A Refrigerator truck is a closed box-type transport vehicle used for transporting frozen or fresh-keeping goods. It is a refrigerated special transport vehicle equipped with a refrigeration unit, a refrigeration device and a polyurethane insulated compartment. It is often used to transport frozen food (freezer truck) Dairy products (dairy transport vehicles), vegetables and fruits (fresh goods transport vehicles), vaccines and medicines (vaccine transport vehicles), etc.

Refrigerated trucks are composed of the traveling part of a dedicated vehicle chassis, an insulated and heat-preserving body (generally made of polyurethane materials, fiberglass reinforced plastic, color steel plates, stainless steel, etc.), a refrigeration unit, a temperature recorder inside the refrigerated truck, and other components. For vehicles with special requirements, such as meat hook trucks, optional accessories such as meat hooks, waist frames, aluminum alloy guide rails, and ventilation slots can be added.

Only by using and operating the refrigerated truck correctly can the goods be transported and preserved in good condition. Since refrigerated trucks are specifically designed for temperature-sensitive products, ensuring temperature is the key to refrigerated trucks. If used or operated improperly, it will result in the goods not being stored or transported in good condition.
