Controlled Atmosphere Technology
The transport of fresh produce is a complicated process because each variety of produce has unique characteristics that are related to recommended temperature, fresh air exchange, shelf life which affects the conditions in which they are carried in a reefer container. All fresh fruits and vegetables are living products and respire. The rate of respiration for any given product will depend on its variety (cultivar), area of growth and the seasonal and climatic conditions experienced during periods of growth. The storage life of produce varies inversely with the rate of respiration, which means that produce with short storage expectancy will usually have higher rates of respiration, eg fresh broccoli, lettuce, peas and sweetcorn. Conversely, potatoes, onions and some cultivars of grapes with low respiration rates have longer storage lives.
COOLXTEND CA+
Always Active, Instant Freshness
ONE COOLXTEND CA+ is the most technologically advanced control atmosphere system in the market to extend shelf-life and safeguard freshness of perishable cargoes. Deploying stage of the art VPSA* technology with self-contained nitrogen generator, COOLXTEND CA+ blankets cargo with rich nitrogen to establish optimum atmosphere rapidly. It precisely controls atmospheric composition throughout the transit for produces to enjoy instant freshness preservation and reach distant markets in prime condition. For more information, please refer to our COOLXTEND CA+ customer handout
*VPSA = Vacuum Pressure swing adsorption.
Fruits that benefit from COOLXTEND CA+: Avocado, Blueberry, Banana
COOLXTEND CA
Under COOLXTEND CA solutions, ONE offers a broad range of different technologies to our customers which helps to control interior atmospheric composition of gasses to delay the ripening process of fresh fruits and vegetables. These technologies are crucial to prolong the shelf life of fruits or vegetables by adjusting the O2 and CO2 concentration of the cargo.
- Special Membrane technology which allows controlled removal of CO2 from atmosphere surrounding cargo to outside of the container.
- Allow ambient fresh air to regulate atmosphere inside container, when respiration lowers O2 setting.
- Vacuum pump creates pressure differential across membrane, exhausts CO2 outside of container.
- Proven its value for banana and avocado cargos, increasing the transportation window to as much as 45 days.
- Ideal for low respiring cargo; where tailor-made atmosphere is aimed via pre-trip gas injection model. An additional controller is monitoring & recording the atmospheric composition inside the reefer.
- O2 concentration by cargo respiration & fresh air injection using valves.
- CO2 Concentration by scrubbers / membrane technology & valves monitors.

For more information, please refer to our COOLTemp customer handout
Fruits that benefit from COOLTemp: Blueberry, Mandarin, Apple, Kiwi, Grape, Citrus, Stone fruit, Lychee, Longan, Starfruit
Fresh Air Ventilation
- Fruits and vegetables will continue to respire and produce heat and other gases (CO2 and ethylene). These gases can induce cargo damage such as discoloration and uncontrolled ripening, resulting in reduced shelf life.
- Therefore, heat and unwanted gases should be removed from the container through ventilation (Air Exchange). Reefer containers can provide vent openings in the 0-250 m3/h range.
- The required air exchange ratio varies from commodity’s respiration rates, ethylene production and sensitivity.
- There are 2 points to remember for setting up ventilator:
1. In principle, ventilator should be closed except when transporting fresh produce (chilled mode).
2. The maximum air exchange rates vary for different reefer machine makers. Hence, it is important to specify desired air exchange rates in M3/Hour (not in percentage %) to avoid confusion.
ONE reefer containers are incorporated with different reefer machine makers to ensure fresh air ventilation for the cargo.
De-Humidification
ONE reefer containers are equipped with dehumidification function (selectable range between 65% to 95% RH**) in order to prevent germination and decay; which is suitable for transport of some chilled reefer cargo such as fresh garlic, onions, flower bulbs
Key points:
- Reefer machine is only equipped with De-Humidification, so as not to increase humidity inside the container.
- De-humidification is activated should humidity inside the container is higher than the humidity setting.
- The performance of dehumidification depends on type of commodity, packaging and ventilation (air exchanges) and atmosphere condition (i.e. temperature and humidity level). Hence, there is no guarantee to keep the humidity setting.
