LIMITS, AMBIENT CONDITIONS
The RKN t2 container is designed to maintain the temperature of the cargo shipped in a range
from -20°C (-4°F) to +20°C (+68°F) provided the ambient temperature is 5°C (9°F) to 25°C (45°F)
higher than the set temperature. The following conditions must apply for the container to work
properly:
Pre-conditioning of Cargo
The container does not have battery capacity to cool down or heat up a large quantity of cargo.
The container is designed to maintain the temperature of the cargo. It is therefore very important
that the cargo is pre-conditioned correctly.
Maximum Operating Time without Changing Batteries
The maximum operating time for the container without changing the batteries is 72 hours. If the
container is operated outside the specified temperature limits, the fan may operate continously
which reduces the maximum operating time before batteries must be changed. An example of this
case is deep frozen cargo where it is recommended to change the batteries every 24 hours.
Exposure to Extreme Heat; 25°C (45°F) Above the Set Temperature
Avoid exposure to extreme heat or direct sunshine as it increases the dry ice consumption rate.
Exposure to temperatures 25°C (45°F) above the set temperature should be limited. Take into
account exposure to such conditions when calculating the required amount of dry ice.
Exposure to Temperatures Near or Below the Set Temperature
Since the container does not heat, exposure to temperatures near or below the set temperature
must be avoided. The container must be stored in an environment where temperatures are at least
5°C (9°F) higher than the container set temperature (not applicable to deep frozen cargo).
Exposure to temperatures near or below the set temperatures should be limited.
