Insulated cold storage panels are made with a lightweight polyurethane core material, with a sandwich panel structure on the outside consisting of SII, PVC coated steel, and stainless steel plates. This design reduces heat transfer due to temperature differences between the inside and outside, achieving maximum efficiency in refrigeration and freezing systems. The cold storage panels have strong resistance to deformation and cracking, with a stable and safe finish. The quality of the cold storage panels directly affects the lifespan of the cold storage, making the quality of the panels a crucial factor in selection.
