Dry Ice Pellets:

• • Made from compressed and frozen carbon dioxide gas.
  • Pellets sublimate (turn directly from solid to gas) upon impact, leaving no residue behind.

Blasting Machine:

• • Equipped with a hopper for dry ice pellets and an air compressor.
  • Delivers the pellets at high speed through a specialized nozzle.

Compressed Air:

• • Provides the pressure needed to propel the pellets.
  • Air pressure is adjustable to suit different cleaning applications.

Preparation:

• • Assess the surface or object to be cleaned.
  • Protect any areas or equipment that shouldn’t be exposed to the blasting process.

Cleaning:

• • The operator directs the nozzle at the target surface.
  • Dry ice pellets are propelled at high speeds, creating a thermal shock when they hit the surface.
  • This causes contaminants to shrink, loosen, and detach without harming the underlying material.
  • The dry ice sublimates instantly, leaving only the dislodged debris to clean up.

Cleanup:

• • Since the dry ice evaporates into CO₂ gas, the only cleanup required is removing the loosened debris.

The duration depends on factors such as:

Size of the Job:

• • Small equipment or tools may take a few minutes to an hour.
  • Larger projects, like industrial machinery or building restoration, may take several hours to a few days.

Type and Thickness of Contaminants:

• • Grease, grime, mold, or soot buildup affects the time required. Thick layers of stubborn materials will take longer to clean.

Surface Complexity:

• • Smooth, flat surfaces are quicker to clean compared to intricate or hard-to-reach areas.

Blasting Equipment and Operator Experience:

• • Advanced equipment and skilled operators can significantly reduce cleaning time.

Light Cleaning:

• • 1–2 hours (e.g., removing surface dust or light grime).

Moderate Cleaning:

• • 4–8 hours (e.g., grease and oil on machinery).

Heavy Duty Cleaning:

• • 1–2 days or more (e.g., fire damage restoration or large industrial sites).
