Temperature Controlled Service

The dedicated reefer specialists at NAUKA will ensure that your cargo is shipped with the tightest temperature control possible from point of origin to point of destination. Even the most delicate goods are kept in excellent condition in reefer containers.


All exporters should ensure that they have a documented method for maintaining and transporting fresh product in reefer containers. As a result, this paper is based on Nauka Line's procedures, with the goal of informing Nauka Line employees, NAUKA Depots, Exporters, and Packing Sheds, as well as assisting a common understanding of the many components / acts that make up an integrated "cold chain." The ultimate goal for a fresh produce exporter is for their product to arrive in first-class condition. As a result, the customer is satisfied with his or her purchase and may safely sell the product at a profit, generating further business for all parties involved. Consequently, maintaining the cold chain from harvest to delivery to the customer is critical and in everyone's best interests.


We will not seek to add to the body of knowledge on produce harvesting and post-harvest treatment of products; thus, it is believed that all relevant steps / processes have been performed to ensure the product is in "peak condition" when placed into the container. The following are some exporter / packings shed recommended Do's & Don'ts to apply during the pre-shipment process.

1.Exporter should ensure the NAUKALINES agents are aware of the following details and the details should be provided in the booking format given:

• Name of shipper • Size & Type of reefer

• Quantity • Cargo type to be loaded

• Temp. setting required in °F & ° C • Vent setting required

• Pick up date and time • Port of delivery and final port of delivery

• Required date at port of delivery • If IMCO, all necessary details


Any Other Remarks

* The exporter instructs his transportation contractor to collect the container from the designated collection depot and ensure that the truck driver inspects the container internally to ensure that it is clean, odour-free, and undamaged, and that the pre-trip decal (affixed to the machine casing) is still valid. The pre-trip is valid for 30 days in normal circumstances (from the date shown on decal).

* When the container arrives at the packing station, the exporter must double-check that the item's specifications have been met. Also, make sure there are no drain plugs in place and that the floor drains are open.

* The product must be "pre-cooled" to the required carrying temperature by the exporter. "A refrigerated container is designed / made to maintain product temperature – not to reduce product temperature to the appropriate carrying temperature," it's vital to remember.

* The exporter must ensure that the cargo weight does not exceed the container's allowable cargo weight, and that the gross weight (cargo and container) does not exceed your and the destination country's road standards; the weight parameters are displayed on the container door.

* Direct sunlight causes the compressor to overheat, high head pressure is generated, lesser refrigerating efficiency is attained, and higher running expenses are paid when an operating reefer container is stored with the machinery facing an extremely hot climate. When the ambient air temperature is 40 degrees Celsius and the compressor is exposed to direct sunshine, the compressor temperature can reach 50 to 60 degrees Celsius. If a compressor fails, it is meant to shut off.


Ensure the product is readily available for loading and is adjacent to the container doors. I.e., ensure the container is located as close as possible to the cool room doors.

Ensure the product is readily available for loading and is adjacent to the container doors. I.e., ensure the container is located as close as possible to the cool room doors.

Always load the container as quickly as possible, otherwise ambient temperature will impact on the container and the produce, usually this would be at a higher temperature, which will impact on the product quality if left for prolonged periods.

If loading does not occur in a "cold tunnel", do not pre cool the container, it is a waste of power & serves no purpose because the ambient air temperature will invade the container within minutes of the doors being opened. Furthermore, if the container is pre-chilled, condensation will form on the inside walls of the container when the ambient air interacts with the chilled air.

Image - Cargo should be stowed below the red line. The cargo must never be loaded above the red line of the container, if cargo exceeds the red line this will impede the air flow which could impact on the quality product out turn and possibly the refrigeration unit.

Ensure that the weight is evenly distributed throughout the floor space.

If using forklifts to load the product, ensure that the "T" bar floor grills are protected from damage, as any damage could cause restricted air flow during the transit to the buyer and impact on the quality out turn.

