TransFresh controlled atmosphere (CA) shipments involve the installation of an electronic controller into a purpose built compartment (Security Enclosure or SE) on the container reefer unit by TransFresh representatives at the port of origin. At the end of each voyage the controller must be removed and returned to TransFresh for service and reuse in future CA shipments.

TransFresh requests that at the earliest time after the voyage is completed each controller be:

  • removed from the container (instructions)
  • returned to TransFresh by FedEx (instructions)
  • please send ALL controllers back IMMEDIATELY after they are removed.
Please Note
  • When TransFresh controllers are removed from their compartment it is necessary to replace them with a special foam block. "Controller retrieval kits" are supplied by TransFresh and consist of a special transport carton which has the foam blocks and return address labels inside. Please notify TransFresh if you require retrieval kits - please provide full delivery address and phone number and we will ship to you immediately.
  • TransFresh will endeavor to notify destination contacts in advance of the arrival of each shipment, but for various reasons containers may be found with controllers in them. If a controller is found in an empty container, a container carrying frozen cargo or a container with the air exchange vents open then it is no longer in use and should be removed immediately. If you have any doubts or questions about any container, please contact us.
  • For some cargoes there will be fans and cables left in the container. Click here for further information on fans and cables.

Controller Removal Instructions

To remove a controller you will need the following tools:
  • Wire cutter
  • Slot screwdriver
  • Ladder
  • Retrieval parcel with foam block (Provided by TransFresh)
Follow these steps:
  1. The Refrigeration unit must be turned off during the removal process. Unplugging the controller with power on can cause blown circuits and/or data loss.
  2. Cut wire seal on TransFresh Security Enclosure.
  3. Undo the 2 screws on the bottom of the TransFresh door and open cover.
  4. Undo the 2 screws that fasten controller in place.
  5. Grip the controller by the handle in the middle, front and gently pull it out of the Security Enclosure.
  6. Insert the white insulating foam block from the retrieval kit where the controller was housed.
  7. Close the TransFresh Security Enclosure door and fasten the 2 screws until firmly closed.
  8. If the reefer is still laden, open the refrigeration unit air exchange to approximately 25% and ensure the reefer is left running.

Important Note: There is only one way that the foam block will fit. Please do not force it as damage may occur. The foam block is vital for the proper operation of the refrigeration unit.

DO NOT OPERATE THE REFRIGERATION UNIT WITHOUT A FOAM BLOCK IN PLACE!
