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 temperatures as low as -78.9°C. Under normal atmospheric pressure, solid CO2 sublimates directly without undergoing a liquid phase, which means the jet medium is completely eliminated, leaving only the original dirt to be treated. Therefore, in terms of cleaning, dry ice is superior to water and other chemical agents.

Dry Ice Cleaning Decontamination Principle: 

Using ultra-low-temperature dry ice pellets, they are喷射towards the item to be treated, causing the dirt on the surface to freeze, become brittle, and crack. Once the dry ice pellets hit the gaps in the dirt, they immediately sublime, expanding in volume by nearly 800 times, thereby removing the dirt from the item's surface. The dry ice cleaning process utilizes compressed air as power to propel the dry ice pellets towards the item's surface, achieving the cleaning objective.

Dry Ice Cleaning Features: 

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

·High-pressure jet cleaning, no need for wiping and abrasion, preserves the item being cleaned, extending its lifespan.

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

·Short cleaning time, reduces costs, and improves equipment utilization.

·Electrical equipment can be cleaned without power interruption, with a voltage resistance of 3.4kV, offering thorough cleaning results and significant economic benefits.
