Permafrost Vacsafe portable cold box

The Sunamp Permafrost Vacsafe is a portable cold box for safely storing vaccine vials at -70 degrees Celsius for 24 days or more with no need for a direct power supply.

  • Maintains ultra-low temperature to store vaccines right up to the point of use
  • Allows transfer from bulk storage to outlying locations where vaccines are needed in small quantities
  • Reusable, refillable, or returnable for recharge, and recyclable
  • Compact and easily lifted by one person

Permafrost VacSafe Features


Keeps vaccines at -70°C, right up to the point of use. Other temperatures are available.

24+ Days

Maintains ultra-low temperatures for 24 days and more without the need for a direct power supply.


Small enough to be stored onsite in care homes and surgeries which means both required doses can be delivered in one journey.


Portable and robust for safe transportation by car, ideal for GPs and nurses visiting patients who cannot travel.

Less CO2

Releases less CO2 gas for safer storage, especially in confined spaces such as a storage cupboard, a car or on aircraft.


Uses up to ten times less dry ice and a eutectic version at -74C is also available should dry ice supply become an issue.


Refillable, rechargeable, recyclable, reusable. We guarantee to take the product back at the end of your use life and repurpose it.


The same VacSafe can be used with water ice for +2 to +8°C and other eutectic material cold packs to match any other vaccine.
