DRY ICE USES
DRY ICE

Dry ice is the solid form of carbon dioxide (CO2)
with a temperature at -109.3°F (-78.5°C) or below. Dry ice is
especially useful for freezing and keeping things frozen because
of its very cold temperature. At normal atmospheric pressure,
dry ice sublimates directly into carbon dioxide gas without
going through a liquid stage.
Specification
Temperature: -78.50C (-1730F)
Free of Water, Non Conductive, Anti Bacterial, Non Toxic
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
- Dry Ice must not be placed in tightly sealed containers. Sufficient care (ie) vents must be provided to allow the gas evolved to escape.
