Dry Ice Blasting
Whether you prefer to call it Dry Ice Blasting, CO2 Blasting, or even Cryogenic Blasting, cleaning with super cold dry ice, propelled at supersonic speeds, is a superior industrial cleaning method for equipment and machinery. It’s faster, more cost effective, and an entirely environmentally friendly cleaning technology.
Dry ice blasting is similar to cleaning or blasting with sand but with a major difference. Sand blasting requires that the sand be removed after the cleaning process. Comparatively, dry ice is nothing but frozen CO2 in a pellet form and will sublimate safely back into the atmosphere. With nothing to remove from the site but the dirt, grease, or any number of other contaminants, clean-up is much easier. Dry ice blasting is one of the best ways to clean surfaces without causing damage to equipment being cleaned or to the environment.
Need more cleaning effectiveness? Utilizing high pressure CO2 blasting at 180-200 psi and the cleaning effect of more abrasive materials is realized without the disposal problem of the abrasive itself.
The benefits of using Dry Ice Blasting is extensive, but one of the most convenient differences is that equipment can generally be cleaned where it stands. Using CO2 blasting has a clear advantage over other cleaning methods if the equipment or machinery to be cleaned has electrical components, has to stay dry, or if it’s delicate.
CO2LD TECH is the dry ice (CO2) cleaning division of Blackwell’s Inc. Since 1982, Blackwell’s Inc. has been the source for industrial cleaning throughout the southeastern United States. Should your industrial cleaning require dry ice blasting, confined space work, ductwork, ceilings, production machinery, storage tanks etc., we are the professionals with specialized training and decades of experience. CO2LD TECH Dry Ice Blasting is Georgia based and near Atlanta, serving the southeastern United States including Alabama (AL), Georgia (GA), Florida (FL), Mississippi (MS), North Carolina (NC), South Carolina (SC), Tennessee (TN), and Virginia (VA).
Dry Ice (CO2) Blasting Facts
- CO2 Blasting is also known as Dry Ice Blasting and Cryogenic Blasting.
- The dry ice pellets are made from food grade carbon dioxide approved by the FDA, EPA, and USDA.
- These super-cold pellets (minus 109 degrees F.) are accelerated to super-sonic speeds.
- Frozen CO2 (dry ice) does not evaporate. It sublimates.
- The dry ice pellets used in the blasting process vaporize and expand nearly 800 times on impact with the surface being cleaned.
- The CO2 goes back into the atmosphere.
- Ice Blasting is documented by the Food Standards Agency to effectively decontaminate surfaces of Salmonella, E. Coli, and Listeria.
- CO2 Blasting is considered a non-abrasive cleaning method.
- Dry ice blasting is non-flammable and non-conductive.

Dirty electric motors run hotter and use more energy. Inadequate ventilation from blocked cooling fans can result in bearing failures. Dry ice is non-conductive, so it’s an ideal method to clean electrical equipment.
Clean and dry CO2 blasts electrical motors, circuit boards, switch gears, insulators and windings without the headaches associated with sand or water blasting.
Since the CO2 sublimates back into the atmosphere, there is no need for the electrical components to dry. Electrical components can immediately be put back into service.
A structure fire can be devastating not only for the owner of the building, but for those who rely on it for work or shelter. Aside from immediate damage from the fire, smoke and charring damage can affect surfaces that may have otherwise survived the disaster. Let the dry ice blasting experts at Co2ldtech help you make the restoration process that much easier.
Smoke and Fire Damage
Wood, Brick, Rock and other surfaces that suffered smoke damage and light charring can be scrubbed using CO2 Blasting without the messy residue associated with other cleaning methods. Pressure washing with water, for example, can cause electrical components to get wet, saturate insulation and wood structures, corrode metal, and leave excess water that has to be removed. Likewise, sand blasting leaves behind abrasive grit particles that can damage electrical equipment and contaminates the area with silica dust. Alternatively, the only cleanup required after using dry ice blasting is the removal of the charred materials and particulates.
At Co2ldtech, we go above and beyond to make sure our food industry products are made to the highest standards of quality and safety. Cleanliness in the industry is in the most important factor when it comes to food safety. That’s why food processing companies have some of the most challenging and difficult cleaning opportunities of any industry. Clean equipment helps keep pathogens to lower levels and equipment in good working order.
Effective cleaning removes food particles, sometimes called “food soil”, from food contact surfaces. This helps to remove the material needed for bacteria to grow, while simultaneously killing bacteria that are already present. Dry ice blasting not only achieves this goal safely, but also effectively decontaminates these surfaces of Salmonella, Listeria, and E. Coli. After a single blasting, these microorganisms could not be detected using conventional micro biological methods. (From Microchem Bioscience Limited Project BO2006).
Snack food processing lines and cooking surfaces all clean quickly and easily with dry ice blasting. Labelers, glue assembly areas, Bag-in-Box formers, conveyors, de-nesters, and palletizers can be cleaned weekly or monthly with dry ice blasting.
Industrial silos store many different food materials. Periodic cleaning removes old residues to help prevent contamination of new materials. CO2 blasting also removes the buildup of old residue inside that reduces the volume of the product the filled silo will hold. Because dry ice blasting is a dry cleaning process, silos containing flour or sugar can be cleaned without creating a wet accumulation of residue that’s difficult to remove from the site.
Many CO2 blasting cleaning applications exist. Give CO2LD TECH a call and we will work with you on next cleaning project.
Dry ice blasting to remove cement slurry from brick facing inside a historical department store (circa 1930) undergoing renovation. High pressure water would have damaged the heart pine flooring inside the historical building. Sand blasting would have contaminated the site with silica dust and would leave sand residue for disposal.
The specialized equipment used in today’s industrial processes require specialized cleaning techniques. Dry ice is soft enough to not damage the equipment surface being cleaned. Since no water is used, nothing has to dry. Since no sand or cleaning solvents are used, nothing has to be removed but the contaminant itself, making dry ice blasting a superior method of cleaning equipment and machinery.
Dry ice blasting is an ideal cleaning method to remove contaminants such as:
- Oil and grease
- Food residues
- Soot and smoke stains
- Injection molding residue
