How to use a
HEFTI Ice Box for best
Ice Retention
- Pre-cooling your cooler
- Fill your cooler to capacity
- Pre-chill your items
Pre-cooling is a great way to improve ice retention. By lowering the initial temperature of the cooler, you can help slow down the melting of ice and keep your contents colder for longer. For best performance, always store your cooler in a cool or shaded location, or even a refrigerator for 24 hours prior to use. You can also use ice packs or frozen water bottles.
We recommend using at least twice the amount of ice as the contents. The less empty space there is in your cooler, the longer your ice will last. If there are gaps, fill them with ice packs, frozen water bottles, or even crumpled newspaper to help insulate the cooler. (Remember, cold air travels down, so if you want your beverages well chilled, load cans and bottles first, then cover with ice to the top).
If possible, refrigerate or freeze the items you plan to store in the cooler before packing them. Cold items will help maintain the temperature inside the cooler and reduce the amount of heat transferred to the ice.
- Use ice that is already frozen solid
- Keep away from heat and direct sunlight
- Consider using dry ice
Ensure that your ice is completely frozen before placing it in the cooler. Partially melted or slushy ice will melt faster and won’t retain cold temperatures as effectively.
Heat is the enemy of ice retention because it causes the ice to melt faster. When the cooler is exposed to direct sunlight or high temperatures, the heat transfers into the cooler and accelerates the melting process.
Tips to reduce heat transfer:
- Do not store coolers in hot locations.
- Bring the cooler inside at least 24 hours before use.
- Do not place the cooler directly in the sun or on a hot surface as this will melt the ice in the bottom of the cooler. For example, place a towel beneath the cooler if placing the cooler on a hot surface like the back of a bakkie, on the top of a car, or on the floor of your boat.
- Cover the cooler with a towel when in direct sunlight.
Dry ice, which is frozen carbon dioxide, can provide extremely cold temperatures and prolonged ice retention. However, it’s important to handle dry ice with caution.
- Don’t drain cold water
- Minimise opening the cooler
- Protect perishable foods
Melted ice water has better thermal conductivity than air, so having ice water in the cooler can help maintain lower temperatures and improve ice retention. If the cooler does need to be drained, replace the open-air space with towels or newspaper if you are unable to refill it with more ice
Every time you open the cooler, warm air enters, and cold air escapes. This can significantly increase ice melt. Close lid quickly after opening. Do not leave the lid open longer than necessary.
Pack food in sealed containers to help keep food dry. Place perishable foods like meat and dairy products directly on the ice.
