Dry Ice

We hold expertise in offering a quality range of Dry Ice to the customers, which is solid carbon dioxide. Dry ice sublimates and also changes directly to the gas form at different atmospheric pressures. The low temperature as well as direct sublimation to a gas further makes dry ice an effective coolant. Our customers can purchase these from us at market leading prices as well.

About Dry Ice - What is Dry Ice?

Dry ice is the solid form of carbon dioxide (CO2). It's called "dry ice" because it does not melt like wet ice. Instead, dry ice converts into carbon dioxide gas. Because dry ice is extremely cold ( -109°F/-78.5°C), non-toxic, and completely dry, it is commonly used as an expendable refrigerant to ship frozen food or medical products or to cool materials during production. The other major use of dry ice is for dry ice blast cleaning, an effective and environmentally friendly way to clean industrial equipment.

Safe Handling of Dry Ice
Remember these safety precautions when you work with dry ice!

Handling

Dry ice is -109º F, which is cold enough to freeze skin cells causing an injury similar to a burn. Never allow dry ice to come in contact with skin. Always handle dry ice with protective gloves or a towel.

Ventilation

Dry ice converts to carbon dioxide gas. If left in a confined space, the carbon dioxide gas will displace oxygen and present a suffocation hazard. If dry ice has been in a confined space (e.g. a closed car or room) for more than 10 minutes, open the doors and windows before entering or you could experience difficulty breathing. Leave the area immediately if you start to breathe quickly or have any difficulty breathing.

Storage
Do not store dry ice in a container that is completely airtight. When dry ice sublimates to carbon dioxide gas, the gas pressure greatly expands. This expansion will cause an airtight container to expand and possibly explode.

 

Dry Ice Fact Sheet

You cannot store dry ice as it is -80 degrees, therefore it will disappear even if stored in a freezer. You need to obtain it or have it delivered close to the time it will be used.

The only way of storing it effectively is by use of an insulated container with a lid – you should also pack any remaining space in the container with wadded newspaper in order to decrease the oxygen content. Basically you are trying to ‘suffocate’ the dry ice in order to keep it in a solid form for as long as possible. You would still lose in excess of 50% over a 24 hour period.

Dry Ice is supplied in individually wrapped 1kg slices, or you can request that we crush it into pellets for you although when ordering pellets you will lose a small amount due to exposure to the atmosphere during the crushing process.

It is quite impossible to advice on how to use dry ice and the quantity that you will need, as it is not an exact science. You really need to experiment with it personally.

Water temperature affects the characteristics of the fog created. Hotter water or steam vaporizes the carbon dioxide more quickly, yielding lots of fog and using up the dry ice more quickly. If fresh hot water or steam isn't added, the remaining water will cool quickly.

Dry ice increases the level of carbon dioxide in the air where it is used. This can present a respiratory hazard low to ground (or downstairs, if applicable), in enclosed spaces, or with large quantities of dry ice. Do not transport dry ice in the passenger compartment of your vehicle; it must only be placed in the boot of the vehicle.

Orders for dry ice generally need to be placed at least one day before delivery, as it will not be loaded onto the van unless it has been ordered in advance.
