Design Specifications

Sure Chill works on the principle that water is at its densest at 4°C. Water surrounds a Sure Chill refrigeration compartment. When power is supplied to the refrigerator, the water cools and ice is formed above the compartment leaving only water at 4°C and thus cooling the contents. When the power is switched off, the water warms and rises while the ice begins to melt. This keeps only water at a 4°C cooling the contents of the compartment keeping temperatures at 4 to 5°C. The temperature variation within the cabinet is less than 1°C. The solar ‘direct drive’ model of the Sure Chill vaccine refrigerator doesn’t need a battery to maintain cooling performance overnight. In severe power outages, it can keep vaccines at safe temperatures for ~10 days or more at 32°C ambient, and even longer at lower ambient temperatures. Dimensions: 89 cm x 76 cm x 185 cm Power consumption: Solar array 200W to 370W depending on geographical location Minimum rated ambient temperature: 5°C Vaccine storage capacity (litres): 99L Weight: 145 kg
