A technologically advanced, environmentally responsible surface preparation and cleaning method for all industries, dry ice blasting, the CryoGenesis cleaning process utilizes dry ice (Solid CO2) which is formed into 3mm rice like pellets (Drice®) or blocks of dry ice which are ground into tiny particles the size of sugar crystals. These particles are then accelerated to supersonic speeds via a blasting unit and applied using a hand held or robotized blasting gun to the surface to be cleaned. Upon impact, the dry ice immediately turns from its solid state into carbon dioxide vapour expanding up to 540 times its volume. The energy produced by the conversion of solid to vapour is considerable and is responsible for much of the cleaning process. The vapour disappears back into the atmosphere, leaving only the removed contaminant itself for disposal. Unlike conventional blast cleaning methods: grit, sand, plastic media etc. Dry Ice blast cleaning is non-abrasive to the impacted surface.
