dry ice
Dry ice is the best refrigerant known to man. It keeps things cooler for longer, translating into cost savings for you. When correctly applied and handled it is superior to all mechanical refrigeration in performance, reliability and cost.
We cater to the following clientele:
|
• Laboratories
• Universities & Schools
• Caterers
• Drug manufactures
• Hospitals
• Specialty food processors
|
• Special effects companies for TV and Film
• Baked product producers
• Meat processors
• Refineries
• Transport companies
• Hunters/campers

Camping
Ideal for prolonging food refrigeration when outdoors.
Cold Grinding
Dry ice keeps hard to grind materials such as Plexiglas, PVC Resins, Vinyl, and Epoxy Brittle for fast and easy flash removal.
De-flashing
Rubber parts are tumbled in a barrel with dry ice, making them brittle to facilitate flash removal.
Events & Celebrations
Dry ice creates a spectacular smoke and fog effect that is perfect for birthdays, weddings, theatre, and Halloween. It can also be used in class experiments in order to raise students' interest in science.
Lab Use
Dry ice is used for low temperature testing and is often used for transporting specimen samples.
Metallurgy
Dry ice is ideal for shrink fitting metal. Metal parts are immersed in dry ice prior to fitting. After the parts are fitted, they are warmed to room temperature and a strong fit is achieved.
Perishables
Wild game and fish can be packed in dry ice for transport.

safe handling [ pdf version ]
1. Dry ice has a surface temperature of between -78 and -110 degrees Celsius.
2. Not wearing gloves when handling the product will result in extreme frostbite.
3. Always keep dry ice away from children.
4. Do not swallow, or put dry ice in your mouth.
5. Do not put dry ice in anyone’s clothing for fun. Potentially severe frostbite may occur as a result of prolonged contact with the skin.
6. Do not place dry ice inside an air tight container. Sublimed vapors will increase the interior pressure and will rupture the container.
7. Place a thick layer of cardboard, Styrofoam or similar separator between food and liquid products which need to be chilled. Food and liquid products in containers will freeze when their container is placed in contact with dry ice over a short period of time.
8. Dry ice does not “melt” into a liquid. A process called “sublimation” occurs. Sublimation is when a solid substance skips the liquid state, and goes directly into a gas from it’s original solid state.
9. Dry ice is solid carbon dioxide that expands to a gas. You can loose consciousness by directly breathing in the dry ice vapors for an extended period of time. You will sense carbon dioxide by a “tingling” sensation in the mouth.
Always, always, always BE CAREFUL WITH DRY ICE!!!!!!

frequently asked questions [ pdf version ]
Q: What is dry ice?
A: Dry ice is a name that is applied to compressed carbon dioxide.
Q: What temperature is the surface of dry ice?
A: Dry ice has a surface temperature between -78 and -110 degrees Celsius
Q: Does it melt?
A: No. Dry ice goes through a process called “sublimation” in which a solid substance skips the liquid state and changes directly into a gaseous state.
Q: How is dry ice created?
A: Under normal conditions, carbon dioxide is a colourless and odorless gas. To make carbon dioxide snow (dry ice) the gas is cooled at high pressure which liquefies the gas. Further cooling takes the carbon dioxide to the, “triple point.” The highly pressured liquid is then suddenly expanded by spraying, and turns it into snow. The snow is then pressed into blocks weighing between 50-250 lbs.
Q: How much of the liquid carbon dioxide turns to snow?
A: About 30% of the liquid which is sprayed turns to snow. The rest is turned back into gas and is returned to the compression and cooling process.
Q: What will prevent the dry ice from turning into a gas again?
A: Nothing will prevent the dry ice from “subliming.” Once it is out of the high pressure it must be insulated to reduce the rate of sublimation.
Q: What should dry ice be put into, to insulate it?
A: a “kraft” paper bag will reduce the sublimation rate on its own. The ice wrapped in the paper should be put into a container which is insulated as much as possible, but NEVER seal the ice into an air tight container due to the pressure.
Q: what is the “triple point?”
A: When carbon dioxide is subject to a temperature of 69-degrees Celsius and also to a pressure of 60.4 psi, carbon dioxide can exist as a solid, a liquid and a gas at the same time. The ability to be in three states simultaneously is known as the triple point effect.
Q: Does The Iceman Provide containers to ship the dry ice in?
A: Yes. We offer Styrofoam containers called styro-shippers which can hold capacities of 9.5L to 8L.
Q: How heavy is dry ice?
A: A block measuring 10” x 10” x 10” is 50lbs. A slab measuring 10” x 10” x 2” is 10lbs. A slab measuring 10” x 10” x 1” is 5lbs.
Q: At what rate can I expect the dry ice to sublimate?
A: Customers will find that with good insulated shipping similar to those styro-shippers which we sell, there will be a loss of 1% per hour.
Q: What type of clientele do you find would require the use of dry ice?
A: There are many types of clients we cater to including:
Laboratories
Universities & Schools
Caterers
Drug manufactures
Hospitals
Specialty food processors
Special effects companies for TV and Film
Baked product producers
Meat processors, shippers etc.
Refineries
Transport companies
Hunters/campers
Metallurgy/cold grinding/de-flashing
Q: what are some benefits to using dry ice?
A: It is an alternative method to heat displacement refrigeration. (i.e. electric refrigerators) It is inexpensive & simple. It consumes no fuel or electricity. It can be cut, wrapped & delivered to predetermined specifications and limiting waste.
