The "Thermal Customer Support Team" performs extensive performance tests at constant +30°C, 0°C, +50°C and -20°C to prove that our containers protect your products reliably from extreme outside temperatures at all times. All tests are performed in worst-case scenarios with no payload inside of the container.

If a container were qualified including goods, a preconditioned thermal mass would be loaded into the container and this could improve the test results. As the loaded thermal mass varies per shipment, we test without any content. In a real shipment the container will always be loaded with goods which prolongs the container performance.

If a high outside temperature is followed by a low outside temperature the inside temperature will increase with a time delay of six hours and then decrease again. In other words, combined temperature cycles will prolong the container performance due to the properties of the phase change material applied. We call this the self-recovery effect Our standard qualification reports do not use the self-recovery effect as it would increase the performance duration.

Together with our "Thermal Customer Support Team", we are able to produce simulations using transport temperature data provided by the customer to calculate the container performance according to the needs of the customer. We are also able to provide you with live shipment data for specific lanes and specific temperature ranges which prove that the va-Q-tainer performs much longer than 120 hours with payload and in fluctuating temperature environments.

To avoid losses in time and resources when switching to va-Q-tec's advanced passive container solution, va-Q-tec has compiled the TTP which provides important documents such as MSDS, container qualification reports, FMEA, SOPs, data logger specifications, customs information, etc.
