Dry Ice Applications

What Can Dry Ice Be Used For?

ACCELERATED PLANT GROWTH

A small quantity of CO2 will increase the growth rate of plants.  Allow the dry ice to sublimate in close proximity to the plants for 10-15 minutes daily.

ASPHALT COOLING

Using dry ice allows for the delicate asphalt to stay at required temperatures during transport from the manufacturing plant to job site.  Even more beneficial, using dry ice allows contractors to speed up the cooling process and core the paving sooner.

BED BUG REMOVAL

Infestation of bed bugs has become a serious problem because most of the chemicals used to control them are now banned or restricted. Removal of small infestations or testing whether you have them is possible by building a trap using dry ice.

BROKEN FREEZER

Use dry ice to keep freezer contents frozen during breakdowns.

BROKEN REFRIGERATOR

Use dry ice to keep refrigerator contents cool during breakdowns.

CAMPING

Dry ice provides the most effective and inexpensive means to keep perishables chilled or frozen.

CARBONATE LIQUIDS

When dry ice is added to liquids, the dry ice will sublime and become a gaseous CO2 vapor.  During this process, the liquid will absorb the CO2 gas and become a carbonated liquid, AKA fizzy pop, Sparkling water, etc. CO2 is extensively used around the world in the beverage and soft drinks industry.

CHEMOTHERAPY

Many cancer patients undergoing chemotherapy treatments have found the use of super cooled “cold caps” to be an effective way to reduce or prevent hair loss.

CONTAINMENT TANK REPAIR / REMOVAL

Dry ice will remove oxygen from flammable containment tanks if placed inside, reducing the risk of flammable vapours catching spark and exploding.

DE-FLASHING MOLDED PLASTICS & RUBBER

Dry ice causes molecules to band closer together and shrink.

DRY ICE BLASTING

Dry ice blasting has become the fastest growing application of CO2 in the entire industry.  Similar to sand blasting, dry ice blasting uses a jet nozzle and compressed air to shoot small pellets of dry ice (blasting rice) with superior results.  The extreme cold causes targeted material to shrink, allowing for easier removal.  The used blasting rice will sublimate into gaseous CO2 after use which makes cleanup a breeze.

FLASH FREEZING SUSHI / FISH

Dry ice can be used to flash freeze fish, ensuring freshness and prolonging preservation time by up to ten days longer than regular ice.

FOG VISUAL EFFECT

Dry ice when combined with hot water will produce and awe-inspiring display of bubbling water and thick voluminous fog.  Use a 2kg  of dry ice for every 4L of hot water for 5-10 minutes of maximum effect.  Since dry ice retains a temperature of  -78°C, the water will cool rapidly.  Replace with hot water to maintain desired effect.

FREEZING FRESH FRUITS

Place dry ice in the bottom of your cooler and the fruit directly on top. Close cooler and let fruits freeze for 20-30 minutes. Remove fruit and place in freezer safe plastic bags as needed.

FRESH MEAT PROCESSING

Dry ice will keep the temperature cold and reduce spoilage while processing meat. This is used in industrial processing of ground meats and sausages.

GREEN BURIALS

Dry ice can be used to preserve the human body until the funeral.  This method has been proven more environmentally friendly than the use of toxic, embalming chemicals, and MUCH less expensive.

INERTING MEDIUM

Dry ice will replace oxygen in a container preventing or extinguishing fires. The most common use is for safely removing underground gas storage tanks.

KILLS CLOTHES MOTHS

Dry ice, when combined with heavy plastic bags can kill moths, larvae, and eggs through fumigation.  Place clothes for fumigation in a plastic bag (at least 3mm thick).  Wrap 4kg  of dry ice in a towel/rag and place inside the bag.  Seal the bag but ensure there is enough space for the sublimation to escape rather than building pressure.  20-30 minutes should be adequate time to finish the job.

LURES MOSQUITOS AWAY

Dry ice, when combined with heavy plastic bags can kill moths, larvae, and eggs through fumigation. Place clothes for fumigation in a plastic bag (at least 3mm thick). Wrap 4kg of dry ice in a towel/rag and place inside the bag. Seal the bag but ensure there is enough space for the sublimation to escape rather than building pressure. 20-30 minutes should be adequate time to finish the job.

MEDICAL USES

There are a number of applications in the medical field. Doctors will often use dry ice to freeze and remove warts or other skin imperfections. Temperature sensitive medical supplies, samples, and equipment are also commonly transported with dry ice as a cooling agent.

PLUMBING

Dry ice can be used to freeze pipes, essentially stopping the flow of water at point of contact. This method is very useful if you are unable to access the main shutoff valve. Once the pipes are frozen, proceed with repairs.

PRESERVE SEEDS & GRAINS

Dry ice can be used to protect post-harvested seeds and grains from bacteria, fungi, and insects. Place what you desire to store into a storage container with a small vent on top. Add dry ice to container (amount varies depending on container size). The dry ice will sublimate into gaseous CO2 and displace oxygen and keep contents at low temperatures to kill fungi and bacteria.

REMOVE SKIN IMPERFECTIONS

Dry ice is sometimes used either with or as a substitute to liquid nitrogen to remove small skin imperfections, warts, and moles. This method is not to be used at home.

SCHOOL SCIENCE & EXPERIMENTS

There are a multitude of fun, creative science projects and experiments to be used in schools. Volcanoes, cloud chambers, comets, making baking soda, observing sublimation and gaseous expansion.

SHRINK METAL FITTING

Dry ice works wonders for metal shrinking and fitting for all types of industry.

SPECIAL FX & THEATRICS

Using a fog machine or buckets of hot water and a fan, many shows are enhanced by adding flowing fog, great for Halloween, stage plays and shows.

WELDING MOTORCYCLE TANKS

Use a similar method as when purging containment tanks, the main idea is to use the dry ice to sublimate and displace oxygen before welding. Be sure to eliminate all traces of fuel and wash out the tank with warm soapy water.

BRANDING CATTLE & HORSES

Freeze branding using copper irons chilled by dry ice has become the preferred method for ownership marking.  This technique actually freezes the animal’s hair follicles, causing the branded area to grow highly visible white coloured hair.  More and more livestock owners are turning to this more humane option.
