Refrigerated trucks are enclosed box-type transport vehicles used to maintain the temperature of frozen or preserved goods. They are specialized transport cars equipped with refrigeration units and polyurethane insulated bodies. Refrigerated trucks can be categorized by the manufacturer, chassis carrying capacity, and body style.

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

　　Refrigerated Trailer Manufacturing Technology:

1. Sandwich panel assembly with adhesive bonding, this technology is widely used by major domestic refrigerated truck manufacturers. Trucks produced with this technique offer superior thermal insulation performance.

2. Modular assembled injection foam.

3. Overall frame injection foam style.

4. Vacuum吸附tape

Refrigeration Unit Categories:

Refrigeration units are categorized into non-independent and independent cooling systems, 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 (functioning as an evaporator) can be installed in the container.
