What can I use Dry Ice for?

Dry Ice is used in commercial, Industrial, entertainment, and recreational activities and applications. Examples of dry ice usage include: dry ice blast cleaning, metal fabrication, meat processing, preserving frozen foods, preserving frozen samples in research labs, emergency refrigeration, power outages, shipping food & perishables, camping, picnicking and fog production for plays, theater & shows. Ship cold items a long distance. If you want to send something frozen across the country, you can pack it in dry ice. It will be frozen when it reaches its destination, and there will be no messy liquid left over like you would have with normal ice.

What should I know for when I come in to purchase?

We recommend bringing in a cooler with a blanket or towel. The reason we recommend this is it keeps the dry ice insulated in the cooler with a towel or blanket as insulation slows down the rate the dry ice sublimates, increasing the time it will last for you. We also recommend not keeping your dry ice in your freezer at home because the fans will cause the dry ice to sublimate faster, and could damage your freezer.

What is Dry Ice?

Dry ice is frozen carbon dioxide. A block of dry ice has a surface temperature of -109.3 degrees Fahrenheit (-78.5 degrees C). Dry ice has a helpful feature called sublimation: ‘As Dry Ice breaks down, it turns directly into carbon dioxide gas rather than a liquid.’ The super-cold temperature and the sublimation feature make dry ice great for refrigeration. Because of this extremely cold surface temperature never hold it without gloves.

How do you make Dry Ice?

To make dry ice, you start with a high-pressure container full of liquid carbon dioxide. When you release the liquid carbon dioxide from the tank, the expansion of the liquid and the high-speed evaporation of carbon dioxide gas cools the remainder of the liquid down to the freezing point, where it turns directly into a solid. If you have ever seen a carbon-dioxide fire extinguisher in action, you have seen this carbon-dioxide snow form in the nozzle. You compress the carbon-dioxide snow to create a block or pellets of dry ice.

How much dry ice sublimation can I expect each day?

The answer depends on several factors including the environmental temperature where the dry ice is stored, how often the storage container is being accessed, etc. We’ve found the sublimation rate to be around 6% per day the first week when kept in our professional containers. Over-the-counter coolers can expect a higher (faster) sublimation rate.
