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.
Owing to its extreme low temperature, dry ice is used in a variety of industrial, food and bio-tech industries. This includes temperature sensitive product distribution, fit shrinking of metal parts and bearings, theatrical and movie special effects, camping, hunting and fishing.
Airweld Inc. supplies dry ice pellets in a variety of sizes from one pound to five-hundred pound cold bins.
