A temperature range that only QOOL masters
Freezing without compromise: The QOOL Frozen Temperature Elements maintain a stable temperature between -20°C and -10°C – completely without electricity. Ideal for frozen products such as meat, fish, raw food, or ice cream. Developed and manufactured in Germany – for maximum safety and consistent performance, even over long transport times.
Only in combination with our QOOL Box does the performance remain so long and consistent.

Frequently Asked Questions
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.
The QOOL box achieves its impressive thermal insulation performance through the use of vacuum insulation panels that are installed on all sides, in the lid and in the base of the box. In combination with the QOOL Temperature Elements, the temperature inside can be kept constant for several days. The box can be opened several times without any problem, as long as the lid is closed in such a way that no air exchange takes place.
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.
As an alternative to the QOOL Box L, we offer a set of 6 small elements that were originally intended for the QOOL Box M.
By correctly placing the temperature elements, you can maximize the cooling performance of the QOOL Box and keep your food optimally fresh, whether you are away for a few days or up to 10 days.
