Q. What is an ice lined refrigerator?

Answer

An ice-lined refrigerator (ILR) is an appliance that is artificially kept cool using medical-grade ice packs in order to store or transport highly perishable medical supplies such as vaccines, medicines, blood bags, and organs for transplant, without requiring an external power supply for maintaining temperature. An ice lined refrigerator typically maintains a steady internal temperature ranging between 0°C and 8°C with the aid of microprocessor-based temperature sensors and is designed to be highly portable. Most ice-lined refrigerators from reputed manufacturers can maintain requisite temperatures for a period extending to over 24 hours. ILRs come in various sizes – the most common ones being 100 L, 200 L, and 300 L.