Ensure that the weight is evenly distributed throughout the floor space.

Ensure that the weight is evenly distributed throughout the floor space.


1. Confirm that the vehicle is capable of transporting the container, especially in terms of gross weight, and that it has twist lock fittings - chains are not allowed. Ensure that the reefer unit's power cable is properly stored within the unit casing, especially if the container was "on power" prior to transportation to the Terminal.

2. If being transported under refrigeration (i.e., generator), ensure the machinery is set correctly (as per h above). However, ensure the vents are closed during the transport movement to avoid pollutants / contamination i.e., diesel fumes from entering the container via the vents during the transport journey. Usually, the container machinery end is loaded behind the transport cabin.

3. If not being transported under refrigeration, the transporter must travel directly to the terminal. Transport of more than 2 to 3 hours (without refrigeration) will result in increased product temperature due to the product respiration during the transit. It has been shown in recent exercises that during the transport (during early morning) that the pulp temperature of produce increased by 3 to 4 degrees Celsius during a 6-hour transit – not conducive to a good product out turn!

4.Exporter must always ensure that his transport contractor has sufficient time to arrive at the terminal before the final Receival time. Exporter must check with NAUKA agent office for the final Receival times and if a late Receival is available on that particular day of delivery. Normally the Terminal final Receival times for refrigerated cargo is 1 hour before closure, this enables the container to be placed on power and checked to ensure the unit is operating correctly.

5. When the transport arrives at the Terminal, providing the ERA is completed correctly, the transport will be directed to the unloading area – if the ERA is not completed, the transport will be rejected & "turned away".


Deposit / Damage Recoveries at POD and Acceptance of MTY Reefer Container

* PSL agents must collect appropriate deposit from consignee in order to collect damage and cleaning charges (if any).

* On receipt of MT reefers, all depots must thoroughly inspect the reefer unit + the container (as per latest edition of IICL standards) and raise an EIR indicating all missing parts, damages and cleaning requirement and obtain the trucker's signature, identification number and truck registration number for future reference. The Line copy of EIR needs to be submitted to PSL agent along with EOR for recoveries.

Phase power is required to operate the refrigerated container. Further, under no circumstances should the plugs be tampered with as electrocution could occur.


* PSL agent must keep their reefer technicians and depot operator(s) fully informed of the pre-trip requirements and when the containers are required for clients. It is essential that there is regular dialogue between the Line & exporters.

* Although much of the modern machinery is electronically controlled, the pre-trip procedure must be defined clearly, as any repairs / part replacements are essential to ensure the machinery operates effectively (to ensure the cargo arrives in prime condition). Each port will have interpretations of the length of time that a pre-trip occurs (relative to various costs), consequently the following is the pre-trip procedures for PSL.

* Depot operator and reefer technician are to be advised at least 24 hours in advance of a pre-trip requirement.

* On notification depot should wash the reefer container internally to free from any residue. If the external walls are "dirty", these must be cleaned to ensure a good presentation of the equipment. Depots are to ensure that the floor drain outlets are clear & during the steam cleaning, open the outlets to allow the water / condensation to escape in the correct manner. Once washed, containers should be placed in plugging area for Pre-trip inspection, in a manner that the container could be access easily by the technicians.

* After completion of washing, pre-trip inspection to be carried out by the appointed reefer technicians. If any defect found during pre-trip inspection, PSL agent to be notified immediately with the EOR for repair.

* Upon receipt of EOR from reefer technicians, PSL agent should refer to PSL – DXB (HQ) for approval of repairs. Once the repairs are approved, reefer technicians must carry out repairs and should return all the damaged parts to PSL agent's office

* The pre-tripped container is then placed in the "available" stack.

* Prior to release of reefer to exporter, depots are required to raise an EIR indicating all necessary parts of the reefer and confirming cleanliness of the interior/ exterior and obtain trucker's signature, identification number and truck number for future reference and Line copy of EIR should be submitted to PSL Agent. Depots can use their own EIR for this purpose.

