Page 7: Limits, Ambient Conditions
LIMITS, AMBIENT CONDITIONS LIMITS, AMBIENT CONDITIONS Specified Limits The RKN and RAP containers are designed to maintain cargo temperatures in a range from -20°C to +20°C (-4°F to +68°F) provided the ambient temperature is 5°C to 25°C (9°F to 45°F) higher than the set temperature. -
Page 8: Preconditioning
PRECONDITIONING PRECONDITIONING The cargo and container must be pre-conditioned to the set temperature prior to loading. Improper precondition will affect the container's ability to maintain cargo temperature. Cargo Preconditioning The cargo must be preconditioned in a temperature-controlled room to the container's set temperature prior to loading (separating the cargo aids the preconditioning process). -
Page 9: Cargo / Dry Ice Loading
CARGO / DRY ICE LOADING CARGO / DRY ICE LOADING Dry ice Dry ice shall be used wrapped or unwrapped as stated in the dry ice tables. Wrapped dry ice • Dry ice in paper/plastic bags. Note that the paper/plastic bag shall not be removed when wrapped dry ice is used. - Page 10 CARGO / DRY ICE LOADING Cargo Temperature Recording The temperature indicated on the control unit is not the product temperature but the temperature of the air inside the container. When cargo temperature monitors are used, they must be placed in or among the cargo boxes (temperature monitors placed outside the cargo does not measure the product temperature).
- Page 11 CARGO / DRY ICE LOADING Cargo Loading - Refrigerated / Controlled Room Temperature When the container is preconditioned with a temperature-controlled room Container loading takes place in the temperature-controlled room used for preconditioning. 1) Ensure that the container is preconditioned to the required cargo temperature. page 10 2) Load the container.
- Page 12 CARGO / DRY ICE LOADING Cargo Loading - Frozen By placing dry ice in the cargo area, the container keeps cargo frozen when ambient temperatures exceed the specified temperature limits, however a lower temperature limit can not be controlled. When the container is preconditioned with a temperature controlled room The container should be loaded in the temperature-controlled room used for preconditioning.
- Page 13 CARGO / DRY ICE LOADING When the container is preconditioned with dry ice Dry ice is in the container prior to cargo loading which takes place at warehouse or ambient conditions. 1) Ensure product and all packing material is preconditioned for at least one week prior to loading.

Page 14: Container Handling Guidelines
HANDLING AND TRANSPORT CONTAINER HANDLING GUIDELINES General Guidelines Observe the following guidelines when handling the container: 1) RKN containers can be forklifted when empty or loaded. 2) RAP containers can be forklifted only when empty; the use of slave pallets is recommended. 3) Use the straps outside the corners of the container to handle the container on roller beds. -

Page 20: Dry Ice Calculation
Calculate Dry Ice Amount for Container Preconditioning Only authorized persons should perform dry ice calculations. It is strongly recommended to have Envirotainer perform the calculation. To calculate the amount of dry ice needed to precondition the container: 1) Note the container temperature (in Celsius) prior to preconditioning. Although using the actual container temperature is preferred, an estimate based on the ambient temperature is acceptable. - Page 21 DRY ICE CALCULATION Calculation Example - Dry Ice Preconditioning An RKN container needs preconditioning with dry ice before loading cargo that has a 5°C temperature requirement. The current ambient temperature is 25°C. 1) The container temperature is 25°C 2) The set temperature is 5°C 3) Container Temp - Set Temp = 20°C 4) Read up from 20°C to the line for RKN and across to the left...
- Page 22 11)If the required amount of dry ice exceeds the bunker capacity, plan to re-ice the container Many variables, such as weather conditions, delays and handling, are beyond control. Envirotainer makes no guarantee that the amount of dry ice indicated in the tables is correct for any specific shipment.
- Page 23 DRY ICE CALCULATION Calculation Example - Container Shipment To calculate the amount of dry ice needed in a container, imagine that we have RKN container with a 5°C temperature requirement with the transportation schedule noted below. Also assume dry ice is used to precondition the container.
