Dry Ice Cleaning Machine Working Principle
A dry ice blasting machine uses compressed air as its power source to accelerate dry ice particles at supersonic speeds toward the surface being cleaned. Unlike methods that rely only on kinetic impact, this process also uses the ultra-low temperature of dry ice for enhanced cleaning power.
When dry ice particles strike the surface, they instantly sublimate on impact. This rapid sublimation creates swift heat exchange, causing dry ice, or solid CO₂, to turn into gas and expand nearly 800 times its original volume. The resulting micro-explosion effect helps lift contaminants from the surface for a deep and thorough clean.
Compressed Air Drive
Compressed air accelerates dry ice particles toward the surface for targeted cleaning impact.
Thermal Shock
The ultra-low temperature of dry ice helps loosen dirt, oil, carbon, and other surface contaminants.
Residue-Free Cleaning
Dry ice sublimates into gas, helping reduce secondary waste compared with many traditional cleaning methods.
AUTOOL HTS705 Dry Ice Cleaning Machine
Best For
Small workshops and mobile cleaning startups.
Recommendation
