Dry ice

Dry ice is solid carbon dioxide that provides an efficient and clean way to cool, preserve, and clean. It is suitable for a wide range of applications, from cooling food products and metals to dry ice blasting and creating impressive special effects.

Manufacture and sale of dry ice

Woikoski produces dry ice at its carbon dioxide plant in Kokkola, from where it is delivered to the whole of Finland. Woikoski produces dry ice for industry and the food industry in accordance with the FSSC 22000 food certification.

The dry ice is sold in granules or chunks. Pack sizes are 10-360 kg in granules and 15-500 kg in chunks. Dry ice is supplied in disposable styrofoam containers (10 kg granules/15 kg chunks), larger quantities are supplied in rental boxes.

Due to its characteristics, the product evaporates 5-10 % of its weight/day.

Dry ice is extremely cold ice with a temperature of -78.5ºC. It is made from liquid carbon dioxide, which is solidified into snow and compressed into dry ice. Dry ice is odourless, tasteless, non-toxic and non-flammable. When it melts, it does not turn into a liquid but evaporates directly into a gas – a phenomenon known as sublimation.

Dry ice creates impressive effects and is suitable for a wide range of applications. Because it is extremely cold, it is important to follow safety instructions and handle it with care.

Protect Your Hands and Skin

Never touch dry ice with bare hands. Always wear thick, insulated gloves designed for protection against cold temperatures. Safety goggles are also recommended for prolonged handling.
Dry ice can cause severe cold burns (frostbite) to the skin.
If a cold burn occurs: Cover the affected area with a clean, dry dressing and seek medical attention immediately.

Do Not Put Dry Ice in Your Mouth or Drink

Dry ice must never be eaten or placed in the mouth. It must not be added to beverages in a way that could allow pieces of dry ice to enter the mouth or be swallowed.
Even a small piece of dry ice can cause serious cold burns to the mouth, throat, and digestive tract.
If dry ice enters the mouth or is swallowed: Seek immediate medical attention or call the emergency number 112.

Use Dry Ice Only in Well-Ventilated Areas

Dry ice gradually turns into carbon dioxide gas (CO₂). The gas can accumulate, especially in low-lying or poorly ventilated areas such as basements.
Ensure good ventilation and keep children and pets away from dry ice.
Excessive carbon dioxide levels may cause symptoms such as headache, dizziness, fatigue, or nausea.
If someone feels unwell or you suspect carbon dioxide exposure: Move the person to fresh air immediately. Call 112 if necessary and seek medical attention.

Store Dry Ice Only in Its Intended Container

Store dry ice in a container designed for dry ice storage. Never place dry ice in an airtight package or container. As dry ice sublimates, the resulting gas increases pressure, which can cause the container to rupture and create a hazardous situation.

Dispose of Dry Ice Safely

Allow unused dry ice to sublimate in a well-ventilated area out of reach of children and pets.
Do not dispose of dry ice in a drain, toilet, or enclosed space.

Read the Safety Data Sheet

Read the Safety Data Sheet before using dry ice and always follow the instructions provided.

Arrangements – In industry, dry ice is used, among other things, for rapid temperature changes in the joining of different materials.

Dry ice blasting is used alongside soda and sand blasting. Compared to sandblasting, dry ice blasting is a gentler, but at the same time efficient and very clean method of working. The dry ice is converted into a gaseous state during the blowing process and therefore does not cause post-cleaning costs. The advantages of dry ice blasting include a disinfecting effect, removing dirt from the surface without damaging the surface, removing graffiti, mould, ink, paint, glue, resin, stubborn stains, odours and soot. Dry ice can also be used to clean electric motors and cabinets, sensors and glass surfaces.

Cooling (Food additive E290) Dry ice is used in the process industry for refrigeration, catering refrigeration and for transporting samples in laboratories. In the food industry and healthcare, dry ice is a natural part of the cold chain. A variety of food products and samples are transported packaged in dry ice.

Households use dry ice for refrigeration, food storage and event effects.

Orders must be placed at least two working days before the desired delivery date by 12 noon. Delivery will be made by Post. If you need dry ice for the weekend, order delivery for Friday. When ordering, please note that due to the characteristics of the product, it will evaporate 5-10% of its weight/day.

Dry ice orders are paid by invoice after delivery, so you will need to have customer details set up in our system.

Dry ice – Frequently asked questions

Many people are surprised to learn that the white cloud created by dry ice is not actually smoke.

When extremely cold carbon dioxide sublimates into the surrounding air, it cools the moisture in the air so rapidly that the moisture condenses into visible fog made up of tiny water droplets. This is why dry ice creates such impressive visual effects, even though the visible cloud is actually water vapor containing carbon dioxide.

Yes, dry ice can be used to cool bottles and cans. However, dry ice must never be placed directly into a drink.

How to use dry ice safely for cooling beverages:

Place the dry ice at the bottom of the container.
Cover the dry ice with sturdy cardboard or another suitable insulating layer.
Cover the insulating layer with regular ice cubes. The dry ice will help keep the regular ice cold for longer.
Place bottles and cans on top of the regular ice.

A dramatic fog effect is created by adding dry ice to warm water. In general, the warmer the water, the more fog is produced. The fog stays close to the ground and spreads beautifully across floors, tables, and other surfaces.

How to create a fog effect safely:

Choose a suitable container. Use a sturdy, open container that can withstand temperature changes. Do not use glass containers or sealed, airtight containers.
Add warm water. Use warm, but not boiling, water. Leave enough space in the container to prevent splashing when dry ice is added.
Add the dry ice carefully. Use insulated protective gloves and tongs designed for handling dry ice. Add the dry ice in small amounts to avoid splashing. The fog will begin to form immediately.
Allow the fog to spread. The fog will flow over the edges of the container and spread across nearby surfaces. As the water cools, fog production will decrease. If needed, carefully add more warm water.
