How Does The Product Work

How Do Self Heating Cans Work?

Within the self-heating can, there are two compartments. The first contains coloured water and Calcium Oxide (Quick Lime), and the second contains 205 ml of ready-to-drink beverage. Both compartments are separated from each other and never in direct contact. When pressing on the transparent container on the bottom of the self-heating can (after removing the bottom lid), an aluminium foil inside breaks allowing the water to come into contact with the Calcium Oxide. An exothermic natural reaction then starts which generates heat. The heat is then transferred to the beverage through the tinplate of the inner can which separates both of these compartments. It takes 3 minutes in total, to increase +42°C above ambient temperature.

What is an Exothermic Natural Reaction?

An exothermic reaction releases energy, usually in the form of heat or light when chemicals come into contact. The reaction between Water and Calcium Oxide will result in Calcium Hydroxide and heat. Our self-heating cans will reach its peak heat after 3 minutes.

What is Calcium Oxide?

Calcium oxide (CaO) is also commonly known as Quicklime and is a widely used chemical compound primarily in construction. It is a white rock at room temperature. Uniquely, when calcium oxide reacts with water to create calcium hydroxide, the reaction releases a lot of energy in the form of heat. Since it is a non-combustible material, the chemical reaction is ideal for heating your beverages and soups inside your self-heating can.

Why Does Steam Appear?

Steam will come out from the bottom of the can around 15-30 seconds after you press down on the can. This is a normal part of the self-heating process. The natural exothermic reaction between water and calcium oxide generates steam. Once you see the steam turn the can to the right side up again and stir softly for a few seconds, and your favourite drink is hot in 3 minutes.

How Hot Will My Product Get?

After 3 minutes the beverage or soup inside the self-heating product has increased its temperature by approximately 42˚C over its initial ambient temperature.

That means that if the storage temperature of your can was 20˚C, then the product will be a delicious 62˚C. 

We suggest that you store the products between 5˚C-30˚C for the optimal product and for the reaction to work as intended.

How Long Will My Self Heating Can Stay Hot For?

Your beverage will remain hot for about 20 minutes after activation. The temperature will reach its peak after the first 3 minutes.

What If My Product Doesn’t Get Hot?

Please make sure that you follow the instructions that are on your label, or the instructions video when scanning our QR Code.

After you have pressed down on the bottom of the can and you notice that all the blue water has disappeared, please wait until steam appears. This can take anywhere between 10-30 seconds. When the steam appears, make sure that you flip the can over and wait 3 minutes until your drink is ready and hot.

If you have followed the instructions and still have issues with the product, please contact us directly with the issue and we will be happy to help.
