Refrigerated Trailer
Refrigerated trailers are a type of special vehicle specifically designed for transporting goods that need to be stored at low temperatures. Their outer layers are generally made of high-strength and corrosion-resistant metal materials, such as fiberglass reinforced plastic or aluminum alloy. FRP (Fiber Reinforced Plastic) has the advantages of light weight, high strength and corrosion resistance, and can effectively protect the internal structure of the box. Aluminum alloy has good thermal conductivity and lightweight characteristics, and at the same time, it has an attractive appearance.
The middle layer is an insulating and heat-preserving layer, which usually uses highly efficient insulating materials such as polyurethane foam. Polyurethane foam has excellent heat insulation performance, which can effectively prevent external heat from entering the cabin and maintain a stable temperature inside the cabin. Its thickness varies according to different insulation requirements, generally ranging from 80 to 150 millimeters.
The inner layer is mostly made of stainless steel or food-grade plastic plates. These materials have good hygiene performance, are easy to clean and disinfect, and meet the strict requirements of the food, pharmaceutical and other industries for the transportation environment.
