 Dry Ice

Dry Ice is frozen carbon dioxide, a normal part of our earth's atmosphere. It is the gas that we exhale during breathing and the gas that plants use in photosynthesis. It is also the same gas commonly added to water to make soda water. Dry Ice is particularly useful for freezing, and keeping things frozen because of its very cold temperature: -109.3F or -78.5C. Dry Ice is widely used because it is simple to freeze and easy to handle using insulated gloves. Dry Ice changes directly from a solid to a gas -sublimation- in normal atmospheric conditions without going through a wet liquid stage. Therefore it gets the name "dry ice."

As a general rule, Dry Ice will sublimate at a rate of five to ten pounds every 24 hours in a typical ice chest. This sublimation continues from the time of purchase, therefore, pick up Dry Ice as close to the time needed as possible. Bring an ice chest or some other insulated container to hold the Dry Ice and slow the sublimation rate. Dry Ice sublimates faster than regular ice melts but will extend the life of regular ice.

It is best not to store Dry Ice in your freezer because your freezer's thermostat will shut off the freezer due to the extreme cold of the Dry Ice! Of course if the freezer is broken, Dry Ice will save all your frozen goods.

Commercial shippers of perishables often use dry ice even for non frozen goods. Dry ice gives more than twice the cooling energy per pound of weight and three times the cooling energy per volume than regular water ice (H2O). It is often mixed with regular ice to save shipping weight and extend the cooling energy of water ice. Sometimes dry ice is made on the spot from liquid CO2. The resulting dry ice snow is packed in the top of a shipping container offering extended cooling without electrical refrigeration equipment and connections.

High-Density Dry Ice Blasting Pellets
High-Density dry ice blasting pellets
High-density 1/8" pellets for dry ice blasting specifically designed for high performance during demanding cleaning jobs using blasting machines and compressed air.

Dry ice blasting offers a practical and affordable alternative to traditional cleaning methods such as sand or water blasting. Dry ice blasting is an environmentally friendly way of cleaning machines and more.

Dry ice blasting, also known as dry ice cleaning, dry ice blast cleaning, CO2 blasting, cryogenic blasting or cryogenic cleaning, is a tried and true method of dry cleaning. Dry ice blasting circumvents costly and hazardous chemicals. By using specially-designed dry ice blasting machines in combination with high density [HD] dry ice pellets, dry ice blasting can cut down on your cleaning time by hours or days.

About the Dry Ice Blasting Process

Kinetic Energy is transferred by the accelerated dry ice pellet as it hits the surface during the dry ice blasting process. The dry ice pellet sublimates (changes from solid to gas) upon impact and is softer compared to other cleaning media such as sand, grit or beads. Dry ice blasting is nonabrasive and will not damage most substrate materials or affect tool tolerances.

Thermal-Shock Effect occurs when dry ice pellets 109 degrees below zero strike a much warmer, contaminated surface during dry ice blasting. The extremely cold temperature of the dry ice causes the bond between the surface being cleaned and dirt, grime, and other residues to weaken. This effect aids in the release of the contaminant when struck by the dry ice pellets during dry ice blasting.

Thermal-Kinetic Effect combines the impact of sublimation and the rapid heat transfer discussed above. When the dry ice pellet hits the contaminated surface, the vapor expands so much (up to 800 times the volume of the pellet) and so fast that a micro-explosion occurs, taking off dirt and grime in the dry ice blasting process.

No matter what your cleaning challenge, Diamond Dry Ice Blasting gets results. Dry ice blast cleaning uses non-toxic, non-hazardous, high-density dry ice pellets in a high-velocity airflow to blast away unwanted surface materials. On impact, the pellets instantly sublimate without generating any secondary waste, so it's a greener way to clean. Just check out our photo section to see for yourself. And, dry ice blasting meets EPA, USDA, and FDA guidelines.
