What’s dry ice blasting?

Dry ice blasting is a cleaning method that uses compressed air to accelerate dry ice particles, removing surface contaminants without toxic solvents. It is non-abrasive, non-conductive, and non-flammable, making it ideal for use on electrical equipment. Dry ice blasting can save time, reduce equipment breakdowns, and eliminate excessive waste removal. It is also safe for the environment and human exposure. Certified technicians provide on-site services for industries such as high-tech, manufacturing, and food.

Dry ice blasting is an industrial cleaning method that uses abrasive spray from wand, hose, and cabinet equipment, accelerating dry ice particles with compressed air to remove unwanted surface contaminants. Dry ice is carbon dioxide (CO2) frozen into pellets. The ice grains explode on impact, hiding behind layers of contaminants, and then convert to gas. This kicks up contaminants, while the gas escapes harmlessly into the atmosphere. Dry ice, or CO2 blasting, has become a popular solution in the high-tech, manufacturing and food industries.

A number of benefits arise from the use of dry ice blasting. This portable technique can save time by reducing equipment breakdowns and assembly, and by eliminating the excessive waste removal that characterizes other cleaning techniques, such as blasting. Provides quick and thorough cleaning while reducing damage to surfaces. Intensity can be calibrated from light tweaks to extremely powerful designs; for example, dust burn damage from books or weld slag from tools.

Abrasive dry ice blasting may be safer for the environment and for human exposure, as it does not require toxic solvents to achieve thorough cleaning, even where scrubbing tools cannot reach. Labor costs can be reduced because cleaning projects can be reduced from days to hours. Transfer costs can be reduced or eliminated.

Carbon dioxide has several advantages over traditional blasting media. A cheap and non-toxic liquefied gas, CO2 is easy to store and can even be created on construction sites. Dry ice blasting provides a non-abrasive, non-conductive, non-flammable cleaning medium that will not damage electrical equipment. It can remove many common industrial contaminants such as spills, release agents and residues or oils and varnishes. Food industries have adopted this method and dry ice pellets made from food CO2 are available.

The dry ice blasting technique involves a three-step process: energy transfer, micro-thermal shock, and gas pressure. The energy transfer drives the dry ice pellets from a spray wand with compressed air at supersonic speed. At a temperature of -109°F (-78.3°C), the pellets create a microthermal shock between the substrate and the contaminant. The contaminant breaks down and delaminates the surface. The pellet explodes on impact and heats to a gaseous state, which expands under the residue; the pollutant falls and the gas is harmlessly dispersed into the air, leaving only the unwanted material for faster cleaning.

Certified technicians or contractors provide on-site trained dry ice blasting services. CO2 provides fast, non-toxic and non-harmful cleaning with the same material used in carbonated drinks. The non-abrasive technique can be used on electrical and rubberized components, equipment, heavy machinery building structures and more. By eliminating strenuous physical labor, toxic solvents, and secondary waste, dry ice abrasive blasting can provide industries with a cost-effective cleaning method that can improve productivity, employee safety, and product quality.
