Real world application
In July 2025 UNICEF shipped over 500 000 doses of pneumococcal vaccine by sea from Belgium to Côte d’Ivoire. Using insulated containers with monitoring devices, the sea route reduced greenhouse gas emissions by 90 % and halved freight costs compared with air transport while maintaining vaccine quality. This case shows that careful route planning and sustainable modes can improve efficiency without compromising safety.
Key components of a cold chain system
Cooling systems
Cooling systems rapidly reduce product temperatures to safe levels. Blast freezers, refrigerated containers and liquid nitrogen systems quickly bring perishables to their target temperature. For example, blast freezers preserve texture and flavour by lowering temperature rapidly before storage or transport. Selecting the right cooling method depends on your product’s sensitivity and time frame.
Storage facilities
Refrigerated warehouses and cold rooms maintain consistent temperatures for extended periods. Larger facilities often contain smaller cold rooms to accommodate various temperature zones. Look for storage sites with backup power and integrated temperature sensors to prevent fluctuations during outages. Modular cold rooms can be scaled up during peak demand, such as harvest seasons or vaccine campaigns.
Transport vehicles
Refrigerated trucks, ships and aircraft (reefers) are designed to maintain controlled environments during transit. Modern reefers use advanced insulation, active refrigeration units and GPS enabled telematics to monitor conditions. Refrigerated light commercial vehicles (LCVs) are gaining popularity because they combine fuel efficiency and urban accessibility. When selecting a carrier, verify that it can handle the required temperature range and has contingency plans for delays.
Monitoring and control
Continuous monitoring is the backbone of the cold chain. Sensors, data loggers and IoT devices provide real time or historical temperature data. IoT enabled sensors transmit data via Wi Fi, cellular or LoRaWAN networks and offer immediate alerts. GPS trackers combine temperature and location tracking to provide full visibility and route optimization. Implementing these tools allows you to take corrective action before a minor deviation becomes a major loss.
Packaging and insulation
Smart packaging solutions—such as containers with built in sensors, vacuum insulated panels and phase change materials—can maintain precise temperatures for 48–72 hours while transmitting live data. Multi temperature zone shippers divide a single container into compartments with different temperature ranges, enabling mixed loads of frozen and chilled goods. Sustainable packaging materials (biodegradable liners, reusable pallets) reduce waste and meet regulatory expectations.
Data management and compliance
Documentation and traceability are crucial. Blockchain technology creates tamper proof logs of temperature and handling events, simplifying audits and boosting consumer trust. In addition, Good Distribution Practice (GDP) regulations require businesses to maintain accurate temperature logs and calibration records. Automated systems, including digital checklists and compliance management software, help you stay audit ready and avoid fines.