- Reefer machine is equipped with heating elements and or re-heater coil (depending on machine make) enabling dehumidification.
Unit Specifications
ONE has one of the largest and modern integrated reefer container fleets in the world. These containers are made of modern materials and advanced light weight refrigeration units which ensure that customers can benefit from higher payload capacity in each container. These reefer containers are mainly of two sizes i.e. 20ft and 40 HC and built according to stringent testing and highest technical standards.
The refrigeration unit is built onto the nose of the container and power is provided by a motor generator (when container is on wheels), by terminal (when grounded in a yard) or by the ship (when laden on board). Air, cold or warm, is supplied to the inside of a container via an air duct system that enters the container from the bottom. Air circulates under, over and through the load before it returns to the refrigeration unit. This circulation is repeated continuously when the unit is in operation.
In the nose of each refrigeration units are adjustable ventilation holes. At specific settings, these vents allow fresh air exchanges to avoid a build-up of carbon dioxide inside the container. All fresh fruits and vegetables are living products and as a result, emit heat and carbon dioxide. Vents allow this warm toxic air to be expelled from the container to avoid spoilage. These advanced reefer containers are computerized, enabling highly precise temperature control. Transportation has become easier due to this type of precise control that ensures preserving the quality of foods such as meat, fish, eggs, vegetables and fruits, as well as films, plants and pharmaceuticals.
Benefits of Non-Operating Reefer (NOR) to Customers
Every year container shipping industry spends billions of dollars carrying empty reefer and dry containers to market demand locations around the world – which is logistically challenging and also inefficient in operations. NORs offer an opportunity to solve this problem thereby also contribute to reducing container shipping industry’s carbon foot prints.
Offering of Non-Operating Reefer (NOR) or Reefer as Dry (RAD), is to minimize empty reefer repositioning cost in Dry Dominant/Reefer Non-Dominant legs, especially out of Asia. ONE allows the use of reefer containers in non-operating mode to carry “approved” dry cargo to reefer demand origins. This type of cargo is known as NOR or RAD and is approved for packing into refrigerated containers for transportation without the refrigeration machinery being switched on. ONE’s NORs transport your dry cargo in a clean, food-grade insulated container with capabilities to protect against extreme shift in outside temperature.
SUPERIOR QUALITY OF CONTAINERS:
Reefer containers are generally used to carry perishable commodities only; hence quality and cleanliness of the containers surpass that of normal dry containers.
MINIMIZE TEMPERATURE FLUCTUATION:
Due to higher insulation quality of a Reefer container, NORs minimize temperature fluctuation impact to cargo during day and night. Typically commodities which are sensitive to temperature fluctuations are Chemicals/electronics devices/films/beans in bags etc.
PROTECTION AGAINST CONDENSATION AND MOISTURE:
Due to higher insulation quality of a Reefer container, NORs also provide protection to cargo against condensation and moisture.
IMMEDIATE BOOKING ACCEPTANCE, EQUIPMENT GUARANTEE, LOADING PRIORITY:
In trade lanes where ONE face typical reefer equipment imbalance, using NORs can also provide benefits to shippers such as immediate booking acceptance, equipment guarantees, loading priority over dry (although 'live' Reefer boxes will always take priority over NORs). Contact your ONE Local Sales representative for further details about ONE preferred port pairs to avail such benefits.
COMPETITIVE PRICING:
Possibility of better pricing compared to DRY at ONE Preferred port pairs. Contact your ONE Local Sales representative for further details about ONE preferred port pairs to avail such benefits.

Fresh Air ventilation
Fresh Air ventilation is an automated system designed to remove heat and unwanted gasses released from produce respiration inside a reefer container via the fresh air vents. ONE operates one of the largest reefer container fleet equipped with Fresh air ventilation ventilation capability.
Dehumidification
ONE reefer containers are equipped with dehumidification function (selectable range between 50 to 95% RH**) in order to prevent germination and decay; which is suitable for transport of some chilled reefer cargo such as fresh garlic and onions.
