Sure Chill

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.

A cool problem
From refrigerators that chill cans of cola in a hot Manhattan summer to those that store medicines and support blood banks in remote medical centres, refrigeration systems are essential to every part of people’s lives. But they’re inefficient. They need to have constant connection to power and, even in the best conditions, do not control temperature well.

But more than that, conventional coolers are in a constant battle with nature. While the sun heats the world vast amounts of energy are used to cool things down again. There is a need for a sustainable cooling solution that works. And keeps on working.

A simple idea
We started with water. It’s all around us but it’s also incredible. It has an amazing property that’s unique in the universe. At four degrees, water is at its heaviest. At four degrees it sinks. At any other temperature it rises. This scientific fact inspired us to create a new kind of refrigeration system. A seemingly intelligent system that adapts its temperature naturally so it automatically cools to the optimum temperature: a constant four degrees even without power.

An ingenious solution
Sure Chill is a brand new kind of cooling system. It doesn’t need a constant power source. In an on-grid situation with intermittent power, it works perfectly well. In an off-grid situation, where a solar panel may be used, a Sure Chill powered refrigerator doesn’t even need a rechargeable battery. It shouldn’t work but it does. And it works beautifully.

Water surrounds a Sure Chill refrigeration compartment. When it has power, the water cools and forms ice above the compartment leaving only water at four degrees cooling the contents. When the power is switched off, the water warms and rises while the ice begins to melt, keeping only four-degree water cooling the contents of the compartment. So it has its own internal and entirely natural energy store that maintains a completely steady temperature. The system can operate like this, without power, for days and weeks.

A beautiful future
Sure Chill is a cooling system that’s life-changing. And life-saving. Because the system is based on a law of nature, appliances using it are reliable and robust even in the harshest environments. Because a Sure Chill refrigerator is designed to work without power for many days, it can help get life-saving medicines to remote communities. And because it’s Smart Grid ready, in places with advanced power networks it can be powered whenever energy is cheapest, saving money for consumers and energy companies as well as saving resources for the planet.
