 1. Do Xtracool Ice Boxes have internal Ropes ?

Self supporting hinges on Xtracool ice boxes means our ice boxes do not need unsightly and impractical ropes that dangle into the ice box and get in the way.

3.How long will ice last in a Xtracool Ice Box ?

The amount of time ice will last will depend on many factors eg the ice used (block vs party), the ambient temperature etc. Please see our section on this website for information on ice maintenance (CLEANING & ICE MAINTENANCE).

Also you may be interested in the ice test performed on Xtracool 70 Litre Premium and Deluxe boxes. Please be aware that you will see many claims of ice holding capabilities for various ice boxes, however rarely do you see the information provided on how the test was conducted and under what conditions. Xtracool is proud to publish our tests on this website (PERFORMANCE) as we believe we have the best quality ice boxes on the market.

4.Does adding salt to ice keep ice longer ?

The short Answer is yes. Before refrigeration, a mixture of ice, salt and water would be packed around an ice cream tub to lower the temperature below freezing point (as low as -21°C ) to make ice cream.

How does this work? Heat is needed to break the hydrogen bonds that bind the ice together. This heat is drawn from the ice/salt/water solution lowering its temperature.

5.What is the best way to use salt for keeping things cold?

Here is a tip for preparing ice that is very useful.
Water with salt dissolved (brine) has a freezing point below 0 C.

• Check what is the temperature of your freezer.
• Prepare water salt solution with freezing point 5 degrees higher.
• Fill this into your containers, seal and freeze in the freezer. When filling leave some air in the container about 1/5 of volume to avoid blowing it up when freezing.

Then use them for your ice box. Because when the ice in these containers thaws at a temperature below 0 C it will keep your ice box cooler.

Use the following proportions:

• Freezer temp -20
• Brine freezing point: -15
• Salt proportion: 22g for 100ml of water.

• Freezer temp -15
• Brine freezing point: -10
• Salt proportion: 15g for 100ml of water.

• Freezer temp -10
• Brine freezing point: -5
• Salt proportion: 8g for 100ml of water.

7.Esky's, Coolers, Ice Boxes and Chilly Bins - What's what ?

Ice box is a generic name for an insulated box used to keep food or drink cool. Ice boxes are known by various names in different countries. An ice box is called a cooler in the USA whereas chilly bin is the preferred name in New Zealand.

But what about Esky? Wikipedia defines Esky as "an Australian brand of coolers manufactured by Nylex. The name is a reference to the association of Eskimos with cold climates. The term has become a genericised trademark and as such is a colloquial term in Australia for any portable cooler".
