Dry ice blast cleaning utilizes a unique combination of forces to powerfully lift surface contaminants without causing damage or creating harmful secondary waste. Similar to sand, bead and soda blasting, dry ice blast cleaning prepares and cleans surfaces using a medium accelerated in a pressurized air stream. 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.

Dry ice blasting:

  • is a non-abrasive, non-flammable and non-conductive cleaning method
  • is environmentally responsible and contains no secondary contaminants such as solvents or grit media
  • is clean and approved for use in the food industry
  • allows most items to be cleaned in place without time-consuming disassembly
  • can be used without damaging active electrical or mechanical parts or creating fire hazards
  • can be used to remove production residue, release agents, contaminants, paints, oils and bio-films
  • can be as gentle as dusting smoke damage from books or as aggressive as removing weld slag from tooling
  • can be used for many general cleaning applications

Cold Jet dry ice blasting uses compressed air to accelerate frozen carbon dioxide (CO2) “dry ice” pellets to a high velocity. A compressed air supply of 80 PSI/50 scfm can be used in this process. Dry ice pellets can be made on-site or supplied. Pellets are made from food grade carbon dioxide that has been specifically approved by the FDA, EPA and USDA.

Carbon dioxide is a non-poisonous, liquefied gas, which is both inexpensive and easily stored at work sites.