Refrigerated cargoes are usually perishable in nature, highly sensitive to temperature maintenance and likely to have a higher monetary value than most other commodities. The safe and successful carriage of refrigerated cargo critically depends on carriage instructions, which outlines the suitable and most optimum storage conditions during transportation. Although refrigerated cargo include both frozen and chilled goods, the range and diversity of the cargo can be quite extensive, including fresh fruits and vegetables; dairy products; fresh flowers; chilled/frozen fish and meat; etc. Nowadays, many pharmaceuticals are also carried in reefer containers, due to the highly sensitive and valuable in nature of the products. Chilled commodities such as fresh fruits and vegetables; begin deterioration right from the moment of being harvested as freshness gradually decreases. They can also be damaged by low temperatures, either by freezing or by chilling, causing injury to fresh produce. Hence, it makes storing and transporting them very challenging and requires specialized care, expertise and technologies to preserve freshness.
According to Food and Agriculture Organization of United Nations (FAO), about 1/3 food produced in the world for human consumption every year gets lost or wasted, leading to significant wastage of resources (including water, land, energy, labour and capital) and produce greenhouse gas emissions, contributing to global warming and climate change. As one of the leading carriers in refrigerated container industry, ONE has prepared this important guideline to raise awareness among all players involved in cold chain logistics with the goal to minimize amount of losses and food wastage. These recommendations that are considered as widely accepted best practices in the industry for handling any reefer cargo, have been drawn up to assist shippers.
Precool
While cargo pre-cooling is important; container pre-cooling could be detrimental and lead to cargo damage if not handled properly.
-
Pre-Cooling of Cargo: IMPORTANT
-
All perishable cargo should be pre-cooled to the recommended temperature before loading into a reefer container. Reefer container is designed to maintain within the range of pre-set temperature but not to achieve fast cooling of hot stuff cargo.
-
Loading without precool may cause considerable damage to cargo due to water loss and lead to spoilage for many perishable cargo.
-
If the cargo has been properly pre-cooling, temperature in the reefer container will reach the setting temperature within several hours.
-
-
Pre-Cooling of Container: AVOID
-
In case of precooled container, if the stuffing takes place in open environment then the difference in temperature outside and inside the container will cause moisture on all surfaces of the container when outside humid air flows in during the stuffing; which could be detrimental to cargo. (Picture below) This will dampen the cargo units and could cause the cargo to deform in stowage, possibly resulting in cargo damage.
-
In addition, the moisture produced on the inside of the container and the cargo will result in icing the evaporator coil once the machinery is started. Once the machinery is frosted like this, it will cause a reduction in refrigeration and hamper the airflow which will further delay unit to reach the set point.
-
One exception for Pre-Cooling the container prior to loading is when the cargo is loaded directly from a chilled storage through a tight duct between the chilled storage and the container, it called 'Cold Tunnel'. This direct linkage will prevent any moisture from entering the packing area.
-
Pre-trip Inspection
PTI – Pre-Trip Inspection is an extensive inspection done on empty reefer container to ensure that the reefer machinery is running properly at correct settings and that the container is clean and in sound condition, before allotting to customers for cargo stuffing. In ONE, our top most priority is to offer our customers with the most suitable and good quality reefer container for their needs. Hence, ONE follows a strict PTI policy by which all reefer boxes, must pass a thorough Pre-Trip Inspection (PTI) before allotting to our valued customers. Inspections conducted here are to examine the cleanliness of containers, the damages and the condition of refrigeration unit.
In addition, we also have a special PTI policy for high value, high sensitive cargo such as pharmaceuticals which has been carefully designed for preventive maintenance value based on our legacy experience in transportation of High Value commodities.
Air Circulation
In the refrigerated container, cold air circulates to wrap around the cargo. To maintain this air flow, refrigerated container has rails called T-rails laid on the floor. The cold air blown out from the freezing unit is blown into the T rail from the bottom of the unit and goes towards the door side. The cool air reaches the door, rises, passes through the top of the cargo and returns to the unit.
