The Compressed Air Supply

Although Cold Jet dry ice equipment is designed and engineered to work under the most
•
demanding environments and conditions, the incoming air supply must be as free of oil,
dirt/foreign particles, and water/moisture as possible.
o For example, oil-laden air will contaminate the entire system including any articles being
dry ice blast cleaned.
Contaminants such as dirt/foreign particles will score or even clog interior mechanical parts
•
resulting in poor machine function.
Dirt/foreign particles in the compressed air can strike the article causing damage to the surfaces
•
being dry ice blast cleaned.
The results of frozen water and/or moisture can be:
•
o "Water-ice" - It is a very good adhesive; internal parts may freeze together and seize the
machine.
o Loose water-ice pieces could build up and cause clogs in the hose, particle control
assembly, feeder and/or nozzle.
o Water-ice is harder than dry ice and may cause damage to the article being dry ice
cleaned.
o When water-ice melts, water is left behind. (Dry ice sublimates, meaning it turns to a gas.)
Water can be a slip hazard and may increase the speed at which corrosion may occur.
Particular attention must be paid to water. Water or moisture laden air can be especially
•
troublesome once it is introduced to dry ice. (In this case, "moisture" is referred to as water in
vapor form.) For example, dry ice is -109F (-78C), water/moisture will immediately freeze and may
cause problems.
The incoming air quality must meet the standards in the chart provided in the Required Air Quality
•
section of this manual. In addition, it is recommended that the incoming supply air and any
