Last year, an anxious phone call was taken from a freight forwarder over the Christmas period by TOWER. A KryoTrans KT70 had been configured at 2-8°C and was being held by customs
The forwarder’s agent noted from the KryoLogger’s external display that the load was warming up and showing +7°C on the display: anxious that the unit was going to fail he asked our advice. He was told to place the whole unit in a refrigerator where it could remain indefinitely until the custom issues had been overcome.
We were was somewhat startled when, two days later, we had another call from the same gentleman saying the load temperature was now down to 3°C. We asked what temperature the fridge was set at, after he went away to check and announced “It is below -20°C!” “OK”, we said, “please take it from the FREEZER and let it sit in the ambient temperature.”
The unit was eventfully cleared and delivered to a very grateful customer, whose goods had stayed in compliance for 10 days even though the recorded ambient temperature trace was far from straight and the KryoLogger’s display and alarms had been used to full effect.
