The QOOL Box achieves its outstanding thermal insulation performance through an insulation technology that is also used in space travel: vacuum insulation panels that are installed on all sides of the box, in the lid and also in the base. A large "thermos flask" in box format, so to speak. Really durable: when used correctly, the QOOL boxes can have a lifespan of up to 50 years.

Our QOOL Temperature Elements consist of a particularly robust plastic casing that is filled with so-called Phase Change Material (PCM) and then sealed. The dimensions of the QOOL Temperature Elements are perfectly tailored to use in the QOOL Box. Thanks to specially developed PCM recipes, the QOOL Temperature Elements are suitable for different temperatures. Perfect for different areas of application and individual needs. All ingredients are harmless and suitable for use with food.

For optimal cold and heat retention, the lid and body are tightly sealed with the QOOL Air Seal. Special openings are provided at the corners for opening the QOOL box. Caution: Always close the lid securely and press firmly on all sides to maintain the desired temperature range for as long as possible.

QOOL Shock Absorber technology is based on a specially developed, resilient, shock-absorbing material comparable to the foam found in fascia rollers or the cushioning soles of running shoes. This material forms the outer shell of the QOOL cooler and provides excellent shock absorption and additional insulation.
