refrigerated trailer (reefer)

(road transportation) An insulated and refrigerated truck trailer designed to transport perishable goods. Commodities transported include vegetables, fruits, milk, juices, meats, poultry, and pharmaceuticals. Shorter trailers are typically used for local deliveries or in tandem “truck trains.” The standard axle/wheel configuration is 2-axle/8-wheel. For heavier loads, 3-axle/12-wheel or 4-axle/16-wheel configurations are available. Refrigerated trailers feature rear swing or roll-up doors, one or two side doors, moveable bulkheads, lift gates, and temperature recording and monitoring systems. Single- or multi-temperature models are available with a wide choice of refrigeration units.
