Instructions for additional equipment related to refrigeration units such as CA, MA and humidity controllers.

• CA is short for Controlled Atmosphere.  It is an auxiliary facility that controls the levels of CO2 and O2 in the container.  The container should be airtight and have a nitrogen generator and source of carbon dioxide (such as a carbon dioxide compressed air bottle or scrubber). In both cases, the oxygen content is controlled by ventilation.
• MA stands for Modified Atmosphere.  This means that the container has an interface into which the mixed gas is injected before shipping.  During transport, the air composition in the container is no longer controlled.
• Humidifier can use a water source or condensate from an evaporator to humidify the circulating air. Dehumidification can be achieved by evaporative heating devices or chemical reactions. The humidity inside the chamber can only be adequately controlled if both dehumidification and humidification are available.

1.Keeps the temperature cold
The refrigeration unit distributes cold air through the floor of a refrigerated container  The floor of the container has slots, also known as T-shaped covers. This T-shaped cover allows a constant supply of cold air around the shipment.
 
If you are considering using a refrigerated container, you should be aware that it cannot reduce the temperature of your goods. A refrigerated container only maintains the desired temperature. Therefore, you will have to pre-cool your cargo to the temperature you want the reefer to maintain.
 
2.The genset provides electricity
Genset is short for generating set. It provides electricity to the refrigeration unit to operate. A refrigerator is usually connected to a power source on ships. But in the case of extremely sensitive cargoes that could spoil outside a temperature range, gensets provide a back-up power source. It is best to use a refrigerator equipped with a genset to ensure the safety of the cargo.
 
3.Ventilation keeps cargo cool
The purpose of a refrigerated container is to keep the cargo cool. Fruit and vegetables release heat, water, and CO₂. If these gases are not removed, they can damage the cargo leading to uncontrolled ripening, ageing, and altered taste. For this reason, refrigerators are kept ventilated with fresh air.

​20ft and 40ft are usually the most common specifications for shipping, 2 units 10ft containers are usually combined into 20ft when they are transported.

TLS is an international company that can customize onshore | offshore special containers for you.
Any requirements, please contact us directly:

Offshore refrigerated containers provided by TLS are equipped with DAIKIN, CARRIER or THERMO KING refrigeration units to maintain the internal temperature between -20°C to +25°C. 10ft, 20ft, 40ft or customised size reefer container for option.

Offshore Refrigerated Containers are reusable "portable units" designed to transport goods/food etc. on FPSOs or vessels. DNV 2.7-1 is considered the standard certification for marine reefer containers, and DNV 2.7-1 marine transport containers are certified containers for the oil and gas industry. DNV, BV, LR ABS classification societies can also certify DNV2.7-1 reefers according to DNV2.7-1 international standards.

The size of offshore reefer is diversified, and it also solves the needs of all customers for reefer size according to the size of FOSO, which is the best choice for all FPSOs and Vessel.

Certified by BV/LR, DNV 2.7-1 standard 10ft, 20ft reefer containers are being manufactured.
The 10ft/20ft reefer containers are our standard container type, but if you have any personalized needs, we can also customize and modify them accordingly. During the production process, our quality inspectors will track each production step, specific links, the third-party organizations such as BV/LR will also participate in the tracking quality inspection.

How does the refrigerated container work?
The purpose of the reefer container is not to cool the product, but to maintain the temperature of the product. So instead of adding cool air, the refrigeration process removes heat from the air inside the container.
The reefer container distributes cold air from the floor through the T-deck.​

A refrigerated |reefer Container is a closed container with refrigeration equipment and low thermal conductivity materials on the inner wall which is used to transport or preserve fresh fish, fresh meat, frozen food, fruits, vegetables, films, medicines and other required goods. 
Refrigerated containers are also divided into refrigerated containers and insulated containers.

• The reefer container is generally equipped with a built-in refrigeration device at the front end of the container. When the freezer is working, the cold air is blown out from the ventilation pipe at the rear end of the container. Through the gap between the protrusion on the wall and the ventilation rail on the bottom of the container, the cold air suction port on the front end wall is returned to the freezer for circulation.In order to improve the cooling effect, the walls, top and bottom of the entire reefer container are covered with thermal insulation materials. The working temperature of the reefer container is between -28°C and +26°C. It can be automatically adjusted according to the needs of the goods to keep the temperature in the container unchanged.
• Insulation containers are mainly used to load fresh goods such as fruits and vegetables. Generally, a refrigerant such as dry ice is used to prevent the temperature in the box from being too high; the usual holding time is about 72 hours. The inside of the container is completely heat-resistant.

Tips: 
Livestock and poultry meat
Include cattle, sheep, pigs, chickens, ducks, geese, etc. Usually, meat reaches a dormant state below -18°C, and if it is below -23°C, the refrigeration period can be doubled.

Frozen fish and aquatic products
The storage time of fish and seafood is closely related to temperature. Under normal conditions, the freezing period increases by a factor of 3 for every 10°C decrease in temperature. Low-fat fish has a shorter freezing period, while muscle red fish has a shorter freezing period.

Chocolate products
Shippers often ask to check that the humidity is set to 65%. Depending on the variety of chocolate, the temperature is usually between 8°C and 18°C.

Temperature control products
Goods that require temperature stability during transportation, such as films, medicines, food, etc. To avoid clumping and deterioration, the temperature was set between -2°C and 30°C.

Dangerous goods and harmful goods
Reefer containers maintain high standards and maintain quality for the transport of dangerous or sensitive cargo. This type of refrigerated container is distinguished by a particular color and logo.
​
Mixed refrigerated goods
Generally, it should be avoided to mix all kinds of fresh fruits and vegetables in the reefer container. Due to the volume, variety, cost and other reasons, pay attention to the temperature during transportation, Fruits and vegetables are mixed in containers. The closer the refrigeration temperature is, the better.
