CO2 (Dry ice) Blasting
The rising star in industrial cleaning applications
Cold Jet dry ice blasting is an efficient and cost-effective way for industries
to maximize production capability and quality.

What is Dry Ice Blasting?

 Dry Ice Blasting Blasting

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. If you want to read all the technical details, see the How CO2 Blasting Works page.

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

  • is a non-abrasive, nonflammable and nonconductive cleaning method

  • is environmentally-friendly 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 residues, release agents, contaminants, paints, oils and biofilms

  • 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, the EPA and the USDA.

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

What is Dry Ice?
 and How is it made

Dry Ice

Cold Jet's high-density dry ice products are optimized for all industrial and commercial applications including food freezing and shipment, metal fitting, dry ice blasting, and many other uses.

To ensure optimum results, Cold Jet developed patented technology that produces high-quality, high-density dry ice products.

CO2 is a natural medium, which serves many life sustaining purposes. It is a key element involved in the carbon cycle; it is the only source of carbon for the carbohydrates produced by agriculture; it stimulates plant growth; and it helps to moderate the overall temperature of the earth. Animal respiration is believed to add 28 million tons of carbon dioxide per day into the atmosphere. By contrast, the U.S. CO2 industry can supply only 25,000 tons per day and 95% of this amount is from by-product sources, or less than 0.04% of the other sources combined.

With a low temperature of -78° C, dry ice solid has an inherent thermal energy ready to be tapped. At atmospheric pressure, solid CO2 sublimates directly to vapor without a liquid phase. This unique property means that the dry ice blast medium simply disappears, leaving only the original contaminant to be disposed of. In addition, cleaning in water sensitive areas (e.g. in the vicinity of electrical cabinets) is now practical.

The grade of carbon dioxide used in blasting is the same as that used in the food and beverage industry and has been specifically approved by the FDA, the EPA and the USDA. Carbon dioxide is a non-poisonous, liquefied gas that is both inexpensive and easily stored at work sites. Of equal importance, it is nonconductive and non-flammable.

CO2 is a natural by-product of several industrial manufacturing processes such as fermentation and petrochemical refining. The CO2 given off by the above production processes is captured and stored without losses until needed. When the CO2 is returned to the atmosphere during the blasting process, no new CO2 is produced. Instead, only the original CO2 by-product is released.
