This cleaning method utilizes solid carbon dioxide pellets propelled at high velocity to lift dirt and contaminants from surfaces. The process combines the impact of the pellets with a thermal shock that causes the unwanted material to become brittle and easily detach. An example would be restoring fire-damaged equipment without creating secondary waste streams from water or abrasive media.
Non-abrasive, environmentally responsible, and requiring minimal downtime, this technology offers significant advantages over traditional cleaning methods like sandblasting or solvent washing. It eliminates the need for chemical cleaning agents and reduces water usage, contributing to a greener footprint. Originally developed for industrial applications, its versatility has expanded its use across various sectors, including historic preservation and food processing.
