How does it work?

CO2Blast harnesses the innovative potential of Dry ice blasting to revolutionize surface cleaning and preparation. This state-of-the-art technique leverages the kinetic energy, micro-thermal shock, and sublimation of CO2 pellets to efficiently eliminate contaminants, ensuring surfaces remain immaculate without any abrasion or chemical residue.

The science of dry ice blasting

The cleaning action of dry ice blasting is due to three factors:

KINETIC ENERGY: Compressed air propels the dry ice particles up to supersonic speeds. Though light in weight, they puncture the contaminate and chip away at it, thereby opening the surface of the contaminate.

MICRO-THERMAL SHOCK: An immediate and localized cold shock to the contaminate versus a substrate (surface) which cools down much less. This action promotes a contact break between contaminate and substrate.

SUBLIMATION: As the dry ice sublimes (becomes a gas) on impact, it increases up to 700% of its volume from solid to vapour, when it enters the cracks within the contaminate. This gas expansion, breaking up the contaminate from within, is the major factor responsible for the dry ice cleaning effect.
