GLACIER Coolers were designed with the most important feature in mind. Keep your contents cold for an extended length of time.
The walls are the most important areas for insulation as the cooler walls have constant contact with the Ice and perhaps even your coolers contents. For this reason all of our coolers have about 1.25 inches of polyurethane foam insulation in our walls and lid. The welded inside liner is mold and mildew resistant for long term ice storage.
Below we have shared some suggestions on how to keep your cooler cold for an extended period of time. We hope the following information will be useful and informative.
A cooler is designed and insulated to retain cold as well as heat in or out of the cooler. For this reason do not start with a cooler that has been sitting outside in the sun or in a hot garage. You will need a lot of ice to cool down a good size cooler that is hot. Try to at least bring the cooler indoors for a couple hours and keep the lid open so that the entire cooler inside and outside can cool down to at least room temperature. Now that your cooler has chilled down it will take much less energy from your ice to cool it down.
The same principle goes with the coolers contents as it does with the cooler itself. If you put hot drinks and or contents in the cooler the ice within the cooler has to now use energy to cool these drinks and contents to the temperature of the ice which is 32 degrees. This alone will melt a significant amount of ice depending on how many items are loaded in the cooler.
Ten pounds of any type of ice (crushed, cubed, solid block, dry ice) will not all produce the same results, but all have their unique purpose in a cooler.
- Crushed ice will last the least in any cooler because of its small size. The benefit of crushed ice is if you have drinks you want to have at its coldest temperature as fast as possible then crushed ice is the way to go because it will be in constant contact all around your beverages.
- Cubed ice (or bagged ice) is the most common ice used in coolers. Cubed is much more effective than crushed ice but does not do the job as well as solid block of ice in keeping the contents of your cooler cold for extended periods of time. Cubed ice will cool the contents of your cooler much faster than a solid block of ice.
- Solid block ice will last much longer than the crushed or cubed ice but will not cool the contents of your cooler as quickly as the crushed or cubed ice. Imagine putting your beverages in your refrigerator at home, this will take a while to cool your drinks in the refrigerator. This is the same principle using a solid block of ice. Solid ice works best in a cooler when it is used with crushed or block ice at the same time.
- Dry ice is the best ice to use to keep your cooler cold or the contents in your cooler frozen for extended periods of time. Dry Ice is particularly useful for freezing, and keeping things frozen because of its very cold temperature: -109.3°F or -78.5°C. Dry Ice also works very well when it is used with crushed or block ice at the same time. With our South Florida and Caribbean hurricanes this is the best option for keeping your freezer items cold for long extended periods of time when the power is out.
Yes, you can use dry ice in any of our coolers. . Dry Ice is particularly useful for freezing, and keeping things frozen because of its very cold temperature: -109.3°F or -78.5°C. Make sure you use precaution using dry ice as dry ice will freeze and keep frozen everything in its cooler. These frozen items will take some extra time to thaw because they have been so cold. Packing an ice chest using dry ice is great for a long trip. When packing with dry ice, follow these simple steps.
- Plan using 10 to 20 lbs of dry ice for every 24-hour period. This varies on the size of the ice chest.
- Place only frozen foods in the cooler until the dry ice is gone. Then place non-frozen goods in a separate ice chest on regular ice
- Place the dry ice on top of the food as cold air sinks and will keep your food items colder.
- Fill any empty space with wadded newspaper or other filler when packing items in the container. Any dead air space will cause the dry ice to sublimate faster.
- Plan on using 5 lbs of dry ice for every 10 quarts of cooler space you have.
- Do not wrap dry ice in a plastic bag. The gas from the dry ice will make it explode.
Opening your cooler lets the cold air out of your cooler which is then replaced with the warm outside temperature air. Now your ice has to cool down the warm air inside your cooler. When you open your refrigerator at home all the cold air escapes and when you close the refrigerator the compressor turns on again to try and cool the inside of the refrigerator again. This is the same with your cooler; the less you open the cooler the better it is for your ice within the cooler.
Keeping your cooler in direct sunlight will warm the outside of the cooler. Doing this the ice in the cooler has to cool the cooler down. With the amount of insulation in our coolers this does not happen very rapidly but over an extended period of time it will make a difference. Try to keep your cooler in the shade under a tree or on a covered patio.
This is a very good question. We recommend keeping the water in the cooler. If you have drinks in your cooler that you want at its coldest temperature, then your best bet is to keep the water in the cooler. This allows more surface contact with the drinks in the cooler to keep you contents at their coldest. We believe if you let the water out of the cooler, the warm outside air has to enter the cooler. At that time the ice needs to cool the warm air inside the cooler. As a result this will end up melting more of the ice more rapidly.
When packing your cooler try to keep your cooler packed with all your beverages and items to keep cold, then fill the rest with ice. Do not put meats on the bottom of the cooler as when the ice starts to melt you do not want your meat in the water. If you have excess air space in your cooler, try and fill the air space with newspaper. This does a very good job.
Try and use a cooler size that will fit the purpose it is being used for. If you have two people going on a picnic you do not want to use a 160 quart cooler. You will never be able to fill it up this cooler and you will have a huge amount of excess space in the cooler. A large cooler is great for holding large amounts of items that you want to keep cold. For this reason, we have many customers purchase more than one cooler for different purposes.
We at GLACIER believe a clean cooler is a happy cooler, and you (the customer) will enjoy our coolers much more when they are clean and ready for use. We recommend just using soap and water to wash of the coolers after each use. Every once in a while we sanitize our coolers with the use of a small amount of bleach and water to clean any bacteria that might be growing on the coolers from the heat. You may even use a pressure cleaner on any of our coolers.
