Imagine an industrial cleaning media that's non-abrasive, disappears on contact and is versatile enough to be used for everything from heavy slag removal to delicate semiconductor and circuit board cleaning.

Frozen C02 Pellets Fired at Supersonic Speed..

Dry ice blasting is an environmentally friendly process utilizing solid CO2 pellets accelerated in a pressurized air stream to impact a surface to be cleaned or prepared. Instead of using hard abrasive media such as sand or glass to grind on a surface (and damage it), dry ice blasting uses soft dry ice, accelerated at supersonic speeds, and creates mini-explosions on the surface to lift the undesirable particulates off the underlying substrate.

No Residue, Limited Cleanup, Superior Performance..

In dry ice blasting, the temperature difference between the dry ice particles (-109º Fahrenheit or -78.3º Centigrade) and the surface being treated, creates thermal shock, breaking the bond between the substrate and the contaminant to be removed. Upon impact, the pellets sublimate (convert directly from a solid to a vapor) leaving no residue and limiting cleanup to the undesired particulates only. The process is superior to sand blasting, glass bead blasting and other types of cleaning methods for a number of different reasons.

Safe Environment, Non-toxic cleanup, Non corrosive..

With water blasting or Steam cleaning the process creates a wet environment which is unsafe for employees and most equipment. It is considered a wet process therefore there is additional time in waiting for the equipment to dry. The cleaning of or around toxic or hazardous items will contaminate the water which is extremely costly to dispose of appropriately. Both are highly conductive, corrosive, potentially could damage electrical components and bearings and encourage the generation of bacteria, mold, mildew and fungus.

Low Cost Disposal, Non-Damaging On Surfaces..

With abrasive blasting media there is a significant cost incurred in the cleaning and disposal of the media itself, regardless if toxic or hazardous items are present. If they are, the media is also considered contaminated and must be disposed of appropriately. It is unsafe to use on certain surfaces such as plastic, glass, rubber, electrical components, and bearings. Depending on the media, equipment damage can occur due to media particulates getting lodged in cavities and crevices. In addition, abrasive media stresses the substrate by wearing, pitting and eroding surfaces.
