Refrigerator truck
Encyclopedia
A refrigerator truck is a van
or truck
designed to carry perishable freight at specific temperatures. Like refrigerator car
s, 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.
Most of the long-distance refrigerated transport by truck is done in articulated trucks
pulling refrigerated semi-trailer
