DRY ICE

Coldry is SICGIL's trademark for solid carbon dioxide, commonly known as dry ice. Compared to normal ice, dry ice changes directly from a solid to a gas when it absorbs heat. Dry ice with the temperature of MINUS 78.4 º C, absorbs 573 kJ of heat per kg compared to 335 kJ per kg for water ice.

Products

Solid blocks weighing about 4 \96 6 kg with the approximate dimensions 7\94 x 7\94 x 7\94
Bigger sizes of Dry ice blocks weighing more than 10 kg is also being made.

Applications

In-transit refrigeration of foods, ice cream, pharmaceuticals and other temperature-sensitive materials (like vaccines)
Process cooling during chopping/blending/mixing/mincing/grinding operations of meat.
Dry ice blasting cleaning system for moulds, machinery, buildings etc.etc.
Shrink fitting metal components for an interference fit e.g. axles into gear wheels
Production of fog effects for theatres, discos etc.
Quick and convenient source of inert gas for purging fuel tanks etc.
Freeze-branding livestock

Safety

Intensely very cold and hence contact with bare skin should be avoided
Carbon dioxide gas is heavier than air and is an ashyxiant - care should be taken to avoid accumulation at low levels or in confined spaces
Coldry must not be placed in tightly sealed containers. Sufficient care (ie) vents must be provided to allow the gas evolved to escape.
