The Science and engineering behind SMILE

Our patented SMILE cooling system is freeze-free and fail-safe. It aims to reduce wastage to below 5%.  


SMILE maintains vaccines or bio-samples at a stable temperature for 3 to 6 days even when in use. We achieve this by using a bespoke SMILE icepack and our patented air-locking system. This means that we do not need electricity or external power when in use and SMILE keep these products cool for much longer. For outreach activities, SMILE's all-in-one backpack improves vaccination efficiency and minimises breakage over tough terrains.
