All QOOL products are produced in a climate-neutral manner in Würzburg. In addition to the black color, the Eco+ version is made from recycled material, thus underlining our sustainability claim. The performance of the two boxes is no different.

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.

To achieve the maximum temperature retention time of 10 days in the QOOL Box, optimal conditions should be created. It is advisable to fill the box in a similar way to the refrigerator, by filling it as full as possible with chilled products. Ideally, the products should be pre-chilled when placed in the box. The box can also cool down, but this shortens the running time. Depending on use, the Temperature Elements should be recharged or frozen after around 10 days.

The deep frozen elements are mainly recommended for professional use, such as in the catering industry. In order to pre-cool the elements correctly, they must be stored for at least 72 hours at a minimum of -30 °C. Commercial freezers can often only be set to -18 °C and cannot handle these extreme temperatures. When storing, it is also important to ensure that the elements are free-standing and not stacked on top of each other. This is the only way to ensure that the 72 hours are sufficient to completely freeze the elements and prepare them for the desired application.

For deep-freeze applications, we would therefore recommend our standard frozen elements. These give off -20 °C to -10 °C in the QOOL box and keep your refrigerated goods frozen for up to 10 days. The standard frozen elements can also be pre-cooled in standard freezers at -18 °C.

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.

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.

Thanks to specially developed PCM recipes, the QOOL Temperature Elements are suitable for various temperature ranges. All ingredients are harmless and suitable for use with food.

• Standard Frozen (-20 °C to -10 °C) | For transporting all frozen foods and perfect for ice cream.
• Standard Cool (-2 °C to +2 °C) | Particularly suitable for sensitive refrigerated goods such as fresh fish and meat.
• Controlled Fresh (+2 °C to +8 °C) | Suitable for storing fruit, vegetables, dairy products, drinks and temperature-sensitive medicines.

Standard 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 inside of the elements should now be solid. The Temperature Elements are immediately ready for use and can be used with the QOOL Box.

Standard 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. Take the Temperature Elements out of the freezer/chest freezer. The inside of the elements should now be solid. The Temperature Elements are immediately ready for use and can be used with the QOOL Box.

Controlled 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. Take the Temperature Elements out of the freezer/chest freezer. The inside of the elements should now be solid. The Temperature Elements are immediately ready for use and can be used with the QOOL Box.

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.

days on the road.

Which box size is suitable for how many people?

The QOOL Box offers different size options, depending on your needs and number of people:

• QOOL Box M: This variant is ideal for 2-3 people. It has a filling volume of 27 liters (22 liters with Temperature Elements). This volume allows for a food supply for about a week to 10 days. Alternatively, the box offers enough space for up to 16 bottles with a capacity of 0.5 liters.
• QOOL Box L: If you are a group of 4 people or more, we recommend the larger QOOL Box L with a capacity of 43 liters (33 liters with Temperature Elements). This generous size makes it easy to store 24 0.5 liter bottles and offers enough space for drinks and food for a weekend trip with the family.

If the larger temperature elements of the QOOL Box L do not fit in your freezer compartment, we also offer a set of 6 temperature elements in size M. You can find these under accessories.

It is recommended to pack the QOOL Box as fully as possible, as this optimizes the cooling performance and can keep it cool for up to 10 days. Choose the box size according to your needs and the number of people to ensure the best user experience.

The stability of the QOOL Box is impressive. It has been specifically designed for robust and reliable performance and can support an impressive 150 kg of weight. Thanks to its stable construction made of EPP (expanded polypropylene), a material known in the automotive industry as a shock absorber, the box proves its worth in a variety of applications, be it as a seat, table or step. Its durability and reliability make it a versatile companion in a wide variety of situations.

The outer material of the QOOL Box is not made of Styrofoam, but of EPP, expanded polypropylene. EPP is an extremely lightweight, robust and water-repellent material. Its main purpose is to protect our high-performance insulation and also to provide strong insulation performance.

Yes, the QOOL Box is able to keep warm products warm thanks to an innovative technology that is also used in space travel, the global shipping of corona test kits and corona vaccines: the vacuum insulation panels. These panels are built into all sides, the lid and the bottom of the box, creating a kind of "thermos flask in box format".

Thanks to this advanced insulation technology, the QOOL Box can achieve excellent thermal insulation performance. However, it is important to note that the warming process is not supported by additional "heating elements" as is the case with refrigeration. Therefore, the box can keep warm products warm for a few hours to a day, depending on how full the box is (a fuller box will maintain the appropriate temperature longer). The QOOL Box is thus a versatile solution to keep your food both cool and warm, depending on your needs and situation.

Cleaning your QOOL Box is straightforward, as both the specially treated outer shell and the interior are easy to clean and disinfect. However, avoid using harsh chemicals to avoid damaging the material. A sponge dampened with water is ideal for cleaning.
After the cleaning process, we recommend wiping the cool box and temperature elements thoroughly dry and storing them uncovered for a few days. This step helps prevent possible mold growth in the box and ensures that the QOOL box remains fresh and ready for use.

To avoid damage to your QOOL Box, please note the following tips:

• Keep the box away from fire: Do not place the QOOL box near open flames or glowing objects. Embers could cause small holes in the outer material of the box.
• Avoid using sharp objects: Do not cut directly on the surface of the box with sharp objects. This could cause scratches or cuts that could damage the material.

By following these simple guidelines, you can ensure the longevity and functionality of your QOOL Box and avoid possible damage. The box will continue to reliably keep your food cool and accompany you on your adventures.
