New appointment with the automotive industry at BIAME
We are a global pioneer in stopping moisture damage in container transport
How and where
The harsh conditions of a container transport passing through several climatic zones with wide temperature and humidity fluctuations, rough treatment and long shipment times are often causing costly moisture damages. It appears as rust, mold, fungus, odor, discoloration, crumbling of cartons and direct product damage.Learn more
How and where
Moisture damage can be very unpredictable. Not every shipment suffers from moisture damage, so even if four container transports are perfectly safe, the fifth can be a disaster. Which may result in substantial losses and costs.
Very small differences in the cargo and voyage conditions can have a huge effect on the outcome. In some cases even a few tens of grams of water in the wrong place is enough to cause significant damage. And even small changes can result in big improvements.
The humidity of the air changes as a result of the change in temperature. When air cools it becomes more humid, even though the moisture content in the air remains the same. The humidity in a container will go up and down throughout the voyage, as a result of temperature fluctuations. If the temperature changes rapidly there is always a moisture risk, even if the container may be fairly dry.
Part of your supply chain
Protecting products from moisture during shipment should be as natural as protecting them from physical damage or theft. Our customers avoid costly moisture damage by making moisture protection an integrated part of their supply chain. They create a framework where the moisture protection applied is carefully specified. Important factors that affect the kind and number of desiccants needed to protect your cargo. Container:
- Weather conditions when loading?
- Is the container in good condition?
- Is the container airtight?
- Is the container dry when loading?
- Type of packaging?
- Dry or moist goods?
- Container position on vessel
- Temperature differences
- Relative humidity
- Duration and conditions during transport
Inside a container
Shipping in containers is an economical and safe way of shipping most types of cargo. But putting cargo into an enclosed steel box also means a constant risk of moisture damage for almost every kind of cargo on every voyage.Learn more
Inside a container
All containers contain moisture from the time of loading. No container is completely airtight. Moisture will move in and out of the container during the course of the voyage known as "container breathing".
By reducing the amount of moisture entering the container and by using desiccants to remove moisture from the air you can prevent the buildup of moisture to levels where it may cause damage.
Is the container airtight?
A minimum requirement is that the container is in good condition, without holes or damaged doors. This should be checked for every container before loading. Especially the doors are vulnerable to damage that may not easily be noticed. Check the ventilation holes. Certainly no container is airtight, but a container in good condition only allows air and moisture to move in and out of the container slowly. This significantly reduces the amount of moisture moving into the container under common circumstances. Tape the ventilation holes if you are shipping dry cargo.
Is the container dry?
A container that has been washed before loading may contain a lot of water. Pay special attention to the container floor. The humidity of the wood should not be above 15%. All pallets and wooden dunnage must be dry, certainly not above 20%. It is easy to check the moisture content of the wood with a handheld moisture reading device.
Warm air can hold more moisture than cold air. When temperature goes down, the air becomes more humid. If it is cooled enough, some of the moisture may condense. A fast temperature drop of 5° is often enough to cause problems. Water will condense on the coolest available surface, which usually is on the container ceiling or walls. From there it may drip down onto the cargo and cause damage, also known as container rain.
Why calcium chloride?
Calcium chloride is highly effective, it is one of the most hygroscopic materials when it comes to absorb moisture from surrounding air. It is also non-toxic and environmentally friendly. Calcium chloride desiccants work well over a temperature range from freezing point up to 80°C or more. Calcium chloride is the active compound in all Absortech products.Learn more
Why calcium chloride?
The combination of calcium chloride's aggressive moisture absorption and Absortech's patented design is protection that is proven superior to others.
Superior by nature
Calcium chloride (CaCl2) aggressively absorbs moisture from the air: It can attract several times its own weight in water, dissolving into a liquid brine if the air is humid enough and the temperature is high enough. The water is trapped in a membrane-protected chamber, which prevents captured water from spilling or reevaporating into the surrounding air.
Desiccant material absorb more moisture when the relative humitidity (RH) of the surrounding air is higher. At a RH of only 50% calcium chloride’s moisture absorption is 150% its weight in water. And its absorption increases exponentially as Rh rises, which is a remarkable result compared to other desiccants, such as silica gel and clay.
Our products prevents moisture from leaking onto the cargo or re-evaporating back into the air, which is not always the case with other desiccant materials.
Many other absorption materials contain moisture indicators that are produced with toxic Cobolt. Absortech products contain only calcium chloride, a naturally occurring compound abundant in seawater. It’s non-toxic and friendly on both the environment and on those who use our products.
Absortech is a knowledge-based company specialized in preventing moisture damage for all kind of industries during container transport. We know that each industry faces its own moisture challenges, and therefore needs its own solutions.Learn more
Research & Development
At Absortech, we are committed to provide better and more efficient solutions for our customers. That means to be at the forefront of moisture prevention solutions. Research & Development plays a key role in fulfilling this commitment.Learn more

- Assisting our sales, marketing and technical services teams with high-level technical support
We also work hard to create new solutions that increase durability, contribute to greater sustainability and increase productivity.
- Sustainable solutions: We want to contribute to a better environment, that’s why our R&D department concentrates on developing desiccant solutions with natural and unharmful substances, free from plastics.
- Increasing efficiency and productivity:
Moisture damage is as unpredictable as it is costly. No one knows for sure the costs, but the amount is substantial. Insurers estimate that approximately 12% of all container shipment damage is moisture related. Our R&D constantly focus on developing solutions that efficiently reduce moisture levels and replace other costly solutions.
Absortech invests heavily in product development in order to ensure our customers always have the best solutions.
- Focus on quality: We have stringent quality demands to ensure we deliver high-performing, environmental friendly products and solutions.
