Dry ice blasting, also know as CO2 blasting or cryogenic blasting is a newer method of cleaning. The process of dry ice blasting consists of dry ice pellets being propelled out of a pressurized air stream. Dry ice is the solid form of carbon dioxide. This method can be useful in many situations as it is completely non-abrasive and non-toxic. It is commonly used in restoration processes for smoke, fire, water and mold remediation. Dry ice blasting is also great for cleaning equipment in the food industry as well as for factory equipment cleaning.
Dry ice is environmentally friendly and does not leave behind harmful, harsh chemicals or residue. As soon as the dry ice pellets make contact with a surface they will sublimate. This means that directly on impact with the surface the dry ice will immediately change from its solid state to a gas. There is a science to this process but in the most basic, simplified terms when the dry ice is blasted at a high rate of speed, it causes the coating of the surface to freeze and crack. As the dry ice sublimates, a large amount of energy is released which will strip off the surface’s coating. It is a very effective process in cleaning and removing any contaminants, oil, grease, paints, rust and mold spores.
This type of media blasting is extremely fast and thorough. It is not necessary to disassemble any equipment and the dry ice can reach and effectively clean out the smaller and more difficult spaces. Chemicals are of no concern and there is no need for any drying time. This will significantly cut down on any downtime of equipment. Damage to equipment or any other surface is not a worry since this method is so gentle and non-abrasive. Another benefit is that it is completely safe to use around all types of electrical equipment from panels and switches to wiring.
These are all some of the many reasons why this method has largely become a preferred cleaning method in many industries.
