A refrigerated warehouse (also called cold storage) is a temperature-controlled facility used to store perishable goods such as food, pharmaceuticals, and chemicals. It maintains specific temperature ranges to preserve product quality and prevent spoilage. These warehouses use insulated panels, refrigeration systems, and humidity controls to maintain consistent conditions. The four main types of warehouses are: The cost varies depending on size, location, insulation, and refrigeration systems. For a 50,000 sq ft refrigerated facility, costs can range from £10 million to £20+ million, depending on specifications. Major cost factors: A reefer warehouse is simply another term for a refrigerated warehouse. The term “reefer” comes from refrigerated containers (reefers) commonly used in shipping and logistics. Temperature depends on what’s being stored: Examples include: There’s no universal legal minimum temperature, but: Work rotation and warming breaks are commonly required in extreme cold environments.
