CRYO BLASTING
Dry ice blast cleaning (also known as CO2 blasting or cryogenic blasting) was developed as a safe, clean alternative to sandblasting, bead blasting, soda blasting, and hand scrubbing. Since its introduction in 1987, dry ice blasting has grown to become a vital part of the cleaning process in a remarkable variety of industries.
Because of the temperature difference between the dry ice particles (-109°Fahrenheit / -78.3°Centigrade) and the surface being treated, thermal shock occurs during the dry ice blasting process. This breaks down the bond between the substrate and the contaminant to be removed from it. The dry ice vaporizes on impact, so no secondary waste stream is created
A number of industries have discovered the advantages of this precision cleaning process. Applications range from heavy slag removal to delicate semiconductor and circuit board cleaning.
