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.
Solid blocks weighing about 4 – 6 kg with
the approximate dimensions 7” x 7” x 7”
Bigger sizes of Dry ice blocks weighing
more than 10 kg is also being made.
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,
Quick and convenient source of inert gas
for purging fuel tanks etc.
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
Coldry must not be placed in tightly sealed
containers. Sufficient care (ie) vents must
be provided to allow the gas evolved to
