Our technology

Harnessing nature.

We start with water. It’s all around us and it’s incredible because its properties are unique in the universe. And it’s got the power to bring cooling to the world.

SureChill uses the unique properties of water. 
It’s most dense at 4°C and
when it freezes it stores a huge amount of energy.

SureChill innovative refrigerators contain walls filled with water.

Above or behind (depending on the model) the refrigerator compartment there is a small tank containing ice and water. This is our ingenious natural thermal energy store.

Water is most dense at 4°C.

This means it sinks to the bottom of the fridge. As it warms up, it floats back up to the thermal energy store, cools down and sinks again, repeating the cycle. Since all the water under or to the side of the compartment is about 4°C, it maintains a perfectly cool temperature throughout the fridge.

The ice acts just like a battery that never wears out.

It stores useful, high density energy any time that power is available. This unique method of cooling allows a constantly stable temperature, with or without power.

This natural phenomenon is the core of our technology, enabling our refrigerators to run for a long time with no (active) power supply.

It works perfectly with solar power, weak grids or any other intermittent or limited power sources.

 “It is my view that SureChill could make a huge contribution to childhood vaccination programs worldwide, and especially in poorer communities.”

Sir Richard Feachem, Professor of Global Health,
