Articulated lorry with refrigerated trailer

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. Sometimes they are used to carry dead human beings.

The first successful mechanically refrigerated trucks were made for the ice cream industry in 1925.[1] African American inventor Frederick McKinley Jones later contributed to the field. 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]

About 1925, the ice cream industry pioneered the first successful mechanically operated refrigerated trucks, which were operated by methyl chloride condensing units. A generator, driven by a gasoline engine, supplied the power for the compressor motor.
