A vaccine cold chain monitoring system earns its place on the night a compressor fails and someone still reaches the store in time. We build that system for you - loggers inside every ILR and deep freezer, gateways across your depot and clinic network, and alert rules that reach the right person.
Loggers and probes selected for ILRs, walk-in coolers, deep freezers and ultra-low temperature units alike.
Escalation ladders moving from the cold chain handler to the supervisor when nobody responds.
Every excursion logged with duration, magnitude and action taken, ready for an audit or batch decision.
One monitoring view across depots, district stores, clinics and transport.
Device selection, connectivity, alerting and reporting are one problem, not four. We supply and install the loggers and gateways, build the monitoring software, and support the network afterwards.
✓ WHO PQS-aligned logger and probe selection per equipment type
✓ Glycol-buffered probes reflecting vial temperature rather than air
✓ ILR, deep freezer, walk-in cooler and ultra-low coverage
✓ Gateway and connectivity design for low-signal rural sites
✓ Configurable thresholds with duration filters suppressing door-opening spikes
✓ SMS, voice call, mobile app and email escalation by role
✓ Power failure and mains outage detection at each site
✓ Acknowledgement capture with corrective action recorded per alarm
✓ Bluetooth loggers inside vaccine carriers and cold boxes
✓ Trip-level temperature history downloaded on return to store
✓ Reefer vehicle monitoring with door and location events
✓ Conditioning and ice pack compliance recorded per session
✓ Calibration certificate tracking with due-date alerts per device
✓ Excursion register with duration, magnitude and disposition decision
✓ Equipment uptime and alarm response time by site
✓ Programme review reports exported for state immunisation officers
Devices are chosen for the site, the temperature band and the network there. A logger that suits a district store can be useless at a sub-centre.
Representative outcomes from vaccine cold chain deployments across public and private networks. Figures are indicative ranges typical of this solution type and must be confirmed against your own baseline before publication.
✓ Continuous 2-8 C visibility extended across monitored sites
✓ 70-85% faster response to compressor and power failures
✓ Manual twice-daily temperature registers withdrawn at monitored sites
✓ Excursion evidence available for every dispatched consignment
✓ 40-60% reduction in product written off after excursions
✓ Audit responses assembled from system records, not logbooks
✓ Alarm fatigue reduced after threshold and delay tuning
✓ Overnight and weekend failures detected within minutes
✓ Calibration compliance tracked centrally across monitored units
What a cold chain manager and a state immunisation officer will want proven. Targets are design goals agreed in writing beforehand.
Share of expected readings actually recorded and delivered to the central platform.
Target: >99% of readings
How we get there: Protected by on-device storage and store-and-forward gateways that backfill after an outage.
Time from an excursion alarm being raised to a named person acknowledging it.
Target: Under 15 minutes
How we get there: Driven by escalation ladders that move up a level when nobody responds.
Share of alarms caused by door openings, defrost cycles or probe placement, not real excursions.
Target: <5% of alarms
How we get there: Reduced by duration filters, buffered probes and thresholds tuned per equipment type.
Share of deployed loggers holding a valid, in-date calibration certificate at any given time.
Target: 100%
How we get there: Maintained by due-date alerts and a planned replacement pool, not reactive recalls.
Deployment moves district by district, so support load stays manageable as the network grows.
We list every storage point, equipment type and temperature band, check power and mobile signal at each site, and record who responds to an alarm.
Logger, probe and gateway selection, threshold and escalation design and all integration points are documented and signed off before any device is ordered.
One district or depot runs live for a full monitoring cycle, so alarm volumes, response behaviour and connectivity gaps are seen before network-wide rollout.
Remaining sites are commissioned, handlers and supervisors are trained on acknowledgement and corrective action, and the system moves into an agreed support arrangement.
Why immunisation programmes and vaccine distributors ask us to engineer monitoring rather than buy loggers off a catalogue.
Probe type, buffering, battery life and connectivity are selected against the equipment and signal conditions at each location, not standardised statewide for procurement convenience.
We tune thresholds and duration filters during the pilot so handlers keep answering alarms. A system that cries wolf is worse than none at all.
Mounting, probe placement, gateway commissioning, calibration certificate management and device replacement are part of the scope, not left to site staff to arrange.
Excursion registers, uptime summaries and calibration status are produced in the formats programme reviews and regulatory audits ask for, not as dashboard screenshots.
It is a system of temperature loggers, gateways and software that continuously records the storage and transport temperature of vaccines and raises alerts when it moves outside the permitted band. A vaccine cold chain monitoring system covers ILRs, deep freezers, walk-in coolers, ultra-low units and last-mile carriers, and escalates alarms until someone responds.
No. We supply and install devices, but the system is engineered for your network. A requirement study covers every storage point, equipment type, temperature band, power reliability and who responds to an alarm. Thresholds, escalation ladders and reports are built from that.
Standard vaccine storage at 2-8 C, freezer storage down to minus 25 C, and ultra-low storage at minus 70 C and below. Probe type, buffering and logger specification change across those bands, so devices are selected per equipment type after the survey.
Yes. Loggers, probes, gateways, mounting hardware and network connectivity are supplied, installed and commissioned as part of the project, with WHO PQS alignment where the programme requires it. Calibration certificates are tracked, and replacement devices are held so no site goes unmonitored.
By making alarms rare and real. Duration filters suppress the brief spikes caused by door openings and defrost cycles, buffered probes reflect vial temperature rather than air, and thresholds are tuned per equipment type during the pilot.
Yes. Mains presence is monitored at each site, so an outage raises an alert before the temperature has moved. This matters most in ILRs with holdover capacity, where a failure caught early is corrected without product loss.
Yes. We build interfaces to ERP, warehouse and vaccine stock management systems, so temperature and excursion data sit alongside batch and stock records. Missing connectors are built within project scope.
Yes. Government programmes frequently require data to sit on state or departmental infrastructure, and on-premise, private cloud and hybrid deployments are all supported. Gateways buffer locally either way, so a site keeps recording during an outage.
A single district or depot pilot is normally live within six to ten weeks of requirement sign-off, depending on device lead times, calibration and site access. Network-wide rollout then proceeds district by district.
The system moves into an agreed support arrangement covering defined response times, device replacement and repair, calibration cycle management, connectivity troubleshooting and refresher training for handlers. Alarm rules are reviewed periodically as staffing changes.
