How it works
Cryonic's dry ice cleaning is a blasting technique similar to sand blasting, but makes use of solid CO2 or dry ice pellets. It captures what would have been a waste product (carbon dioxide), and converts it into a usable product, solid 3 mm carbon dioxide 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.
The advantage of using dry ice pellets as blasting material is twofold: the very low temperature of the dry ice pellets (-78 °C) causes the contaminant to freeze and contract resulting in the easy detachment of the contaminant from the substrate.
The process also overcomes environmental issues as no water is used and it also helps to eliminate waste as the surface contaminate is captured and disposed of in the correct manner.
Applications
The technology is suitable for a range of industries, including automotive, food processing and construction. This process is said to provide significant productivity and safety benefits in the manufacturing processing sector. The key advantage of using dry ice as a cleaning method is that it allows items to be cleaned in situ.
