Vaccine Storage 50L, 2-8°C, Datalogger, Metafridge

MetaFridge™ vaccine refrigeration and its enabling ColdSafe™ technology are developed by Global Good. ColdSafe consists of an ice reservoir coupled to a thermosyphon wrapped around the vaccine chamber, passively providing safe and stable storage temperatures, and multi-day holdover.

MetaFridge Provides Reliable Cold Storage in Unreliable Power Conditions
Maintains vaccines at a stable 2-8°C temperature using patented ColdSafe Technology.
Allows 5 days of holdover at 43°C ambient temperature.
Can operate continuously on less than 2 hours of power per day at 43°C ambient temperature.
Requires less than 6 hours of power after installation to reach safe storage temperature with 2-3 days of holdover.
Grade A user-independent freeze protection.
Integrated Power Protection
Integrated protection during voltage spikes and brown-outs.
Internal voltage stabilizer allows compressor to use a wide range of voltage input.
Onboard Monitoring
Integrated 30 DTR display shows temperature and alarm history.
Holdover indicator allows users to proactively protect vaccines.
Visual and audible alarms for temperature excursions or improperly closed door.
Measures and records performance data to enable diagnosis of issues.
Optional telemetry module enables remote temperature monitoring and alerting.
Smart Design, Durable Construction
Upright and front-opening for user-friendly access.
Compact form factor and lifting handles allow easy transport.
Integrated plastic base prevents corrosion from wet floors.
Condenser guards and rodent-proof grates protect components.
Field Testing
More than 40 units were tested in Kenya, Nigeria, and Ethiopia for 3-6 months, all with remote monitoring.
Units were installed in both urban settings and rural areas typically served by SDD units.
99% of reported temperatures were between 2-8°C:
Temperature excursions were due to frequent or prolonged door openings and power outages of more than 7 days.
Local users were alerted by holdover indicator ahead of outage-related excursions and were able to relocate vaccines.
Units operating in Kenya with moderate ambient temperature averaged 45 minutes per day of compressor run time.
