Keeping it chilled

James Vyse, founder and CEO of DeltaH Innovations, talks CanTech International through a newly developed can with self-cooling capabilities.

UK-based DeltaH Innovations is on a mission to improve the way consumers enjoy cold drinks on-the-go with its patent-pending, fully recyclable can that rapidly cools beverages anywhere, without the need for refrigeration. CanTech spoke to DelaH founder and CEO, James Vyse, about the Cool>Can’s key features.

Could you explain how the cooling technology works?

A discreet button mechanism, highlighted in black, is securely attached to the base of the can. To activate the cooling process, the user simply turns the can upside down and presses the button for approximately five seconds. This triggers an instant cooling reaction within a sealed inner chamber, rapidly reducing the beverage’s temperature.

Within seconds, the drink cools with a 15°C temperature drop, delivering a refreshingly cold beverage, comparable to a beverage taken straight from the fridge or even colder.

The cooling effect lasts for up to 30 minutes, allowing consumers to enjoy their drink at the perfect temperature, anytime and anywhere – without the need for refrigeration.

This technology prioritises both safety and quality. At no point does the cooling reaction encounter the liquid, ensuring that the beverage’s flavour, composition and integrity remain entirely unchanged.

What material(s) is the packaging made from?

The button mechanism is composed of recycled PET plastic, while the inner chamber is crafted from aluminium, a material chosen for its exceptional thermal conductivity.

Aluminium’s superior heat transfer capabilities allow for rapid and efficient cooling, ensuring that the beverage reaches an optimal temperature in just seconds. Additionally, aluminium is lightweight, durable, and recyclable, making it an environmentally responsible choice that aligns with DeltaH’s commitment to sustainability.

By integrating aluminium into the Cool>Can’s design, we not only enhance performance but also contribute to the circular economy, reducing waste and supporting the continued reuse of materials. This ensures that our technology remains both highly effective and eco-conscious, delivering high performance without compromising on environmental responsibility.

What can sizes is it compatible with?

The Cool>Can mechanism is designed to be universally compatible with all standard beverage cans, ensuring seamless collaboration across a wide range of drink options.

Whether it’s soft drinks, energy drinks, iced coffee or alcoholic beverages, the cooling technology works effortlessly to provide a perfectly chilled experience each and every time.

This versatility makes the Cool>Can an ideal solution for brands and retailers looking to enhance their product offerings without the need for specialised packaging. Consumers can continue to enjoy their favourite beverages in familiar can formats, with the added benefit of instant cooling at the push of a button. By maintaining compatibility with industry-standard cans, we ensure ease of adoption, minimal production adjustments, and widespread accessibility, bringing game-changing cooling technology to the global beverage market without disruption.

Does the technology affect the recyclability of the can?

At DeltaH, sustainability is at the core of everything we do. Our cooling components are entirely safe for the environment and have been scientifically proven to function as a natural fertiliser for plants. Once the beverage has been consumed, the button mechanism can be easily removed by the user, ensuring that any residual contents within the can remain completely harmless to the environment. Additionally, the button mechanism, made from recyclable plastic, and the aluminium chamber itself will be disposed of through standard recycling processes.

Recyclability is just one of the many sustainability milestones DeltaH has achieved. The cooling industry, including refrigeration, currently accounts for approximately ten per cent of global CO2 emissions and ten to 15 per cent of worldwide electricity consumption. The
Cool>Can presents a groundbreaking opportunity to significantly reduce this impact by eliminating the need for refrigeration in canned beverages.

Retailers that stock DeltaH products will not only lower their electricity usage and carbon footprint but also free up valuable in-store space previously occupied by refrigeration units.

Who is the ideal target audience?

No one enjoys a warm canned drink, which is why we believe this innovative cooling mechanism is designed for everyone.

However, the Cool>Can is particularly well-suited for those with on-the-go lifestyles. Busy commuters can enjoy a perfectly chilled drink without needing access to a fridge, while outdoor enthusiasts, whether hikers, campers, or beachgoers, can count on refreshment wherever their adventures take them. Event attendees, from music festivals to sporting events, will appreciate the convenience of an instantly cold beverage without relying on bulky coolers or venue refrigeration.

Additionally, the Cool>Can appeals to discerning consumers who seek more than just a standard drink, offering an elevated drinking experience with a unique and interactive cooling feature. Whether browsing store shelves or looking for a premium beverage innovation, this technology delivers a new level of convenience, sustainability, and refreshment.

Where do you plan to distribute the product?

As we approach our highly anticipated market launch, planned for the coming spring, we are actively engaging with major retailers and leading beverage brands to bring the Cool>Can to consumers worldwide. These ongoing discussions mark a significant step forward so expect to see Cool>Can technology on the shelves of supermarkets, as well as in top restaurants, bars, music festivals, and entertainment venues. Whether you’re grabbing a drink on the go or enhancing your dining and social experiences, we’ll be sure to keep your drinks cold anytime, anywhere and very soon.
