Reefer Trailers

Home » Truck & Trailer Solutions » Box Trailers

Reefer trailers (Refrigerated semi-trailers) are responsible for a large amount of cold chain transportation, used to transport agricultural products, frozen foods, meat, flowers, etc. They are favored by logistics companies for their cargo capacity and volume, especially in long-distance transportation. Compared with full trailers, they are more flexible to operate and can be quickly connected and separated, and reversing is more convenient. Usually, two semi-trailers can be towed by one vehicle at the same time, which greatly improves transportation efficiency.

Materials and Components in Reefer Trailers

Unlike dry cargo semi-trailers, reefer trailers need to maintain long-term refrigeration, so high-quality materials and advanced technologies are required to ensure safe and efficient transportation of goods.

Component	Common Materials
Outer Skins	Aluminum, Stainless Steel, FRP, Prainted Steel
Insulation Core	Polyurethane Foam (PU), Extruded Polystyrenee (XPS), Expanded Polystyrene (EPS)
Flooring	Aluminum, FRP, Stainless Steel , Wood, Bamboo
Refrigeration Unit	Compressor, Condenser, Evaporator
Doors and Seals	Rubber, Silicone, Stainless Steel
Interior Linings	Aluminum, FRP
Lighting and Safety	LED Lights, Reflective Tape
Ventilation	Air Ducts, Ventilation Systems
Chassis and Suspension	Steel, Aluminum, Air Suspension

Dimensions (40ft to 53ft)

Reefer trailers are available in a variety of sizes, with 40-foot, 45-foot, 48-foot and 53-foot configurations being the most common in global transport.
