Dry Ice blasting is also known as, CO2 blasting, or cleaning with Dry Ice. Dry Ice is the solid form of carbon dioxide.
The Dry Ice is accelerated in a pressurised air stream, and expelled through a hose and nozzle. When pointed at the surface, the dirt is cleaned off, without damaging the sub-straight. It is non abrasive. It is similar to soda, and sand blasting but as it uses dry ice as the blasting medium.
Dry Ice is non toxic, non abrasive, non conductive and non flammable. Compared to other media blasting methods, cleaning with dry ice does not create secondary waste or chemical residues as dry ice converts back to a gaseous state, when it hits the surface that is being cleaned. Dislodged dirt can just be swept up, vacuumed or washed away.
Cleaning with Dry Ice is an efficient cleaning method, & is quickly becoming the favoured method of cleaning in a large number of industries where the use of abrasives, water or chemicals is not possible or creates other challenges.
Dry ice is made of reclaimed carbon dioxide that is produced from other industrial processes, and is an approved media by the EPA, FDA and USDA. It also reduces or eliminates employee exposure to the use of chemical cleaning agents.
The environmental benefits include cleaning with a natural substance, replacing chemicals and minimising the need for special waste disposal.
