Dry ice blasting is a safe and effective way to clean machinery and surfaces. By propelling dry ice pellets at high speeds, Dry Ice International provides dry ice blasting that is highly effective and less abrasive than sand blasting. Sand blasting is an abrasive, surface preparation process, whereas dry ice blasting is a cleaning process that does not alter the surface being cleaned.

What is dry ice blasting

Dry ice blasting is a dry-cleaning method, therefore, even delicate parts such as switchboards and other electric components can be cleaned gently. There is no moisture and no residual media left behind. Dry ice pellets sublimate immediately after impact on the surface, therefore, the time and costs associated with disposal of blasting media are eliminated.

Unlike other blasting media, CO2/dry ice particles have a low temperature of -78.5 °C. Because of the temperature differential between the dry ice particles and the surface being treated, a phenomenon known as ‘fracking’ or thermal shock can occur. As a material’s temperature decreases, the material becomes embrittled, enabling the particle impact to break-up the coating.

Because dry ice blasting is virtually non-abrasive, it is an ideal solution to clean busbars and other equipment where surface finishes should not be altered. This means that in comparison to traditional blasting methods with sand or glass beads, the cleaned surfaces are not damaged or altered.

Dry ice blasting is ecologically friendly. No residual blasting media needs to be disposed of and no solvents or chemicals are used. Dry Ice International offer a comprehensive product range of dry ice cleaning solutions.
