Storage units in range | Share of rooms, freezers and racks inside their labelled band right now. | Temperature sensors via ColdWatch |
| Open excursions and duration | How many units are outside their band, for how long and at what peak. | ColdWatch excursion register |
| Time to acknowledge an alarm | Minutes from alarm to a named person accepting it, by escalation level. | Alarm and notification log |
| Mean kinetic temperature (MKT) | One temperature expressing the cumulative thermal stress on stock over a period, weighted towards warm spells. | Calculated from sensor history |
| Dock-to-cold time | Minutes from reefer door open to the last cold pallet inside a 2–8 °C room. | Dock schedule, WMS putaway scans |
| Quarantine occupancy and age | Pallets awaiting QC or QA decision, and how long the oldest has waited. | WMS status and QA register |
| Release cycle time | Hours from GRN to release of a batch as saleable stock. | WMS, QC and QA records |
| Near-expiry stock and FEFO breaks | Value of stock under 90 days to expiry, and pallets picked out of first-expiry order. | WMS batch and pick data |
| Reefers pre-cooled at load | Share of reefers below their set point before the first box was loaded. | Reefer telemetry, dock checklist |
| Delivered in range | Share of shipments whose loggers stayed inside the band from dock to receipt. | Shipment loggers, UltraCold for −80 °C |
| Calibration on time | Sensors calibrated before their due date, against all sensors in use. | Calibration register |
04Problems it removes
Four failures that turn a short temperature drift into a deviation, a destroyed batch or an audit observation.
The twin joins the room's sensors with WMS stock, so an excursion arrives with the batches, quantities and value in that room. Those batches go on QA hold in the same record, without a phone call to the warehouse.
Each room and freezer is trended forward, so a unit heading for its limit shows an estimated time to breach hours ahead. The twin also points to the likely cause, such as a door, a condenser or a loading pattern.
Quarantine pallets show what is missing for each batch: sampling, CoA or a signature. QA sees which batches can be released now and which hospital orders are waiting on them.
Dispatch is gated on the reefer's own temperature and on packed gel-pack counts, so loading waits until the box is cold. The shipment carries live loggers to delivery and the record stays with the batch.
05A shift on the twin
Three moments from the sample hub in the 3D view above. Times, rooms and values are illustrative.
Air in CR-2 crosses 8 °C while product probes are still at 7.2 °C. The twin opens the excursion, puts the nine batches inside on QA hold and escalates to the warehouse manager when the shift supervisor misses the ten-minute window. QA receives the impact assessment with peak, duration and MKT.
The reefer at dock 3 reads 11.4 °C, so the dock stays locked until pre-cooling brings the box under 8 °C. The dispatch lead moves the wave to dock 2, where the next reefer is already at 4.2 °C.
U-05 is at −76.8 °C with the compressor at 96% duty and rising 0.4 °C an hour. The twin estimates when it reaches −70 °C and suggests moving its three batches to the spare cabinet; the facility engineer and QA head plan the transfer before the evening shift.
06How it is built
Five steps that turn a drawing, a sensor list and the WMS into a live model QA and operations both use.
Trace the warehouse from its layout drawing or a satellite view: rooms, racks, freezers, docks, utilities and the yard, to scale.
Place each air sensor, product probe and door contact where it is installed, using the temperature mapping study, with its band and alarm limits.
Read existing sensors over BACnet/IP or Modbus TCP, and join WMS stock, QC and QA records, reefer loggers and GPS on batch number.
Agree with QA which conditions raise an alarm, who acts at each escalation level, and what puts a batch on hold.
Replay excursions and shifts on the model, close CAPAs against what happened, and tighten rules as history builds.

FAQQuestions about pharma cold chain digital twins
What buyers in QA, warehousing and supply chain ask before a briefing, answered directly.
A pharma cold chain digital twin is a live 3D model of a pharmaceutical warehouse and its shipments, fed by the sensors, WMS, QC records and reefer data the site already has. It shows every storage unit and batch in place, links excursions to the stock they affect and sends each action to the person responsible.
It reads temperature, door and equipment data every minute and places each reading on the room, rack or freezer it comes from. It joins that with WMS stock and QA records on batch number, trends each unit forward, and raises an alarm with the affected batches and the owner when a band is at risk or crossed.
The main use cases are excursion impact, early warning and faster release. A pharma cold chain digital twin links each excursion to the batches it affects, warns before a cold room or freezer breaches its band, shows what each quarantined batch is missing, gates reefer loading on temperature, and traces any batch from receipt to the receiving hospital for audits.
A temperature monitoring system records readings and raises alarms for each sensor. The twin uses those readings, from a system such as ColdWatch, and adds what is stored where, what is awaiting release, which reefer is loading and what the power and refrigeration plant is doing, so the alarm comes with its consequence.
No. Lane simulation models a shipment's thermal behaviour to choose packaging before it travels. An operational twin mirrors the warehouse and live shipments as they run today. Both are called digital twins; this page describes the operational kind, which works on live data rather than test scenarios.
Usually not. Many qualified cold rooms and freezers already have sensors that speak BACnet/IP or Modbus TCP, and the twin reads them as installed. New sensors are added only where the temperature mapping study shows a gap, such as the top levels of an ambient rack or a product probe in a busy cold room.
Yes, it supports the records GDP expects: continuous monitoring, excursion records with duration and peak, alarm acknowledgements with comments, calibration tracking and batch traceability. ColdWatch keeps an append-only ALCOA+ audit trail for five years and delivers IQ, OQ and PQ documents. Your QA team still owns validation and the compliance decision.
It opens the excursion the moment a band is crossed, records its duration and peak, and lists the batches inside that unit. Those batches go on QA hold, and the alarm escalates by WhatsApp, SMS and email until someone acknowledges it. QA gets an impact assessment with MKT to support the disposition and CAPA.
Yes. Freezer rooms and ultra-cold cabinets appear on the same model as cold rooms, each with its own trend and time to breach. For −80 °C shipments, UltraCold adds 22 dispatch controls, dual sign-off by two different people, dry-ice planning per lane and two live loggers to delivery.
Yes, for vaccine warehouses and distributors. Vaccine stock at 2–8 °C or frozen is shown by batch in its room, with excursions linked to the vials affected and a trace from receipt to the receiving hospital. Government immunisation programmes in India run on their own national platform, so this fits manufacturers, distributors and private hospital chains.
It needs the site layout, the sensor list with bands, and access to the WMS or ERP for stock by batch. QC and QA records, the calibration register, reefer loggers and utility meters add release status, equipment health and transit visibility. It can start with sensors and stock, then add the rest.
The first site is scoped in a 30-minute working session on your own data. A typical hub runs in phases: layout and sensors in the first two weeks, systems connected over the next two, and the whole hub live in the second month. ColdWatch itself goes live, qualified, in about four weeks.
Autowhat prices the twin per deployment after a 30-minute working session; there is no public list price. Cost depends on the number of sites and storage units, the systems to connect and whether sensors are needed. It runs on managed cloud, in your own VPC or on-premises, and the data stays yours.
Pharma manufacturers, C&F agents, distributors and 3PL cold stores use it, with each role watching its own part. QA heads use it for excursions, holds and release. Warehouse managers use it for docks, quarantine, FEFO and dispatch. Facility engineers watch condensers, freezers, DG sets and calibration, and supply-chain heads track delivered-in-range across warehouses.
