Advantages

High-tech instead of ice pack
QOOL Temperature Elements store large amounts of energy and maintain precisely defined temperatures – over several days and without electricity.

Durable and resource-saving
Designed for long-term use. Reusable, maintenance-free, and made in Germany.

Precise and efficient
The elements are precisely tailored to the QOOL boxes. This optimizes the available space and ensures stable temperatures throughout the interior.

Frozen (-20°C to -10°C): Please freeze the Temperature Elements in a freezer/chest freezer at a temperature of at least -18°C for at least 72 hours. Remove the Temperature Elements from the freezer/chest freezer. The interior of the elements should now be solid. The Temperature Elements are immediately ready for use and can be used with the QOOL Box.
Cool (-2°C to +2°C): Please freeze the Temperature Elements in a freezer/chest freezer at a temperature of at least -18°C for at least 12 hours. Remove the Temperature Elements from the freezer/chest freezer. The interior of the elements should now be solid. The Temperature Elements are immediately ready for use and can be used with the QOOL Box.
Fresh (+2°C to +8°C): Please freeze the Temperature Elements in a freezer/chest freezer at a temperature of at least -18°C for at least 8 hours. Remove the Temperature Elements from the freezer/chest freezer. The interior of the elements should now be solid. The Temperature Elements are immediately ready for use and can be used with the QOOL Box.
Our Temperature Elements are 100% tested. If they don't freeze, it's often due to the temperature in the freezer compartment – we recommend a minimum of -18°C for Frozen Elements. Tests have shown that many household freezers are sometimes only set to -16°C or warmer, even if they appear colder.
Ideally, the elements should also have enough space to allow the cold air to circulate freely. If they're too close together, the pre-cooling time will be longer. It's best to place the elements in the bottom, coldest compartment of the freezer. This will ensure they freeze through!
If these points are met and you're still unsure, don't hesitate to contact our customer support . This way, we can help you quickly and avoid unnecessary effort and costs.
- For the QOOL Box M, which can cool for up to 10 days without electricity, we recommend the maximum configuration with 4 temperature elements of the same size (1 liter). Place one element upright on the sides of the handles and place the other two elements on top of the food. The two top elements have the greatest effect, as cold air sinks downwards and flows through all the refrigerated goods. If you are only away for 3-5 days, 2 of the 4 temperature elements are sufficient. These can then be conveniently placed on the side, but should be placed on top of the refrigerated goods for optimal cooling.
- For the QOOL Box L, which can cool for up to 10 days without electricity, a surround system (cooling cube) with 6 temperature elements is recommended. There are 2 different element parts: 2 square elements (for the base and lid) and 4 side elements. Place one of the large elements on the base of the box. Then add the 4 side elements with the straight side facing the respective wall. Finally, simply place the lid on top. Here, too, not all elements are necessary for 3-5 days.
In combination with our Temperature Elements, the QOOL cool box enables the precise setting of specific temperature ranges such as the refrigerator range from +2 °C to +8 °C or the freezer range from -20 °C to -10 °C. We can keep these temperature ranges constant for up to 10 days.
Compared to standard ice packs, which are often filled with water, our Temperature Elements offer improved performance. Conventional ice packs give off a temperature of around 0 °C when defrosting, which is already too cold for some applications and foods. However, our Temperature Elements are able to maintain the required temperatures and thus enable longer cooling of up to 10 days without electricity. Depending on the needs and requirements of the cool box, other ice packs can also be used in the box.
The same applies to ice cubes, as they are also made of water and are around 0 °C when thawed. As the QOOL Box was specially designed for use with Temperature Elements, it does not have a drain for meltwater. If ice cubes are used for cooling, we therefore recommend using a bag or similar container to collect the meltwater.
To achieve the maximum temperature retention time of 10 days in the QOOL Box, optimal conditions must be created. It is advisable to fill the box similarly to a refrigerator, filling it as full as possible with chilled products. Ideally, the products should be pre-chilled when placed in the box. While the box can also cool down, this will shorten the operating time. Depending on use, the Temperature Elements should be recharged or frozen after approximately 10 days.
The QOOL Box can also be used without Temperature Elements. If the QOOL Box is filled with chilled drinks or food, the refrigerated goods will stay at the right temperature for 1-2 days. If a specific temperature range (refrigerator or freezer) is required, we would recommend our Temperature Elements. The Temperature Elements also extend the storage time to one week to 10 days.
