It sublimates and returns to the atmosphere as carbon dioxide (CO2 ) gas. CO2 is a naturally occurring element that constitutes less than 1% of our atmosphere.

The dry ice blasting process will not damage the substrate. The size and velocity of the dry ice pellets can be changed to remove the contaminate while being nonabrasive to the substrate.

The process cleans best hot. Most contaminants have weaker adhesive strength when hot. In many applications, you may be able to clean three to five times faster hot than cold. In addition, because dry ice sublimates on impact, entrapment of the blasting media is not an issue. Grit entrapment is the reason those who clean with sand, walnut shells, or other grit media cannot clean online.

In the two-hose system, the dry ice travels in one hose and the high-pressure air in another. The two are not mixed until just before the pellets exit the end of the nozzle. In a one-hose system, the pellets and air are mixed together in one hose.

Yes. Any dry air process will generate static electricity and dry ice blasting is no exception. All equipment used by A&H Dry Ice is designed with grounding devices. As long as both the blasting unit and the piece you are blasting are properly grounded, you are unlikely to have any static discharge problems.
