The basic specification for Snowman cold storage is to maintain the air temperature for storage at -20 Deg C in order to retain the temperature of product stored at -18 Deg C which is international standard for frozen food. Since there could be variation in the temperature of incoming products and to provide better safeties the cold storage or in other words freezer storage have been designed for operation at -25 Deg C with flexibility of incoming materials up to -15 Deg C.

The cold store comprises of insulated sandwich panels made of polyurethane lined with metal skins on both the sides having density of 37 kg/m3 sq. with thickness of 150 mm. The panels are made from CFC free polyurethane materials. The panels are supported with steel structural framework acting as building. The structure is properly covered with steel sheeting to protect from rain and wind.

The air temperature is reduced by using refrigeration system using two stage reciprocating compressors with suitable air handling units and evaporated condensers with proper control system. The refrigeration system operates on CFC free R404a gas manufactured by Dupont USA .

The material storage arrangement is on standard two deep racking system which can store materials on Euro pallets of size 1000 X 1200 X 1500 mm with vertically 4 high arrangements. The pallet movement is with the help of battery operate electric forklift reach truck suitable for lifting the material from 4th level and second depth of the rack.

The loading and unloading of the materials from or into the refrigerated truck is done with the help of suitable dock levelers and dock shelters. The dock shelters are air locking the trucks into the cold storage area while the leveler matches the floor level of the truck with that of the cold storage.
