Today is World Refrigeration Day!
We are marking World Refrigeration Day today because all too often we take the modern wonder of refrigeration for granted. Refrigeration has come a long way since our ancestors used snow and ice to keep things cool. Around 400 BC, the Persians were using the principle of evaporative cooling to make a ‘yakhchal’, meaning ice-pit. Since then, we have had various iterations of the ‘fridge’ as technology has evolved.
As with many inventions, no one person can claim credit for the refrigerator as we know it today – many scientists and engineers have had a hand in the cooling technology that keeps us safe by slowing down bacterial growth. And that is why the theme of this year’s World Refrigeration Day is #NextGenCooling, because technology never stands still, and refrigeration is constantly evolving.
Pioneering Dulas engineers
Engineers are always looking to innovate and improve, and we are incredibly proud of the Centre for Alternative Technology engineers who pioneered the solar powered vaccine refrigerator and established Dulas back in 1984. For many of us, refrigeration is a given, and we barely give a thought to the vaccinations that we received in infancy to protect us from diseases like tuberculosis, measles and polio. However, for those who live in areas with little or no grid connection, refrigeration and vaccination would be impossible without solar-powered cold chain equipment to keep vaccines at the required temperature, so that they remain effective.
Polestar factory: constantly innovating
The pioneering spirit and desire to innovate still exists today in Dulas, and in Polestar Cooling Ltd – our 100% owned refrigerator manufacturing facility in Bognor Regis. For twenty years, our Polestar engineers have specialised in the design and manufacture of refrigeration equipment for the medical, scientific, industrial, marine and construction sectors. In May of this year, we celebrated Polestar’s 20th birthday! Last year, we expanded production within the factory to meet growing demand, and since then we’ve been working hard to prepare orders being shipped to a growing number of countries around the world.
Cold chain is more important than ever
Today, as climate change affects temperatures all over the world, there is a very real threat to human health, especially in countries with weak health infrastructure. According to the World Health Organisation (WHO), increasing temperatures are expanding the areas where diseases such as malaria and dengue fever thrive. Extreme weather events and armed conflict also increase the likelihood of outbreaks of infectious disease. Cold chain is more important than ever – this network of cold rooms, freezers, cold boxes and carriers facilitate vital vaccination programmes in the most remote parts of the world, saving millions of lives every year.
