The Thermobox temperatur test

A special test method provides clarity about the thermal box temperature in cold and hot operating conditions. Cold and hot: the KÄNGABOX® Professional Fresh Blue PR3217FB is put to the test in both temperature ranges.

Test method according to DIN EN 12571

A transport unit for food has to meet certain requirements. The test is conducted in a climatic chamber, in which a constant ambient temperature of 25° C prevails. The measurement starts after the water in the feed tanks has reached a defined starting temperature. The test time lasts three hours. If the temperatures remain within the specified limits, the test is passed. The specifications apply to local and short-term transport of consumption-ready food. In this temperature range, risks of hygienic and toxic nature as well as quality losses are the lowest.

The climatic chamber

Climatic chamber

The climatic chamber ensures a constantd ambient temperature of 25 °C during the test procedure.

Senosors are connected to the box

Several thermal elements are connected with the temperature meter. The sensors are located outside, inside on the bottom, on the side and in the middle of the container.

Hot stays hot

And indeed hotter than the European norm requires. Compared to the specifications in DIN EN 12571, a 41 % better result can be achieved. According to the DIN rules, the contents of the transport unit with an initial temperature of 75 °C may not fall below a temperature of 65 °C after a test duration of three hours. This means a maximum temperature decrease of 10 K. The KÄNGAOBOX® passes the test with a temperature of + 68.9 °C. This means a difference of 6.1 K and an average temperature decrease of 2 K per hour.

Cold stays cold

And indeed colder than the European standard requires. An even 42 % better result than required in DIN EN 12571 can be shown in this test. According to the DIN rules, the contents of the transport unit must not exceed a temperature of 7 °C after a test duration of three hours. The initial temperature is 3 °C during this test. This means a maximum temperature increase of 4 K. The KÄNGABOX® ended the test with a temperature of + 5.3 °C. This means a difference of 2.3 K and an average temperature increase of 0.8 K per hour.

Conclusion

As a result, the KÄNGABOX® PR3217 exceeds the requirements for thermal reaction in both the hot and the cold ranges and proves that is has good insulating properties. This is thanks to the EPP material and the special workmanship of KÄNGABOX®. The high material density of 60 grams per liter and the special design of KÄNGABOX® FreshBlue Professional really pay off in terms of quality.
