Cold room doors are materials that ensure minimum heat transfer from inside and outside during product, food, equipment, and human entry-flow so that the stored products can be stored without deterioration. Doors are manufactured by injecting polyurethane with a density of 40+-2 are between two plate sheets ( polyester, PVC, plastisol, CrNi). It is used in cold and frozen storage rooms and blast freezing rooms. The surfaces are produced with the same coating as the panel surfaces or different surface coating. Door leaf and frame are polyurethane filled, there are thermal bridges. There is an anti-panic handle that can be locked from the outside with a key and can be opened from the inside with or without a key. There is a resistance against freezing in frozen storage and blast freezing doors.
