Using Dry Ice
Dry Ice is a YETI’s best Friend
A major benefit of the YETI cooler is its dry ice compatibility. There are a few hints and tricks to using dry ice safely and effectively. When used in your YETI cooler, dry ice can keep food and drinks cold and frozen longer than regular ice.
What is Dry Ice?
Dry Ice is the frozen form of Carbon Dioxide and its -109° F temperature makes it perfect for freezing quickly and keeping items frozen. Dry ice gives off more than twice the cooling power per pound than regular water ice, and this added benefit provides a dramatic weight savings when packing your YETI.
Proper Handling and Safety:
Dry Ice is completely safe to be used alone or combined with regular water ice, but there are handling precautions to keep in mind. Because dry ice is so cold, it must be handled with protective leather or cloth gloves (oven mitts or hand towels also work) to prevent freezer burning. It is also wise to keep dry ice away from small children.
One other safety item to keep in mind is ventilation. Because dry ice is frozen carbon dioxide, when it melts, or sublimates, it gives off carbon dioxide gas. It is not harmful, but without proper ventilation (example: riding in a closed vehicle), it can cause shortness of breath, and in extreme cases, loss of consciousness because the carbon dioxide will displace oxygen. The simple solutions are as follows: store your cooler with dry ice in well-ventilated areas; and make sure there is proper ventilation during transportation.
Putting that Dry Ice to Work:
- Use one 10 inch/10 pound block of Dry Ice per 15 inch length section of your YETI cooler. This will ensure everything is kept frozen, including water ice, for at least 24-48 hours.
- Wrap each block of dry ice in several sheets of newspaper before packing.
- Dry Ice can be packed on top of or below food, but it will keep longer if packed on top (for convenience, many people pack it on bottom).
- When packing the cooler with dry ice, try to minimize air pockets (empty space) in your YETI. Less air space will keep dry ice frozen longer. Water ice can be used to fill this space.
- As with regular ice, try to keep your YETI in the coolest temperature spot available. Covering your cooler with a blanket or sleeping bag will help preserve all ice longer.
- Dry ice can be used in combination with cubed or blocked water ice.
Unfortunately, we have seen the effects a hurricane or a natural disaster can have on our communities. Using your YETI combined with dry ice and regular water ice could dramatically increase the chances of your perishable items enduring the situation.
