How does the cooler work?
Our cooling technology cannot be compared to other cool boxes. If you combine the QOOL Box with the QOOL Temperature Elements, the temperature inside can be kept constant for many days - without a power supply, in any climate zone, all over the world.

The QOOL Box achieves its outstanding thermal insulation performance through vacuum insulation panels that are installed on all sides of the box, in the lid and also in the base.

The QOOL Temperature Elements contain so-called phase change material and can absorb or release energy at a certain temperature.

If you combine the QOOL Box with the QOOL Temperature Elements, the temperature inside can be kept constant for many days.
