What is dry ice cleaning?
Dry ice cleaning, also called cryogenic cleaning, involves projecting solid carbon dioxide pellets (-78.5ºC) onto a surface. Upon impact, the dry ice sublimates and causes a thermal shock that removes dirt without the need for water, solvents, or abrasives.
Main features
- Dry process: does not generate humidity or corrosion.
- Non-abrasive: respects the integrity of surfaces, even the most delicate.
- Ecological: recycled CO2 and absence of secondary chemical products.
- Safe: non-toxic, non-flammable, and suitable for live electrical equipment.
Advantages for duct cleaning
- Removes embedded dust and grease without disassembling the ducts.
- Reduces the risk of legionella and improves indoor air quality.
- Minimizes downtime in industrial air conditioning and HVAC.
- Complies with cleaning and occupational health regulations.
Measurable results
After dry ice cleaning, ventilation systems recover their thermal and energy performance by up to 15% in some cases, reducing electricity consumption and prolonging the lifespan of components.
Other industrial uses
- Demolding in the plastic and rubber industry.
- Degreasing of machinery and engines.
- Removal of paint and coatings in maintenance.
- Restoration of surfaces after fires (soot and smoke).
Frequently Asked Questions
Does dry ice scratch the ducts?
No, the process is non-abrasive and keeps the metal or polymer intact.
Do I need to stop production?
In most cases, no, thanks to in situ cleaning without disassembly.
What happens to the CO2 used?
It sublimates into gas and disperses; it leaves no solid or liquid residues.
