The CO2 SnoGun cleaning process is based on the expansion of gaseous carbon dioxide through an orifice. This expansion leads to the creation of small dry ice particles propelled by a high velocity gas stream that is sprayed onto the parts by the CO2 SnoGun. Upon impact with a dirty surface the dry ice media removes the unwanted particles. When using the CO2 SnoGun, even submicron particulates and hydrocarbons are removed by this transient solvent or freeze fracture mechanism. |
