Equipment employing pressurized carbon dioxide, either in liquid or solid (dry ice) form, offers a sustainable alternative to traditional cleaning methods. These systems effectively remove contaminants from various surfaces through different mechanisms depending on the state of the CO2. Liquid CO2 acts as a solvent, dissolving grease, oils, and other residues. Dry ice blasting, on the other hand, combines the impact of solid CO2 pellets with a rapid temperature change to lift and remove particles. This process sublimates, meaning the dry ice transitions directly from solid to gas, leaving no secondary waste aside from the dislodged contaminants.
This technology provides several advantages, including reduced environmental impact due to the elimination of harsh chemicals and water usage. It’s particularly valuable in industries with stringent cleanliness requirements, like electronics manufacturing, medical device production, and historical preservation. The non-abrasive nature of the process makes it suitable for delicate surfaces, while the absence of residual moisture reduces the risk of corrosion and microbial growth. The adoption of this technology represents a significant advancement in cleaning practices since its initial development in the latter half of the 20th century.
