 Dry ice blasting is similar to traditional shot blasting, however the fundamental difference is that the shot is replaced by pellets of dry ice which disappear as soon as the
cleaning cycle is complete.
Dry ice is the solid form of carbon dioxide (CO2) which changes directly from a solid to a gas, leaving no residue. At atmospheric pressure it sublimes at -78.7°C providing a
cooling effect of 628 kJ/kg.

The CSL-2000 has one of the most advanced and environmentally friendly methods of surface cleaning or decontamination. It is ideal for cleaning a wide range of surfaces both hard and
delicate.
By modifying the very straight forward pneumatic dry ice flow control on a CSL-2000, cleaning environment can be changed to ensure removal of only the contaminants from surface coated
components, allowing the bond between substrate and coating to remain intact. On the other hand, the cleaning parameters can be set to the optimum level and both contaminant and coating
can be removed in a single operation.
One of the main benefits of using this technology is how environmentally friendly it is which has no problems associated with the removal of blasting medium the ice sublimes during the process.
Compare to solvent cleaning there are no toxic fumes, and no hazardous liquid waste is created.
