Dry ice blasting is a new and effective industrial cleaning process. It uses dry ice pellets under extreme pressure to blast surfaces clean. Dry ice blasting can replace sandblasting, steam or water blasting, and the use of harmful solvents. This safe, yet powerful, cleaning method is fast becoming the new way to clean in many industrial settings.

WHAT IS DRY ICE?
Dry ice is frozen carbon dioxide (CO2). CO2 is usually found as a gas -- it's what we exhale. To make dry ice, CO2 is compressed, and it liquefies at a pressure of approximately 870 pounds per square inch. The dry ice press then reduces the pressure, and part of the liquid CO2 sublimates (meaning it turns from a solid into a gas). The remaining liquid freezes into flakes that are compacted into solid blocks. The resulting dry ice is denser, heavier, and colder than ice made from water.

HOW DOES DRY ICE BLASTING WORK?
Dry ice blasting technology shoots small pellets of dry ice from a high-pressure nozzle with compressed air. It works somewhat like sandblasting or high-pressure water or steam blasting, but with superior results. Because the temperature of dry ice is so cold (-109.3°F), the blasting process causes the material to be removed to shrink and lose adhesion from the machinery surface it has attached to.

Dry ice blasting is not only efficient, it is also environmentally friendly. Once the dry ice comes in contact with the surface, the dry ice converts back into carbon dioxide gas thus bypassing the liquid state.

Dry ice blasting also causes less wear and tear on the surfaces it cleans as compared to other industrial cleaning methods. Because the dry ice pellets are softer and not as abrasive as other means, it does not damage, wear away, or pit the surfaces it cleans.

Paint, asphalt, tar, decals, soot, dirt, ink, resins, and adhesives are some of the materials that can be removed by dry ice blasting.
