Because vaccine refrigerators play such a critical role in protecting children from disease, their continuous operation is a top priority for health care providers at every level. That’s why the MetaFridge CFD-50 mains-powered and CFD-50 SDD solar-powered refrigerators are designed to monitor their performance, constantly measuring the vaccine chamber temperature, remaining holdover time, power availability and power use, allowing nurses, technicians, and supervisors to make informed decisions to protect vaccines.
