1. What is a Twozone and what does it do?

Your Twozone not only increases the capacity of your fridge/freezer by 20 to 40 litres, it also gives you the flexibility of 2 cooling zones.

Use your fridge/freezer as a freezer and your Twozone becomes your refrigerator/chiller for all your drinks, fruit etc, or use your fridge/freezer as your refrigerator and then your Twozone becomes your chiller/crisper for salads, cheeses, butter etc.

The choice is yours...

  1. Will my fridge work harder?

No, but it will run a little longer due to the increased capacity. When it first starts up it will take longer to cool down but once it reaches the temperature that you have set, it will only increase your power consumption by less than 10%. See Independent Laboratory Test Results

Cold air is dense so it sinks. Once your fridge/freezer reaches the temperature that you have set, the fridge turns itself off. It doesn't try to pull the Twozone down to the same temperature, therefore it doesn't over load or over work you fridge/freezer.

  1. The Twozone is a simple plastic box. Why is it so expensive?

Twozone is made from heavy duty polyethylene plastic and filled with high density refrigeration foam, both products of which are relatively expensive.

Its strength and durability are second to none. Drop it and it will not shatter. Hit it with a hammer and it will make just a small indentation.

Support your car on it and it will not lose much of its shape. (Not recommended but see photo to right).

Twozone is not just another plastic icebox which is relatively cheap but also very fragile.

Twozone is manufactured to withstand the toughest conditions you are likely to experience.

  1. What is the best way to use my Twozone?

Using your Twozone with your fridge set to ‘chill’

  1. Store your perishables in the Twozone.
    2. Store your drinks in the fridge.

    Using your Twozone with your fridge set to ‘freeze

    3. Store your drinks in the base of the Twozone.
    4. Store your perishables on top of the drinks in the Twozone.
    5. Store your frozen goods in the fridge.

The Twozone Refrigerator Compartment allows you to set your fridge/freezer to a 'deep freeze' or 'cold drinks' temperature in the bottom section. Anything that you don't want to freeze should be placed in the Twozone top section.

Twozone creates the perfect temperature in the top compartment. This makes it ideal for fruit, vegetables, dairy products and other perishables.

Handy Hint: To use Twozone for keeping salads and perishables fresh and chilled when your fridge/freezer is set to freeze and you have no drinks to form a buffer, place a barrier (tea towel or cardboard) between the fridge/freezer and the Twozone. This will slow the temperature transfer and help reduce the likelihood that your perishables will freeze.

  1. At what temperature should I keep my fruit and veges?

All food has a limited shelf life this will vary depending on the type of food and how it is stored prior to purchasing it and after you purchase the food. One of the critical factors when storing your Fruit and Vegetables in a refrigerator is the inability to control the relative humidity. Most fruit and vegetables unless stored at high relative humidity i.e.90 to 99% will suffer from water loss which results in Chill Damage and Freezing. The best way to combat this effect is to store these fruit and vegetables at slightly higher temperatures in your portable refrigerator.

Below are some examples of what sort of life you can expect from your fruit and vegetables at these temperatures.

  • Cucumber - 10-14°C will store for up to 10 days. Chill injury starts to occur at 10°C and below
  • Tomatoes - Firm Mature 12-18°C, Firm Ripe 6-10°C, Store at 8°C for only 3 days, Store at 14°C for up to 13 days. Chill injury starts to occur at 12°C and below
  • Cauliflower - 12°C will store for up to 10 days
  • Cabbage - 12°C will store for up to 14 days
  • Lettuce - 5°C to 11°C will store for up to 7 days
  • Capsicum – 7°C to 10°C will store for up to 18 days
  • Banana – 13°C to 15°C will store for up to 10 days. Chill injury starts to occur at 10°C and below
  • Peaches/Nectarines – 10°C to 20°C will store for up to 20 days. Chill injury starts to occur at 7°C and below

Note: The above table is a guide only as you do not know how long the produce has been
stored prior to retail sale.
