ANTI FUNGAL TREATMENTS
- Are your goods damaged during shipping?
- Are they attacked by moisture during shipping?
- Are your drums / cartons damaged from moisture during transit?
We have all the solutions towards your problems.
Ship goods without the threat of "Container Rain" Inhibits the formation of mold, mildew, rust and corrosion.
For many years, thousands of containerized cargoes are damaged by moisture problems. When the containers arrive at the destination, metal is found to be rusty or oxidated, cartons become soft and moldy, beans may be damp, such losses sometimes costs several million dollars.
It is caused by two main reasons:
- Container Rain
- Cargo Sweat
Four Areas of container moisture damage:
1. The ceiling and inner walls of the container, the condensation is known as "Container Rain"
2. The surface of cargo, the condensation is known as "Cargo Sweat"
3. The container floor. There are two kinds, iron floor is cold, wooden floor contains moisture inside. They both easily make the pallets moldy.
4. The container doors. The outside wet air easily goes through the crack of the container door and causes high relative humidity.
When containers are loaded and shipped through fluctuating temperatures and relative humidity the possibility of condensation occurring is substantial as temperatures drop.
We apply products which help keep the dew point temperature below the actual temperature, even when the actual temperature drops within the shipping container due to fluctuations. ("Dew Point Temperature" is the temperature at which water vapor begins to condense onto a surface forming liquid water).
The liquid that results inside a container is called "Container Rain". Container rain will occur if the surface temperature of an object is equal or lower than the dew point temperature.
If the relative humidity is lowered with the absorbing properties of some kind of a product, the dew point temperature is also lowered, stopping container rain.
What causes condensation in your container?
- Containerised cargo can be subjected to significant temperature variations when stored on deck in the sun, whilst in storage awaiting trans shipment, or whilst crossing the equator.
- As the temperature in the container rises the enclosed air is able to absorb more moisture. There are many sources of moisture in a container - the wooden floor and pallets, packaging material and possibly the cargo itself.
- Conversely, when there is a drop in temperature the air is not able to hold this extra moisture, which is then released in the form of condensation. The temperature at which this condensation takes place is called the DEW POINT.
- Then as the temperature drops, i.e. during the night, during atmospheric changes, or when the ship moves into a colder climate, the moisture is released and condenses on the container's roof and sides.
- The water that drips from the roof of the container, together with the condensation that forms on the product causes corrosion, mould, caking of powders, and damage to labels and packaging.
- This process of warming and cooling repeats itself numerous times during a voyage, causing the damaging moisture cycle to repeat itself.
- Our products are manufactured under controlled conditions in order to assure you of an absolutely dry desiccant upon delivery.
- After your container has been packed, we apply the desiccant which will immediately start to absorb any moisture present inside the container.
- On the container doors being closed, Dessicant controls the humidity inside the container by continuously absorbing the moisture from the enclosed air inside the container. Dessicant is designed to hold the moisture and not release it back into the container's climate.
- As the humidity inside the container is kept continuously low, the air is dry enough to prevent condensation forming at low temperatures.Dessicants will continue to absorb the moisture until it has gained approximately 150% of its own weight.
It has the ability to protect shipments from start to finish, through all temperature ranges and relative humidity variances.
Completely safe, non-toxic materials. Container Sac Desiccants can be disposed with regular waste as they are very reasonably priced.
