Dry ice is the solid form of CO2, which is an odorless and colorless gas under normal conditions and naturally present in the air. It exists as a solid at -78.9°C. Under normal pressure, solid CO2 sublimates directly without undergoing a liquid phase, meaning the jet medium completely disappears, leaving only the original contaminants to be dealt with. Therefore, dry ice is superior to water and other chemical agents in cleaning applications.

Dry Ice Cleaning Decontamination Principle: 

Using extremely low-temperature dry ice pellets, they are喷射towards the object being treated, causing the dirt on the surface to freeze, become brittle, and crack. As the dry ice pellets hit the crevices of the dirt, they immediately sublime, expanding in volume nearly 800 times instantaneously, thereby lifting the dirt away from the surface. The dry ice cleaning process utilizes compressed air as the motive force to propel the dry ice pellets towards the surface of the object, achieving the cleaning goal.

Dry Ice Cleaning Features: 

·Dry cleaning, without water or chemicals, avoids secondary pollution, eco-friendly, and safe and reliable.

·High-pressure jet cleaning, no need to wipe or wear away the object being cleaned, without damaging the object itself, improving its service life.

·Online operation minimizes disassembly and installation, extending the lifespan of the equipment.

Shorter cleaning time, reduced costs, and increased equipment utilization.

·Electrical equipment requires no power shutdown for cleaning, with a voltage resistance of 3.4kV, providing thorough cleaning results and significant economic benefits.
