The Ice Blaster 15/80 is an innovative blasting system which uses dry-ice pellets (compressed CO 2 snow) as an abrasive. Setting new standards in surface cleaning, the dry ice blasting process is very similar to that of sand blasting. In principle, the pellets are injected into a jet of compressed air, accelerated to speed in excess of 150m/s and fired at the surface. Dry ice pellets impact the contaminated surface, causing the dirt to go brittle and fall from the surface. At this point the pellets change from a solid to a gaseous state and blast away the dirt without leaving any residue.
