Dry ice blasting involves using recycled CO2 in the form of solid particles (pellets) propelled by compressed air through high velocity nozzles onto the surface to be cleaned. The combination of the kinetic and thermal effects of dry ice destroys the bond between the contaminant and the piece to be cleaned. Upon impact with the contaminant, the dry ice particles sublimate, i.e. convert directly from the solid to a gaseous state, and literally make the contaminant vanish without a trace with no secondary waste from the blasting medium. Essentially, this results in a high-quality blast with no risk of damage to the surface being cleaned. In this cleaning process the contaminant is literally vaporised and removed without leaving any trace.
Dry ice blasting systems use less raw material, energy and air than any other jet processing system available on the market. They only require minimum maintenance and let the customer focus on their main activities rather than waste valuable time on extraneous cleaning activities and expose their staff to the adverse effects of chemicals used in traditional cleaning methods
