Drysnow generates dry ice particles directly from liquefied carbon dioxide, which are then blasted. This allows for the removal of adherent materials without damaging the object. It is suitable for cleaning particles, grease, glue-like materials, as well as confined areas.
Dry ice particles have a Mohs hardness of 2, are softer than plastic, and are snow-like particles with an average size of about 30 μm. Hence, they do not scratch plastics. This is what makes it different from typical dry ice blast cleaning systems, which use crushed dry ice blocks.
Also, no water is required, and the dry ice particles sublimate and disappear, eliminating the need for a drying process. No waste is produced, and carbon dioxide is noncombustible and nontoxic, making this an environmentally friendly cleaning system.
Characteristics of Drysnow cleaning
- No damage to the target: Cleaning with soft dry ice particles.
- No secondary treatment required after cleaning: Dry ice sublimates and disappears in an instant.
- High cleaning effectiveness: Better than many cleaning methods.
- Environmentally friendly: As an alternative to high-pressure water and solvent cleaning.
