Dry ice blasting utilizes frozen carbon dioxide pellets (-78C) propelled at high speed to remove surface contaminants without leaving any secondary residue.
It is particularly useful for cleaning within commercial facilities with minimal disruption to manufacturing or production. The process is similar to sandblasting and other forms of media blasting but instead of using hard abrasive media, it uses soft dry ice to lift the undesirable surface elements without damaging the underlying substrate. It is similar to water pressure washing without the mess. Ice pellets sublimate as they strike the surface thereby eliminating the need to clean up media such as sand blasting following the procedure.
Dry ice cleaning is environmentally safe. Carbon dioxide is a natural by-product of several industrial manufacturing processed such as fermentation and petrochemical refining. It is captured and stored until it is needed to manufacture dry ice. When it is released during the blasting process, no new carbon dioxide is produced, only the original material is released.
