CO2 Cleaning
Dry ice blasting technology provides residue-free cleaning without secondary waste.
Surface Preparation Technology
Dry Ice Blasting Overview
Dry ice blasting works through the combined effect of high pressure, extreme cold shock, and instantaneous sublimation (transition from solid to gaseous state). This causes dirt to become brittle, detach from the surface, and be blasted away by the rapid expansion of the CO2, leaving no residue as the dry ice simply evaporates.
The robot-assisted cleaning process ensures consistently high cleaning quality, eliminates operator-dependent variations, and delivers reliable, reproducible results. These systems can be easily integrated into existing facilities.
Why CO2 Cleaning?
Advantages:
CO2 cleaning delivers outstanding results with minimal environmental impact and low operating costs.
- —Removes oils, greases, release agents, and particles
- —No chemical waste or post-cleaning required
- —Environmentally friendly and non-abrasive process
- —Component cleaning prior to surface painting
- —Cleaning of electronic components
- —Mold and tooling cleaning
FAQ
Frequently Asked Questions
How does CO2 dry ice cleaning work?
CO2 cleaning propels dry ice pellets at high velocity onto the surface. On impact, the extreme cold (-78.5°C) causes contaminants to become brittle and crack. The dry ice sublimates instantly into gas, leaving no residue, water, or chemical waste behind.
Is CO2 cleaning safe for sensitive surfaces?
Yes, CO2 cleaning is non-abrasive and does not damage the substrate. It is widely used on electronics, composite materials, and precision-machined parts where traditional cleaning methods could cause surface damage.
What contaminants can CO2 cleaning remove?
CO2 cleaning effectively removes oils, greases, release agents, adhesives, paint residues, flux, silicone, and particulate contamination. It is particularly effective for pre-paint cleaning and mold cleaning applications.
