The Condensation Terminator Sheet (CT Sheet) is a countermeasure solution used to prevent moisture damage in cargo and at the same time measure the moisture damage in shipment.
Shipping Container Condensation
Condensation occurs when water vapour in the air of the container turns into a liquid, rises, and condenses on the walls and roof of the container, forming water droplets. As the walls of the container are made from metallic materials which are great insulators of temperature, condensation occurs readily as the environment easily influences the temperature of the container. As condensation occurs frequently, the water droplets accumulate and become denser, eventually falling and dripping onto the surface of the goods. This results in packaging deterioration, corrosion, mild dew, moulding, and other damages caused by the water droplets to take place if no action is taken. Further damage may occur within the packaging resulting in more significant losses.
Condensation Terminator Sheet
The Condensation Terminator Sheet (CT Sheet) is a water-absorbing sheet that functions by catching condensation droplets from the walls of the container. Not only does the CT Sheet acts as a barrier to water droplets, but it is also durable and does not sag. Hence, water leakage will not happen even after absorbing a large amount of water.
The Container Terminator Sheet is designed with special hooks to be hooked to lashing rings and tied to lashing bars at the corners. The inner side and door side of the CT Sheet should be attached to the ceiling with adhesive tapes.
- Maintain a 20cm gap between the CT Sheet and ceiling of the cargo
- Cargo should not be touching the CT Sheet
- Ensure that the surface of the cargo and CT Sheet does not have any dirt or oil
- Ensure that tape areas of the container are dry so that CT Sheet does not fall off and remains fixed
- Lashing rings are needed to attach CT Sheets at roof corners
- CT Sheet should be stored in a warm environment
To summarise, the Condensation Terminator Sheet is an easy-to-use and cost-effective solution to prevent moisture damage in containers. No cleaning is required after each use, and it can be easily stored. Although it is applicable for a broad range of goods, performance may differ due to environmental conditions and the physical properties of the cargo.
