The refrigerated truck body of Yufeng helps maintain consistent temperature control conditions within the cargo area by reducing passive heat transfer regardless of external conditions. The front and floor are covered with 80mm polyurethane foam, while the sides and ceiling are covered with 80mm insulation, providing significant insulation effects regardless of whether you choose aluminum, Yufeng, or FRP wall structures. Yufeng also offers 10mm and 120mm insulation packaging options to help you overcome particularly challenging conditions.
