A refrigerated truck is a sealed box-type transport vehicle used to maintain the temperature of frozen or fresh goods. It is a specialized refrigeration vehicle equipped with a refrigeration unit and a polyurethane insulated body. Refrigerated trucks can be categorized by manufacturer, chassis load capacity, and body style.

Refrigerated trucks are commonly used for transporting frozen foods (frozen food transport), dairy products (dairy transport), fresh produce (fresh goods transport), vaccines and pharmaceuticals (vaccine transport).

　　Refrigerated Trailer Manufacturing Technology:

1. "Sandwich" panel adhesive assembly; this technology is widely adopted by major domestic refrigerated truck manufacturers, resulting in refrigerated trucks with superior thermal insulation performance.

2. Segmented assembly for injection foaming.

3. Overall skeleton injection foaming.

4. Vacuum吸附式粘贴

Refrigeration Unit Categories:

Refrigeration units are divided into non-independent cooling units and independent cooling units, including domestic and imported units. Most vehicle types use external refrigeration units, while a few micro refrigerated trucks use internal units. For refrigerated trucks with lower temperature requirements, an internal cooling plate within the van body can be used (which functions like an evaporator).
