A reefer trailer, short for refrigerated trailer, is a type of insulated trailer with a built-in refrigeration unit. It is designed to transport perishable and temperature-sensitive goods, such as fruits, vegetables, dairy products, meats, and flowers, at consistent and safe temperatures. The refrigeration system of a reefer trailer works to remove heat from the trailer, maintaining the temperature of the cargo during transportation. These trailers are essential for cold chain logistics, ensuring the safe transport of perishable products along the supply chain
. Typically, reefer trailers are the same size as an average semi-trailer, about 53 feet long, and are equipped with various components such as the reefer unit, insulated box, air chute, air ride suspension, and tire inflation systems
