Sure Chill

Perfectly cool fridges without power

It’s not overstating the case to say Sure Chill is revolutionary. How else would you describe a fridge that transforms the heat of the sun into constant cooling – both in the day and the night – without the need for a battery?

Sure Chill supplies medical refrigerators for the storage of temperature sensitive medicines and vaccines, and fridges for homes and businesses in harsh and remote locations where the power supply is absent or unreliable. Sure Chill’s patented cooling technology uses water as a natural energy store and its fridges can stay perfectly cool for days.

After first developing its technology in 2009, Sure Chill launched its first product to market in 2011. Sure Chill’s customers today include UNICEF and Médecins Sans Frontières.
