DRY ICE BLAST CLEANING - Technology

Four Stages of dry ice blasting

1.
Tiny dry ice pellets at -79 °Celsius are propelled from a compact, self contained unit at supersonic speed through a dry ice cleaning gun using specially treated compressed air.
   
2.
The dry ice pellets hit the surface (to be removed or cleaned) creating a thermal shock wave.
   
3.
Upon impact they sublimate into gas breaking the surface-substrate bond.
   
4.
The resulting tension dislodges the surface material without damaging the substrate while the harmless CO2 gas from the sublimated dry ice is absorbed back into the atmosphere. There is no water, sand, grit, chemicals, solvents or other toxic secondary contaminants to discard with this eco-friendly technology.
