Dry Ice

DRY ICE

Dry Ice is manufactured by compressing and cooling gaseous CO2 under high pressure to initially produce liquid CO2.

The liquid is then allowed to expand under a reduced pressure to produce CO2 snow, and finally, this snow is compressed by a hydraulic press into convenient Dry Ice blocks, slices or pellets.

The density of the compressed CO2 snow depends on the applied pressure and the pressure time. The density of the Dry Ice block can reach 1.56g/cm3 as a maximum at a temperature of -78.64°C.

We manufacture our Dry Ice using the world’s leading dry ice manufacturing equipment. After all, the premier quality of our dry ice can only be achieved through best-practice manufacturing techniques.

How to Store Dry Ice

Dry ice should be stored in a well-insulated container outside, like a cooler, with the lid only slightly closed. The thicker the insulation the better, as it will turn back into a gas at a slower rate. Never store it in an sealed container as the sublimated CO2 gas will sink and can be dangerous. If airtight, it can make a dry ice bomb causing the container to explode.

You might think the freezer is a great place to keep it cool but it actually too warm. Due to the low temperature of dry ice it could cause your fridge to turn off.

The Many Uses of Dry Ice

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.

Emergency Refrigeration and Power Outages:

Use dry ice to maintain refrigerator and/or freezer while power is out.  The right amount of dry ice can maintain the cold for up to three days. Camping, Hunting, Fishing, Tailgating, Boating, etc

Use dry ice to keep food and beverages cold all day without the water mess found with regular ice. You can use dry ice to bring game or fish home frozen.

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

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.

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.

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 5 pounds 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.

Remove car dents :

Dry ice can be used to remove car dents and dings as long as there is no crease on the bottom and the sheet metal is not bent.  Allow the dent to sit in the sun to warm up (or use a blow dryer).  Take a 10 pound slab of dry ice and place directly over the dent.  The rapid cooling of the metal will pop the dent back to normal.  There is a very small risk of paint scratching with this method however it is quite rare (use at your own risk)

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.

Lures mosquitoes away :

Mosquitos love dry ice!! ‘Why???  The reason mosquitos are attracted to both animals and humans is because when exhaling, we produce small amounts of CO2 (Carbon Dioxide).  When CO2 is detected by a mosquito, is registers the location of it’s next meal of blood.  As dry ice sublimes to CO2 gas, it’s equivalent to over 1,000 people breathing at the same time in a close proximity.  Therefore the mosquito will zoom in on the dry ice because of the high concentration of 100% pure CO2 gas that dry ice expels. Place 5-10 pounds pieces of dry ice away from areas where people are gathered.  Works amazing!

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.
