Refrigerator truck

A refrigerator truck or chiller lorry is a van or truck designed to carry perishable freight at low temperatures. Most long-distance refrigerated transport by truck is done in articulated trucks pulling refrigerated semi-trailers.

The first successful mechanically refrigerated trucks were introduced by the ice cream industry in about 1925.[1] There were around 4 million refrigerated road vehicles in use in 2010 worldwide.[2]


Like refrigerator cars, refrigerated trucks differ from simple insulated and ventilated vans (commonly used for transporting fruit), neither of which are fitted with cooling apparatus.

Refrigerator trucks can be ice-cooled, equipped with any one of a variety of mechanical refrigeration systems powered by small displacement diesel engines, or utilize carbon dioxide (either as dry ice or in liquid form) as a cooling agent. They are often equipped with small "vent doors" at the rear and front of the trailer. The purpose of these doors is to be kept open while hauling non-refrigerated cargo (often "backhaul"), so as to air out the trailer.[3]
