DRY ICE BLASTING
Dry Ice Blasting (also known as Dry Ice Cleaning, CO2 Blasting, Dry Ice Dusting, and Environmentally Sustainable Cleaning) is similar to sandblasting, soda blasting and plastic bead blasting – where particles are accelerated in a pressurized air stream to impact the surface to be cleaned or repaired. What sets it apart is that dry ice (CO)2 blasting uses soft dry ice pellets accelerated at supersonic speeds which creates mini-explosions on the surface to lift the unwanted item.
ADVANTAGES OF USING DRY ICE BLASTING:
• It’s colorless, odorless, incombustible, non-abrasive, and non-conductive.
• It contains no secondary contaminants.
• It’s a cleaning process that is approved for use in the food industry.
• Items can be cleaned where they are located without disassembly
• Can be used without effecting active electrical and mechanical parts.
• Can remove biofilms, release agents, contaminants, paints, oils, and chemical residue.
• Can be as gentle as cleaning dust inside an electrical panel or as destructive as removing weld slag
HOW IT WORKS:
Dry ice blasting compresses air to accelerate frozen dry ice pellets to a high velocity. A compressed air supply of 80 PSI/50 scfm can be used in this process. CO2 blasting works because of three primary factors: the pellet’s kinetic energy, thermal shock effect and thermal-kinetic effect.
Dry ice pellets can be made on-site or supplied on demand. These pellets are made from food-grade carbon dioxide which is approved by the FDA, EPA, and USDA.
