Discover effective anti-condensation solutions to protect your storage containers and reduce humidity and water-related damage.
Humidity in storage containers is caused by condensation, mainly on the ceiling in the morning. The drops of water then fall on the ground and stored products, causing damage: warped cardboard, stained papers, moldy fabrics, etc.
Why does water form on the ceiling?
The ceiling is colder than the air inside. During the day, the air is heated by the sun. At night, outside air cools more quickly, making the ceiling a “cold spot” where water condenses.
What anti-condensation solutions?
Two main strategies can be used to combat condensation:
1. Reducing the temperature difference
Ventilation : Installing ventilation vents allows the exchange of indoor and outdoor air. However, without forced ventilation (VMC type), the effect remains limited.
Thermal insulation : Installing a cork or polyurethane coating increases the temperature of the ceiling and eliminates the cold spot. Effective but complex and expensive solution.
2. Reducing the water content in the air
Condensation dehumidifiers : These devices suck in the air, cool it to condense the water, which flows into a container. Advantages: efficiency. Disadvantages: power consumption and regular draining.
Absorbent materials : Calcium chloride captures water, but is slow and not regenerable.
Air Sponge : Quickly reduces humidity when it exceeds a certain level, regenerates spontaneously, works without electricity and is easily installed even in a filled container.

Summary and recommendation
The ribbon Air Sponge is characterized by the best cost/efficiency ratio and ease of use. It limits humidity in containers, without the need for electricity or frequent maintenance.
