  • Page 4: Introduction

    The Container The RKN t2 container is a temperature controlled air cargo container used to transport temperature sensitive cargo in the refrigerated, do not freeze (2-25°C / 36-77°F) and deep frozen product temperature ranges. In general, the product temperature to be maintained must be less than the ambient temperature.
  • Page 5 The container uses one fan for air distribution. The RKN t2 is a fork liftable LD-3 air cargo container designed to hold one US-pallet 1220 x 1016 mm (48 x 40") or one EURO-pallet 1200 x 800 mm (47,3 x 31,5") of cargo...

  • Page 6: Limits, Ambient Conditions

    LIMITS, AMBIENT CONDITIONS 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...

  • Page 7: Preconditioning

    Cargo temperature recording If records must be kept of cargo temperature, Envirotainer strongly recommends that temperature recorders are placed inside cargo boxes in accordance with industrial guidelines. The temperature displayed on the control unit is the temperature of the air at the sensor in the container and will fluctuate more than the temperature of the product.
  • Page 8 PRECONDITIONING Precondition with dry ice (for deep frozen cargo) An amount of dry ice required to pre-condition the container is placed in the dry ice bunker and in the cargo space to accelerate the preconditioning process. 1) Calculate the total amount of dry ice required for preconditioning and shipment. Refer to sections "Dry ice calculation"...

    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 Loading - General Guidelines Observe the following general guidelines when loading the container: 1) Use the door straps (Figure 2) to hold the doors open when loading. 2) Load the cargo on a pallet or on spacers at least 2 cm high to allow a proper airflow. 3) Do not load cargo between the spacers on the container walls.
  • Page 11 CARGO / DRY ICE LOADING Cargo Loading - Refrigerated / Do Not Freeze 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. 2) Load the container.
  • Page 12 CARGO / DRY ICE LOADING Cargo Loading - Frozen For shipments with frozen cargo dry ice is placed in the cargo space. This keeps the 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 Container loading takes place 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 ice bunker and cargo space of 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.

    2) Remove and dispose of any remaining dry ice. If local regulations allow it, the dry ice may be placed outdoors. It will dissolve quickly. Storage It is recommended that the RKN t2 container be stored on flat ground. The storage temperature should be between -40°C (-40°F) and +50°C (+122°F). Important! No container, cargo or other must be stored on top of a RKN t2.

  • Page 23: 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 24 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 and across to the left 5) The amount of dry ice for preconditioning the container is 13 kg...
  • Page 25 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 26 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.
