Long-term vaccine cold box

Using patented Sure Chill technology, the Passive Vaccine Cooler keeps vaccines perfectly cool for up to 35 days with no power and absolutely no risk of freezing.

Sure Chill technology works by harnessing a unique property of water to provide 4°C cooling. While the pre-frozen ice packs provide the cooling energy, Sure Chill ensures that vaccines are never frozen and always safely stored between 2 – 8°C.
