Dry ice blasting is similar to sand blasting, plastic bead blasting, or soda blasting where a medium is accelerated in a pressurized air stream to impact a surface to be cleaned or prepared. But that’s where the similarity ends.

Instead of using hard abrasive media to grind on a surface (and damage it), dry ice blasting uses soft dry ice, accelerated at supersonic speeds, and creates mini-explosions on the surface to lift the undesirable item off the underlying substrate without leaving secondary waste.

How does CO2 Blasting Work?

CO2 blasting works because of three primary factors: pellet kinetic energy, thermal shock effect and thermal-kinetic effect. This optimizes blast performance for each application by combining these forces and adjusting:

  • compressed air pressure
  • blast nozzle type (velocity distribution)
  • CO2 pellet size and density
  • pellet mass rate and flux density (particles per unit area per second)

Dry ice blasting has many unique and superior benefits over traditional blasting media.

  • Non-abrasive & nonflammable
  • Environmentally-friendly
  • Approved for use in the food industry
  • Can clean items without disassembly
  • Safe for electrical/mechanical parts
  • Removes residues, paints, oils & biofilms
  • Gentle enough to restore damaged books
  • Aggressive enough to remove weld slag
