What are the functions of the additional equipment of the TLS offshore container refrigeration unit？
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.

Offshore containers should be inspected regularly every year. Regular inspections should be performed on the inside and outside of the container when it is empty. TLS has prepared tips for you to check including:
- Inspection of signs and nameplates.
- Weld inspection of main structural members to confirm that there are no visible defects.
- Inspection of lifting lugs and lashing points for deformation, mechanical damage, or other dangerous defects.
- Inspect all structures for corrosion, deformation, mechanical damage, or other dangerous defects.
- Check the condition of the container floor, including the bottom drainage facilities and drainage holes.
- Check for corrosion and mechanical damage inside the fork pockets (where applicable).
- Check the door, frame, seal, hinge, door lock, etc., and confirm the opening and closing of the door.
Negative air pressure is a safe containment solution in which more air is taken in than is expelled.
Negative air pressure in the environment does not mean that the actual pressure is negative because, according to science, absolute pressure can never be less than zero. Negative air pressure means that the pressure within an environment is less than the pressure of its surroundings. As air flows from high pressure to low pressure, this difference in pressure level acts as a vacuum effect and causes air to flow in from the outside.
The negative air system produces a vacuum effect or a direction of air flow into the space by creating and maintaining the air pressure differential. In doing so, it restricts the spread of contaminants such as dust and mould and pollutants such as bacteria and viruses from the controlled space to the outside.
This system traps dangerous and infectious particles in the air and removes them by means of a blower and a group of filters.
In summary, when the external environment is safe, but toxic and harmful gases are generated inside, negative pressure is preferred

• Laboratory container / cabin
• Blast Resistant Container, Blast proof Container
• Mud Lab

To facilitate the loading and unloading of the cargo, the bottom of TLS offshore containers is usually designed with fork pockets, which are required as follows:
1. If provided, the fork pockets shall be arranged in the bottom structure with the top closed to penetrate the bottom and prevent the offshore container from overturning from the fork tine.
2. The net opening size of the fork pocket of the offshore container shall not be less than 200mm×90mm.
3. Considering the length, height, width, and rated weight of the offshore container, the position of the fork pocket should ensure the stability of the container when it is transported by the forklift. The fork pockets should be as far apart as possible, generally not less than 900 mm from the center, but not more than 2,050 mm.
4. The bottom plate of the fork pockets can be closed completely, but openings are recommended for maintenance and to reduce the risk of loose items being left in the fork pockets, thereby preventing items from falling during the lifting process. Where openings are provided, the size and position of the opening should be set to avoid jamming or being damaged by the tines The opening at the bottom of the fork pockets are not allowed at the bottom side rails, and the distance between the opening and the bottom side rails should not be less than 200mm.
5. The weakening of vertical shear strength of bottom side rails by fork pockets opening should be taken into account when calculating the bottom side rails strength. In general, a reinforcement plate should be attached to the top of the bottom side rail. The reinforcement plate should be in the same plane as the bottom side rails web. The reinforcement plate should be extended by at least 100mm at both ends. At this point, the weld between the reinforcement plate and the bottom side rail should be completely melted through.

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.
