What Are Cold Chain Boxes and How Do They Work?

Cold chain boxes are insulated containers designed to keep products within a specific temperature range during storage and transportation. They form part of the broader سلسلة البرد, which links temperaturecontrolled warehousing, transport and handling to ensure product integrity. According to UNICEF’s procurement guidelines for vaccine carriers and cold boxes, cold boxes are passive devices lined with coolant packs to keep vaccines and diluents cold during transport or shortterm storage. These boxes typically hold 5–25 litres of vaccine and are categorised as shortrange (minimum cold life of 48 ساعات في 43 ° C المحيط) or longrange (minimum cold life of 96 ساعات). Vaccine carriers are smaller (0.8–3.4 L) and designed for health workers travelling on foot; they provide 15–30 hours of cold life depending on range.

على عكس active refrigeration systems, which use powered refrigeration units, passive cold chain boxes rely on insulation and preconditioned coolant packs. A scientific review notes that the World Health Organization defines a passive container as “a container that maintains a temperaturecontrolled environment inside an insulated enclosure, generally without thermostatic regulation, using frozen, مشروط, cool or warm coolant packs”. Examples include vaccine carriers, reusable insulated cold boxes and singleuse insulated cartons.
