Shipping containers are the backbone of global trade, transporting goods across continents and oceans. They are designed to be robust and durable, capable of withstanding harsh conditions during transit. However, one challenge that persists is the formation of condensation inside these containers, a phenomenon also known as “container rain.” This happens when the temperature inside the container fluctuates, leading to the condensation of moisture present in the air. The resulting droplets can fall onto the cargo, leading to potential damage such as mold, corrosion, and warping.
The problem of container rain is particularly prevalent in routes that involve significant changes in climate. For instance, a container traveling from a cold country to a tropical one can experience a substantial increase in internal humidity levels. This is where container desiccants come into play. Desiccants are substances that induce or sustain a state of dryness within its local vicinity. They achieve this by absorbing moisture from the air, thus reducing the relative humidity inside the container.
One such desiccant that has proven to be highly effective in this regard is InterDry Power Desiccant. This article aims to provide a comprehensive guide on how to calculate the quantity of InterDry Power Desiccant required for your shipping containers, ensuring optimal protection for your cargo.
Understanding InterDry Power Desiccant
InterDry Power Desiccant is a high-performance moisture absorber specifically designed for shipping containers. It stands out from other desiccants due to its exceptional absorption capacity – it can absorb more than 300% of its weight in moisture. This is significantly higher than many other desiccants in the market, making InterDry Power Desiccant a preferred choice for many businesses involved in shipping goods.
The secret behind InterDry Power Desiccant’s high absorption capacity lies in its composition. It is made up of calcium chloride, a hygroscopic material known for its excellent moisture-absorbing properties. When exposed to humid air, the calcium chloride in InterDry Power Desiccant absorbs the moisture and converts it into a brine solution, which is then retained within the desiccant bag. This process continues until the desiccant has reached its maximum absorption capacity.
But the benefits of InterDry Power Desiccant extend beyond its high absorption capacity. It is also designed to be leak-proof, ensuring that the absorbed moisture is securely contained and doesn’t come into contact with the cargo. Furthermore, it is non-toxic and environmentally friendly, making it safe to use with a wide variety of goods.
In the next sections, we will delve into the specifics of how to calculate the quantity of InterDry Power Desiccant required for your shipping containers, taking into account factors such as container size, cargo type, and journey duration.
The Importance of Correct Container Desiccant Quantity Calculation
The use of desiccants in shipping containers is not merely about placing a few packets here and there. It is a precise science that requires careful calculation and consideration. The goal is to maintain an optimal humidity level inside the container that prevents the formation of condensation, without incurring unnecessary costs.
Underestimating the quantity of desiccant can lead to inadequate moisture control. This can result in the formation of condensation and subsequently, damage to the cargo. On the other hand, overestimating the quantity leads to unnecessary expenses. Desiccants, especially high-performance ones like InterDry Power Desiccant, represent a significant cost in the shipping process. Using more than required is a wasteful expenditure that businesses should strive to avoid.
Moreover, the correct quantity of desiccant also ensures that the product performs at its maximum efficiency. Each desiccant is designed to absorb a specific amount of moisture. Once it reaches its absorption capacity, it cannot absorb any more moisture, regardless of how much is present in the environment. Therefore, using the right quantity ensures that the desiccant is fully utilized, providing the best protection for your cargo.
Factors Influencing the Quantity of Container Desiccant Required
The quantity of desiccant required for a shipping container is influenced by several factors. Understanding these factors is crucial for accurate calculation and optimal moisture control.
- Size of the Container: The larger the container, the greater the volume of air inside it, and consequently, the more moisture that can be present. Therefore, larger containers generally require more desiccant.
- Type of Cargo: Different types of cargo have different moisture sensitivities. For instance, electronic goods and metals are highly sensitive to moisture and may require more desiccant. On the other hand, some goods like textiles and certain types of food products might be less sensitive.
- Packaging Material: The material used to package the cargo can also influence the quantity of desiccant required. Some materials, like certain types of plastic, are less permeable to moisture, reducing the need for desiccant. Conversely, more permeable materials might require more desiccant.
- Shipping Duration: The longer the shipping duration, the longer the cargo is exposed to potential moisture. Therefore, longer journeys typically require more desiccant.
- Climatic Conditions During Transit: The climatic conditions that the container will be exposed to during transit also play a significant role. Routes that involve significant changes in temperature and humidity levels, or routes that pass through particularly humid regions, may require more desiccant.
How to Calculate the Quantity of InterDry Power Desiccant
The calculation of the quantity of InterDry Container Desiccant required for a shipping container is a precise process that takes into account several variables. These variables are represented in the following formula:
W = (K * A * R * M) / 14
Let’s break down each variable in this formula:
- W (Weight of the Desiccant): This is the result we are looking for – the weight of the InterDry Power Desiccant required for the shipping container. It is measured in grams.
- K (Environmental Variable): This variable represents the environmental conditions that the shipping container will be exposed to. It is usually set to 40 in high temperature, high humidity countries and to 12 in low temperature, low humidity countries. This variable is crucial as it adjusts the calculation based on the expected environmental conditions, ensuring that the calculated quantity of desiccant is appropriate for the specific climate.
- A (Volume): This is the volume of the container in cubic meters.
- R (Expected Relative Humidity): This variable represents the expected relative humidity inside the container, expressed as a percentage. Relative humidity is the amount of moisture in the air compared to the maximum amount the air could hold at the same temperature. The higher the relative humidity, the more desiccant is required.
- M (Months): This is the time in months that the desiccant is to be effective.
The denominator of 10000 in the formula is a conversion factor that adjusts the units of the variables to give the weight of the desiccant in grams.
By using this formula, you can accurately calculate the quantity of InterDry Power Desiccant required for your shipping container, ensuring optimal moisture control and protection for your cargo.
Practical Examples of Container Desiccant Quantity Calculation
Understanding the theory behind the calculation is important, but let’s put it into practice with some real-world examples. This will help you better understand how to apply the formula in your own situations.
Example 1: 20-Foot Container
Consider a 20-foot container, which typically has a cubic capacity of 33m3. We’ll assume that the container will be exposed to constant conditions of 40 degrees Celsius and 90% relative humidity over a period of 60 days.
Applying these values to our formula:
W = (40 * 33 * 0.90 * 60) / 14
The calculation gives us a result of approximately 5091grams. This means that for a 20-foot container under these specific conditions, you would need around 5-6 kilograms of InterDry Container Desiccant to effectively control the moisture levels inside the container.
Example 2: 40-Foot Container
Now, let’s consider a larger container – a 40-foot container, which typically has a cubic capacity of 66m3. Again, we’ll assume the same constant conditions of 40 degrees Celsius and 90% relative humidity over a period of 60 days.
Applying these values to our formula:
W = (40 * 66 * 0.90 * 60) / 14
The calculation gives us a result of approximately 10,182 grams. This means that for a 40-foot container under these specific conditions, you would need around 10-12 kilograms of InterDry Container Desiccant to effectively control the moisture levels inside the container.
These examples illustrate how the formula can be used to calculate the quantity of desiccant required for different container sizes under specific conditions. Remember, the actual quantity may vary depending on the specific conditions of your shipment, including the type of cargo, the packaging material used, and the climatic conditions during transit. Always ensure to make accurate calculations to protect your cargo effectively.
