Using pressure blasted particles of solid carbon dioxide (commonly called dry ice), instead of using small, abrasive particles for blasting, dry ice blasting uses a pressurized stream of dry ice pellets that are initially solid and begin to sublimate (instantaneously turn to gas) upon impact. Surface coatings like paint oil, adhesives, and accumulated debris shrink from the change in temperatures and are forcibly blown off the surfaces they are attached to, leaving a clean, dry substrate. Eliminating the need for water and reducing hazardous waste or chemical drainage, cleanup following dry ice blasting is as easy as sweeping up the residue that has been removed from the surfaces. This is especially effective in environments where pollution and dust are detrimental to the system’s operation.
The pressurized stream of dry ice pellets is able to clean in nooks and crannies of all sizes, without the equipment having to be taken out of service or disassembled. Because it is also non-conductive, electrical parts and other equipment do not have to be powered down nor do you have to wait for the operating temperature to lower. Since there is no water introduced during this cleaning process, electrical parts and other equipment can be back in service immediately because you don’t have to wait for water or chemicals to dry.
