New fridge that can store vaccines for 10 days

The refrigerator was designed by Wales-based sustainable energy firm True Energy using its patented Sure Chill technology.

Sure Chill enables energy to be stored efficiently and provides controlled cooling even during power cuts. It operates on less than five hours of power supply a day and, once charged, maintains constant cooling without any power at all.

In order to store vaccine safely it has to be kept at temperatures between 2 degree Centigrade and 8 degree Centigrade. Use of traditional forms of refrigeration in many parts of developing world is not an option as the power supply is poor and unreliable.

This power-free cooling phase can last over 10 days at ambient temperatures as high as 43 degree C—eight times longer than the nearest competitor. The innovative machine, which holds 103 litres of vaccines has passed the World Health Organisation’s stringent tests and is now listed on the organisation’s website, the company said in a release.

Millions of people in developing countries are in need of life saving vaccines. Often, the vaccinations have to be administered in very remote areas and in harsh conditions.
The new True Energy Vaccine Refrigerator is playing a vital role in the distribution of vaccines in some of the most isolated regions of the world, the release said.

Janos Mate, Senior Consultant to Greenpeace International, said: “The innovations that True Energy is making in solar powered vaccine cooling are proving to be hugely beneficial in parts of the world that have intermittent supplies of electricity.”
