Disrupting the entire cooling industry with new technology that doesn’t require a constant power source, enabling refrigeration of food products, life-saving vaccines, and more.

Sure Chill has developed and patented a unique cooling technology that enables cooling equipment to maintain a constant temperature without constant power. The technology acts like a rechargeable battery but is entirely natural, using no chemicals or electrodes. This makes it perfect for areas of the world with intermittent power or no power at all, as it can be teamed with solar. Their first product, a vaccine refrigerator, can stay cool for 12 days without power in 43°C and has achieved sales in 49 countries. The company works closely with the World Health Organization and UNICEF and has received $1.5 million from the Bill & Melinda Gates Foundation. Sure Chill is also working with some of the world's largest brands to develop solutions within home refrigeration, food and drink, and logistics —all of which contributed to the government of Dubai's decision to choose Sure Chill as one of the technologies most likely to change the world in the next 20 years.