* On all occasions, the container must be lifted with either an appropriate lift truck fitted with a side frame or straddle carrier. Under no circumstance the reefer container should be lifted with a forklift.



* Transport contractors must use trailers fitted with the twist lock fittings to ensure safe transport (there have been serious accidents, unfortunate deaths had occurred where chains have broken during the transport movement)


*The PSL agent must communicate with vessel operator to define the final time for delivery of reefer containers to the terminal (Port), it is essential that this information together with the proposed vessel movements are communicated to the refrigerated cargo exporters and packing stations, preferably in writing i.e. fax or e-mail.

* If the vessel operator has approved "late delivery", PSL agent must liaise with the reefer exporters and packing stations should additional time be required to achieve the delivery to the Terminal. Where necessary appropriate advices are sent to the vessel operator and the Terminal.

* Providing the ERA that is completed correctly, the transport will be directed to the terminal reefer stack where the straddle will off load the unit and place the unit at the sequenced stow point. The temperature and vent settings are then checked (against the ERA information) and if necessary adjusted to the correct (required) settings.

*Ideally the container should remain on power at the terminal for at least 24 hours prior to loading to stabilize the temperature of the produce.

*Until the container is loaded onboard the vessel, the Terminal staff monitors the temperature readings (return air) at least twice daily. Should there be any irregularities, the Terminal will contact PSL agent and they need to inform their nominated reefer technician for immediate action and where necessary repairs are performed to ensure the container is operating correctly. (Many instances the "call out" is because the product temperature was loaded in excess of the required carrying temperature, thus the temperature reading is above the required carrying temperature – poor cold chain practice!). The terminal and reefer technicians must record all "call outs" and temperature readings. It is suggested that the majority of "call outs "are resulting from "hot loads. I.e. the cargo has been loaded at much higher temperatures than the required carrying temperature; sometimes this may be high as 5 times the required carrying temperature.

*he PSL agent needs to make sure that the nominated reefer technicians are available for call out 24 hours a day, 7 days a week.



* When the containers are loaded onboard the vessel, the PSL agent should liaise with the vessel operator and need to make sure that the vessel operator's technicians check all reefers loaded are operating correctly as per the reefer container list. The vessel's chief engineer or electrician must be present during the "pre sail inspection" as they are required to sign the ERA acknowledging receipt of the containers and that they are operating in accordance within the details indicated in ERA, which supplied by the PSL agents at the load ports.

* During the voyage, the vessel's Chief Engineer or Electrician monitor all reefers onboard, generally 3 times per day. Appropriate action is taken when necessary as "spare kits "for each type of container machinery are retained onboard to enable prompt corrective action. The reefer monitoring is based on the reefer container lists supplied by each load port, this is collated from the Exporter's ERA's.

* In port of delivery, PSL agents are required to collect the entire reefer monitoring data from the vessel operator and the port and to keep all the records safely for any future reference.



* ? Within 24 hours of the vessel's departure, PSL agents at all load ports should communicate full details of each reefer container shipment to each final port of discharge and the trans-shipment departments of all T/S ports. PSL agents should also make sure to communicate with all T/S ports' trans-shipment departments to ensure that trans shipments containers are connected to 2nd carrying boats on a timely basis.



* The reefer containers are powered by gensets, which maintain the fixed temperature during rail or road transit. There are two types of Gensets: clip-on Gensets and under-slung Gensets that are installed beneath the chassis. There is an additional price when using Gensets.



Packing groups are used for the purpose of determining the degree of protective packaging required for Dangerous Goods during transportation.

1. Group I:Great danger, and most protective packaging required. Some combinations of different classes of dangerous goods on the same vehicle or in the same container are forbidden if one of the goods is GroupI

2. Group II:Medium danger

3. Group III:Least danger among regulated goods, and least protective packaging within the transportation requirement