A red line is drawn on the wall inside the refrigerated container. It shows load restriction and indicates not to load cargo up to the height beyond the line. The red line is drawn near the ceiling and the door side. Loading more cargo over the restriction line Red line, it may lead to a poor air circulation and may not be able to maintain the cold temperature of the cargo. While stowing “Non Palletized” refrigerated cargo in flat-side wall reefer containers, slight loose stowage is suggested for smooth circulation of air evenly around the cargo and also for ensuring that any heat penetrating the container walls does not come into direct contact with the cargo package.
Chilled Cargo
Chilled cargo is highly perishable premium food which can gradually ripen during shipment. In this illustration, the degree of air flow through the cargo is largely dependent upon the stuffing pattern at the door.
Frozen Cargo
If frozen cargo is pre-cooled to the correct carrying temperature, it is only necessary for air to circulate around the periphery of the load. A block stow, i.e., one that has no deliberate spacing between any of the packages or pallets, is all that is required. However, it is necessary to ensure that air can circulate under, over and to each side and end of the stow.
Stowage
The cold air that maintains a constant temperature is blown out from the bottom of the rear panel of the reefer unit. Then, the cold air goes through the floor rail (T-bar) to the door side. When it reaches the door, the air is sucked into the top of the rear panel and the air is circulated through the inside continuously. We called the location where the cold air is blown out as “Supply Air”, and the location where the cold air is sucked in as “Return Air”. Thus, do not block the air flow. Please see below Figure #3.
When a huge volume of cargo is loaded, the cold air circulation is entrapped, and it makes temperature control harder. There are Load Limit Mark, Red lines, to indicate the maximum loading capacity on side panels inside the container. Over loading exceeding the “Limited Lines” is prohibited. This Load Limit Mark, Red line, mounted from the ceiling to under 75mm/20ft. and 100mm/40ft. Please see below pictures.
Hence, we never recommend below examples of over loading.

Chilled Cargo Stowage Best Practices
- The key is to allow proper air circulation and flow-through so that heat, vapour, CO₂, and other gases produced by the respiration process from chilled perishable products can be removed.
- Proper packaging such as packaging style and package material is necessary to support stacking weight and sustainability at various humidity levels.
- Any packaging accessory like shrink-wrap, slip sheets, foam trays and plastic bags which can block or obstruct air passage should not be used.
- Proper air passage on the package, including proper size/number/ places of ventholes on cartons, is needed to allow refrigerated air to circulate through all the cargo in the container.
- Proper stuffing is required to allow refrigerated air to circulate through the package material and throughout the entire load.
- If the cargo cannot cover an entire floor, cardboard can be used to cover empty spaces to allow for smooth refrigerated airflow.
- There must be no stowage above the indicated red line on the container walls to avoid impeding return air flow.
Frozen Cargo Stowage Best Practices
- As the frozen cargo should have been appropriately pre-cooled to the desired temperature before loading, air circulation should be aimed at blocking and preventing heat penetration from outside the container.
- The entire floor should be evenly loaded and covered.
- Proper corner support of cartons or pallets is needed due to the weight and loading pressure.
- Stowage must be kept below the red-line to avoid air circulation blockage. The key is to allow air circulation around the cargo.
- Ventilation and dehumidification must be set to “Off”. Drain port must be “Closed”.
- Solid block stowage, leaving no space between the packages or cartons, is preferred to avoid hot pot or short-circuiting.
Pre-loading Guideline
Before Loading Checklist
- Inspect the reefer container to ensure equipment is in good condition.
- Check and clean T-floor to ensure air channel is clear from the panel to the door.
- Pre-treat the products.
- Pre-cool the products to carriage temperature range.
Note: hot stuffing may damage both the equipment and cargo itself. - Do not pre-cool the container, except when goods are being loaded at a cold facility where these is a sealed connection to the container loading bay.
Note: While reefer cargo is generally classified according to the storage temperature, specific reefer set-points vary according to the exact cargo commodity type.
