Product overview

Phu Son manufactures and installs the complete range of cold store doors: sliding doors for cold and freezer stores, and hinged doors for above-zero and deep-freeze stores. The leaf uses a 40 kg/m³ PU foam core matched to the cold store panel system.

Sliding doors have a heating element to stop the frame icing, and work down to -45°C. Hinged doors are used on above-zero stores over 7°C and on deep-freeze stores, are smaller, and have no heating element.
