Medicines and vaccines must remain within their specified temperature limits during transport. Portable medical refrigerators and qualified insulated transport systems help maintain the cold chain. This guide explains the main differences and what to check before choosing equipment.
Why choose a portable medical refrigerator?
Temperature-sensitive medicines, biological samples and reagents require controlled transport conditions. A medical refrigerator provides active cooling while powered and operated within its rated conditions. An ordinary food cooler is not a substitute for a transport system qualified for the products being carried. Browse our portable medical refrigerators.
12/24 V and 220 V power options
- 12 V or 24 V DC: vehicle power during transport, where supported.
- 220 V AC: mains power at a pharmacy, clinic or laboratory, directly or through the specified adapter.
- Backup power and automatic switching: availability depends on the model and configuration.
Check the actual input ratings, supplied cables and adapters, and the procedure for switching power sources. Plan for loading, unloading and any period when the vehicle is parked or disconnected.
Maintaining +2 to +8 °C in transit
For vaccines whose instructions specify refrigerated storage, the usual range is +2 to +8 °C. Other products may require different conditions. Always follow the product manufacturer's current storage and transport instructions. Choose equipment rated for the expected ambient conditions and monitor the temperature throughout the journey. Some refrigerator models also offer freezing, but that does not make freezing suitable for every medicine or vaccine.
Active refrigerator or insulated transport container?
- Portable medical refrigerator: active temperature control while powered, within the manufacturer's operating limits. Check suitability for your route and load.
- Qualified insulated container with the specified packout: passive temperature control for a defined duration and ambient profile, without an electrical supply. See our medical transport containers and cases.
The two approaches can be combined for vehicle transport and the final handover. The complete process, including transfer between containers, must meet the required temperature conditions.
Capacity and portability
Choose usable capacity for the shipment size, packaging and route. Check external dimensions, weight, handles and safe positioning in the vehicle. Leave the clearances and internal airflow space specified by the equipment manufacturer.
Temperature monitoring during transport
Use an appropriate temperature monitoring device for each transport container. A temperature data logger records conditions during the journey and supports reporting. Check probe placement, recording interval, calibration documentation and access to the readings or alarms.
Selection checklist
- Required temperature range: based on the products' instructions.
- Power: compatible DC and AC inputs, adapters and changeover arrangements.
- Usable capacity: shipment, packaging and route requirements.
- Monitoring: display, alarms and data logger compatibility.
- Power interruptions: documented holdover or backup arrangements under relevant conditions.
- Weight, dimensions and handling.
Frequently asked questions
How does a portable refrigerator differ from an insulated container? A refrigerator actively controls temperature while powered. A qualified passive system maintains its specified range for a documented duration with the prescribed packout.
Which power supply does it use? Depending on the model, vehicle DC power and mains AC power may be supported. Confirm ratings and adapters before ordering.
Can it transport vaccines? Only when the equipment and transport process meet the particular vaccine's instructions. Monitor temperature throughout transport.
When is an insulated container sufficient? When its qualified duration, temperature range, packout and ambient limits cover the complete route, including possible delays.
