Cold Storages usually maintain 0° C for Potatoes, 5 o C for Fruits & -4° C to -20° C for Vegetables and Dairy Products . Cold Storages are in need of good quality Insulation as they constantly need to maintain a fixed temperature 24 x 7 keeping in mind that they store Food Items and Vegetab les. The insulation plays a very important role in this. Right from floor to ceiling Insulation is required. The pipes running throughout the cold storage need to be covered in Insulation. Apart from this even the Refrigerant and Ammonia Tanks and Pipes in the Machine Room have to be covered in Insulation Material. Major Insulation for Cold Storages are Elastomeric Nitrile Rubber and Extruded Polystyrene.
