What is Dry Ice

What is Dry Ice?

phase changes in carbon dioxideDry Ice is the solid form of carbon dioxide. It is used primarily as a cooling agent. Its advantages include lower temperature than that of water ice and not leaving any residue (other than incidental frost from moisture in the atmosphere). It is useful for preserving frozen foods, ice cream, etc., where mechanical cooling is unavailable.

Dry ice sublimates at −78.5 °C (−109.3 °F) at atmospheric pressure. This extreme cold makes the solid dangerous to handle without protection due to burns caused by freezing (frostbite). While generally nontoxic, the out gassing from it can cause asphyxiation due to displacement of oxygen in confined locations.

Buzwair Dry Ice Services offers high quality Dry Ice products to support a variety of industries and our own cleaning services. The products we are able to offer are: 3mm, 10mm, 16mm and 102mm x 102mm x 25mm slices as well as storage containers for shipping and transportation.

Properties of Dry Ice

  • Dry Ice temperature is -78.5 degree celcius (-173 F)
  • Specific weight is approx 1450 kg/m3
  • Dry ice is free of water (pure CO2 = 100% dry)
  • Dry ice is not conductive
  • Dry ice converts to CO2 vapor on surface impact
  • Dry ice is free of oxygen (anti bacteria)
  • Dry ice is not toxic (food grade)


  • No disassembly and re-assembly of equipment
  • Non-abrasive, therefore, no surface stresses are created and no change in cavity size or round corners through wear
  • No special preparation is required, e.g. masking, covering
  • Plastic, glass, rubber, steel, and concrete can all be cleaned
  • Electrical components and areas around bearings can be cleaned
  • Helps equipment run more efficient
  • Improves maintenance efforts
  • Production equipment normally dismantled and transported to a special area can be cleaned safely in place on the production floor, thereby saving substantial downtime and other resources


  • Provides quicker and superior clean
  • Provides a perfectly clean, dry and prepared surface for recoating
  • No moisture
  • Doesn't burn our fixtures or damage electrical equipment
  • Aggressive enough to clean tough surfaces and sensitive enough to clean delicate equipment, e.g. industrial control panels, manfans, and other electrically sensitive equipment
  • Cleans nooks and crannies and other areas that are almost impossible to manually clean
  • No messy clean-up, collection, or disposal problems
  • Stop growth of mold, mildew, bacteria, and other fungi as well as stop odors at the source by elimination of the bacterial host environment ( not like a masking agent and cover-up )


  • Non-Toxic
  • Non-Conductive
  • No harmful emissions
  • Safe for employees
  • Safe for end products
  • Safe for the environment
  • Safe for equipment
  • Carbon Dioxide is safer than toxic or environmentally harmful chemicals
  • No hazardous chemicals eliminates employees exposure and corporate liability
