SunDanzer’s 55-liter and 15-liter Battery-Free Vaccine Refrigerator solve a critical problem in the vaccine cold-chain by using solar direct-drive battery-free technology. SunDanzer’s medical refrigerators are built to serve off-grid parts of the world and are powered directly by the sun.
Vaccines save lives, but only if kept at the right temperature. Keeping these heat-sensitive vaccines at the right temperature can be a true challenge. Especially in remote and under-developed areas around the world that have limited or no access to an electric power grid.
Thermal Energy Storage and Holdover Time
The WHO requires a holdover time of 3 days at 43°C (110°F), but all SunDanzer models exceed 4 days for extra reliability.
Our solar powered medical refrigerators are lined with a proprietary phase change material (PCM) that maintains the required temperature range of 2°C to 8°C for vaccine refrigeration. Since these units have no battery, their useful life is a decade or more with no scheduled maintenance.
