deltaH Innovations, a London-based startup has come up with a super innovative solution that can render traditional drink refrigerators obsolete. The company has developed the world’s first self-cooling aluminium beverage can - the ‘Cool Can.’ Â

This innovative invention uses a smart blend of design and chemistry to deliver a refreshing chill at the press of a button. According to the company, the Cool Can can cool its liquid contents to approximately 6-7 degrees Celsius (42.8-44.6 Fahrenheit) and maintain that temperature for up to 45 minutes.
At first glance, the Cool Can resembles a regular aluminium beverage can, except for the prominent "power" button at its base. This button triggers a clever cooling mechanism. The base conceals a small water compartment, and when pressed, it releases the water into the gap between the can’s double aluminium walls. Within these walls are proprietary salts that react with the water, creating a rapid cooling effect that chills the beverage inside.
James Vyse, the Welsh founder of deltaH Innovations, explains that the Cool Can can take up to 10 minutes to reach a refreshing 6-7 degrees Celsius, depending on the surrounding temperature. Thanks to its double-layer design, the can keeps the beverage cool for around 45 minutes. To ensure users know when their drink is perfectly chilled, the Cool Can features a smart snowflake indicator that changes from white to blue once the ideal temperature is reached.
Alex Pell from The Evening Standard recently got a hands-on experience with the Cool Can and confirmed that it performs as promised. After pressing the button at the bottom and flipping the can upside down to ensure the water mixes with the salts inside the walls, he noticed the once-lukewarm can quickly turned cold to the touch, with condensation forming on its surface. While Pell didn't measure the exact temperature of the drink, he confirmed that it was pleasantly chilled.
While the Cool Can is still awaiting patent approval, deltaH Innovations claims they are already in discussions with major brands like Coca-Cola and Red Bull about integrating this technology into their canning processes. Although it’s too soon to predict if the Cool Can will revolutionize the beverage industry, the concept has certainly generated significant buzz.
Vyse is confident that the added cost to consumers will be minimal, particularly given the potential savings on refrigeration. Plus, the can is fully recyclable and usable in virtually any setting. The only notable drawback is that a 500ml Cool Can can only accommodate 70 per cent of the liquid compared to a traditional can of the same size, due to the internal cooling mechanism.
