The Process The ProcessCryogenic blasting is a technology in which particles of solid carbon dioxide (dry ice) are propelled in a high velocity air stream to impact and clean..., as opposed to the chiseling, abrasive effects of grit blasting. As the dry ice pellets impact the surface, they instantaneously sublimate and return to the atmosphere... in their original gaseous state, leaving no residual blast media, thus eliminating grit entrapment and additions to the waste stream.Additionally, with proper conditioning of supply air...
