The versatility of the QOOL Box is also shown in my catering service. From the purchase of the food to the use of the prepared food, everything was perfectly cooled. This is especially essential in areas where the cold chain has to be maintained. Even the increased opening did not matter and so after three days of catering service the temperature in the QOOL box had only risen by 1 °C. What luck, because a warm Panna Cotta would certainly not have tasted good on the third day.
