Dry ice blasting uses compressed air to accelerate solid carbon dioxide (CO2) dry ice pellets to literally strip industrial equipment surfaces of a multitude of residues, including ink, glue, paint, food, rubber, mold release agents, dirt, grease, oil, and numerous other contaminants. Dry ice blasting is similar in principle to sand blasting. Instead of sand, dry ice blasting uses high-density dry ice pellets which are propelled onto a surface using compressed air. Unlike sand blasting, dry ice blasting is non-abrasive. When dry ice pellets hit a surface, such as a metal part contaminated with oil and grime, the dry ice pellets immediately sublimate [change in form from solid to gas]. Dry ice blast cleaning leaves no residue like sand blasting, and it leaves no toxic waste as solvents can. It lets you skip clean-up problems associated with other cleaning methods. |

This environmentally friendly industrial cleaning process will not damage electrical wiring and controls, switches and relays, or bearings. Dry ice blasting leaves no thermal shock in the metal. The temperature gradient occurs only on the surface and is much less than average treatments during processing.
A wide range of industries can benefit from dry ice blasting because it is:

Ice Blasting: What is It?
It is a process in which particles of solid carbon dioxide (CO2)are propelled at supersonic airstream velocities to achieve the impact energy to strip and clean surfaces. When CO2 pellets impact, they compress and mushroom out into a high velocity snow, then instantly sublimate back into its natural state as a gas. This creates a compression tension wave. The gas expands to nearly 800 times the volume of the pellet in milliseconds in what creates a small series of micro-explosions at the impact point. The punctual thermal shock also known as "fracking" along with the airstream velocity and the surfaces decreasing temperature serves to break up the coating as it becomes embrittled. As the molecular bond decreases, it simply pops off the contaminant from the inside out.
This method has improved cleaning standards of companies throughout a broad range of industries worldwide with considerable increases in productivity, product quality, and environmental responsibility coupled with substantial savings.
