Dry ice – information
Dry ice is the solid form of carbon dioxide (CO2). Pellets, nuggets, slices and blocks of dry ice are produced in specialised equipment. The carbon dioxide expands first and subsequently soft powder is formed – snow CO2. This snow is forced through a special mould where it is pressed and densified and dry ice in the form of pellets or nuggets is created. The technology used to create blocks is slightly different.
Dry ice physical properties:
Temperature: – 78,8 ºC
Heat of sublimation: 640 kJ / kg (from -78 ºC to 0 ºC )
Density: 1,2 – 1,6 kg / dm3
Sublimates into gaseous CO2, 1 kg of dry ice = 541 litres of CO2
Odourless and flavourless
Limit in the air: 0.5 % of volume
Loss of consciousness: > 8 % of volume
Dry ice use
Cooling during transport
CAUTION! When handling dry ice health and safety instructions must be followed syfety instructions!
