General Information about Dry Ice

What is dry ice?

Dry ice is the name for solid CO2. At atmospheric pressure it has a temperature of approx. -79° C (-110,2 °F). The evaporisation is residue free. Dry ice is non toxic, non flammable, inert, tasteless and odourless. It is white and has a density of approx. 1'500 kg/m3 (93,64 lb/ft3)in its compact form.

Applications of dry ice

Dry ice is an ideal cooling media which can be used for many applications. It has a high cooling capacity. Dry ice blocks/slices or dry ice pellets are used for cooling purposes.

ASCOJET Dry Ice Blasting is a powerful, gentle, dry and ecologically friendly cleaning method causing no secondary waste. It is applied in many industries. For the cleaning of surfaces with our ASCOJET dry ice blasting technology dry ice pellets with the diameter of 3 mm (0,12 in) are standardly used. Dry ice pellets with a diameter of 1.7 mm (0,06 in) can also be used for the cleaning of delicate surfaces. For cooling purposes dry ice blocks and pellets with a bigger diameter are used.

How dry ice is produced

Dry ice is produced from liquid carbon dioxide (CO2). Inside a dry ice pelletizer, the liquid carbon dioxide is expanded under controlled conditions to form dry ice snow. This snow is then pressed through an extruder plate into round, hard pellets (elongated grains with a diameter of 3 mm or 1.7 mm according to the used extruder plate) for dry ice blasting purposes or into larger pellets/dry ice slices/blocks for cooling purposes.  

Dry ice for cooling purposes

Dry ice is an ideal cooling media which can be used for many applications. It has a high cooling capacity. Dry ice blocks/slices or dry ice pellets are used for cooling purposes.


In-house dry ice production

In-house dry ice production starts paying at a need of several hundred kilograms dry ice per week. ASCO is in a position of providing interesting all-in-all CO2 concepts, these can be realised without making any major investments. 

 

Advantages of an in-house dry ice production:

  • Less dry ice loss due to sublimation
  • More flexibility as you always have freshly produced dry ice at your disposal
  • Better and faster cleaning results because the fresher the dry ice, the more effective the cleaning
  • Less dry ice used
  • Shorter production standstills
  • Less time and money spent on buying and transporting
