Join those who already trust in Coolar’s innovative cooling system. Coolar aims to help doctors and health workers to preserve lifesaving medicine such as vaccines in a reliable and eco-friendly way, by providing close to carbon-neutral refrigerators that work without electricity.

Our Plan


The team at Coolar works hard to provide reliable cooling to regions without reliable or affordable electricity supply. With the Coolar system modern healthcare, vaccination and sufficient food supplies, can be provided to the developing world. Additionally, CO2 emissions are ten times lower than those of conventional refrigerators and without using harmful substances like cooling fluids, the Coolar system is completely non-hazardous. In 53 countries of the developing world, the Global Alliance for Vaccines and Immunisations (GAVI) has forecasted investment of $650 million for the purposes of cooling medical equipment.

Our system is already addressing two major issues, the overheating of medicine and vaccines, as well as food, and also the ability to be powered at off-grid locations. Although it depends on the vaccine and the size of the fridge, one fridge can generally cool vaccines for up to 4,000 people.
