Refrigeration of vaccines and food is problematic in parts of the world where there is no electricity or where the electricity supply is unreliable. In these regions vaccines are maintained by either kerosene or battery-based solar refrigeration. Kerosene refrigerators are also used for food preservation. There are significant concerns with both kerosene refrigeration and with the existing generation of solar-vaccine coolers.
It is expected that SolarChill technology will improve the cold chain for vaccines as well as provide more reliable refrigeration for perishable foods.
- SolarChill will provide a more reliable, safer and cleaner form of refrigeration than kerosene refrigerators.
- SolarChill technology will improve on existing solar-vaccine cooling technology by bypassing the use of conventional lead batteries which have proven to be a major obstacle to the uptake of solar technology in developing countries.
- SolarChill technology is environmentally friendly as it does not use any ozone depleting or potent global warming substances.
