What is Dry Ice
About Dry Ice

Dry ice is the solid form of carbon dioxide (CO2). It's called "dry ice" because it does not melt like wet ice. Instead, dry ice converts into carbon dioxide gas. Because dry ice is extremely cold ( -109°F /-78.5°C), non-toxic, and completely dry, it is commonly used as an expendable refrigerant to ship frozen food or medical products or to cool materials during production.

The other major use of dry ice is for dry ice blast cleaning, an effective and environmentally friendly way to clean industrial equipment.

Dry Ice Uses & Applications

Dry ice is the trademark name for solid carbon dioxide.
To produce dry ice the gaseous carbon dioxide is liquefied through compression and turned into a solid form through expansion. It becomes a white, cryogenic carbon dioxide-snow, which is compressed in hydraulic presses resulting in blocs, slabs and pellets. Dry ice is colourless, odourless and tasteless.

The low temperature and direct sublimation to gas makes dry ice a very effective coolant, since it is colder than ice and leaves no moisture as it changes state.

Dry ice has a cooling capacity of 576 KJ/Kg and 159.4 W/Kg. It is an important refrigerant for keeping foods cold and preventing bacterial-growth during transportation.

Hence, food remains preserved for many days and does not get spoiled during shipment.

  • Is a natural cooling agent
  • Is carbon dioxide (CO2) in solid form
  • Is cryogenic (78,9° C)
  • Is bacteriostatic and suppresses the atmospheric oxygen
  • Has a high refrigerating capacity
