CRYONOMIC Australia says its dry ice cleaning technology can help reduce the use of excessive chemicals in industrial cleaning.
According to Cryonomic Australia, excessive chemical usage can contribute to poor air quality, allergies and poor health.
Dry ice cleaning is a blasting technique similar to sand blasting, but makes use of 3mm solid carbon dioxide (dry ice) pellets. On impact, the pellets vaporise to carbon dioxide gas and increase in volume by a factor of 700. Due to this expansion the contaminant is lifted and separated from the base material.
Cryonomic Australia claims dry ice cleaning has numerous advantages over traditional cleaning methods such as grit or water blasting.
In grit blasting, the blast media quickly becomes contaminated and also acts as a source of environmental pollution. In dry ice cleaning, the blast media dissipates on contact with the surface, leaving no residue.
Additionally, as the dry ice pellets are frozen at -78°C, the contaminant also freezes, allowing easier detachment of the contaminant from the surface being cleaned.
Cryonomic Australia says the dry ice cleaning process does not use water. Due to the lack of waste material after the cleaning operation, the company claims dry ice cleaning can be used in-situ, without having to remove equipment or parts prior to cleaning, reducing downtime.
Dry ice cleaning can be used where water, sand or other cleaning products are not allowed. It may be used on electrical machines and in the food industry.
