4x2 Sinotruk Howo Small Frozen Truck 4-5tons

A refrigerated truck is a closed box type transport vehicle used to transport frozen or fresh goods. This specialized vehicle combines a dedicated chassis with an insulated compartment, refrigeration unit, and temperature monitoring equipment. Common applications include frozen food, dairy products, vegetables, fruits, vaccines, and pharmaceuticals. The refrigerated body employs insulation materials such as polyurethane, fiberglass, color steel plate, or stainless steel. Optional accessories for specialized needs include meat hooks, waist guards, aluminum guide rails, and ventilation ducts. Manufacturing approaches vary: sandwich-panel adhesive assembly (most common for large manufacturers), injection foam sectional assembly, overall skeleton foam injection, and vacuum adsorption adhesive methods. Refrigeration units come in independent and non-independent types. Independent units rely on separate power generation, while non-independent units draw power from the vehicle engine. Selection depends on compartment volume and temperature requirements for transported cargo.
