Metafridge 2-8°C Refrigerator Series

Metafridge 2-8°C Refrigerator Series

Reliable Vaccine Storage for Unstable Power Environments

Jointly developed by AUCMY and Global Health Clubs under the Gates Foundation, Metafridge solves the problem of vaccine storage in areas where power is available for less than 4 hours a day. These units can maintain safe storage temperatures for over 5 days after a total power failure.

Product Advantages

• • Long-Term Preservation: Both models keep temperatures between 2-8°C for over 5 days after power-off under an environmental temperature of 43°C.

• • Rapid Cold Accumulation: The devices can realize safe and stable storage temperatures after being supplied with power for only 3 hours in a single day.

• • High-Standard Safety: Rated as WHO Grade A anti-freezing.

• • Advanced Monitoring: Includes a 30-day temperature record and supports remote temperature monitoring and settings.

• • Alert System: Equipped with audible and visual alarms to notify users of abnormal storage temperatures.

• • CFD-50 SDD Special Features:

  •     • Battery-Free Solar Drive: Utilizes a solar direct drive compressor with high refrigerating efficiency, eliminating the need for batteries.

  •     • Intelligent Forecasting: Analyzes temperature data from the past 30 days to forecast preservation days after power-off.

  •     • Hybrid Power Switching: Automatically switches between solar and electric energy based on light intensity.
