1. 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 solid 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 combustable material, the chemical reaction is ideal to heat your beverages inside a self-heating can.
2. 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. In our self-heating cans, they will reach its peak heat after 3 minutes.
3. WHAT IS +42° SELF HEATS?
+42º Self Heats is a range of premium hot beverages delivered in a self-heating can. Once the can has been activated, the self-heating can technology will heat the beverage without the need of any electrical device, which means that you can have a hot drink no matter where you are anywhere, any time!
4. HOW DO SELF-HEATING CANS WORK?
Within the self-heating can, there are 2 compartments. The 1st contains coloured water and Calcium Oxide (Quick Lime), and the 2nd contains 205 ml of the ready to drink beverage. Both compartments are separated from each other and never in direct contact. When pressing on the bottom of the self-heating can (after removing the bottom lid), an aluminium foil inside breaks allowing the water to get in 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.
5. DOES THE REACTION TOUCH MY DRINK?
No. The main compartment containing the beverage is safely insulated from the reaction compartment so the self-heating reaction and your beverage are never in contact.
6. 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 the right side up again and stir softly for a few seconds, and your drink is hot in 3 minutes.
7. 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.
