How does dry ice cleaning work?

Dry ice cleaning uses small particles of dry ice (with the size of a grain of rice) as a cleaning agent. Dry ice particles will not generate any secondary waste from the cleaning agent.

This cleaning technology is applied in various sectors, from fire restoration and mold elimination, from food processing to electrical and nuclear applications.

The peculiarity of dry ice is to remove the contaminant, then it cleans the product, without modifying its surface.

Dry ice works by means of three physical principles:

❄︎ Kinetic energy derived from compressed air which is the vehicle that transports the dry ice and therefore acquires a certain energy with speed

❄︎ Thermal shock resulting from dry ice temperature, that is-78.5 ° C, that cools and embraces the contaminant

❄︎ The sublimation when dry ice impacts with kinetic energy, it “changes state”, or sublimates, that is, dry ice passes to the gaseous state (in this passage the gas that develops from the transformation of the dry ice state increases by 750 times, then causes micro explosions)

Thanks to these three factors, kinetic energy, thermal shock and violent sublimation (micro explosions), cleaning and removal of contaminants from the substrates to be treated is achieved.
