CARGENTRA Hanging Container Desiccant 1000g
A multi-compartment CaCl₂ hanging desiccant designed to control excess moisture and reduce the risk of container rain during storage and transportation.
- Calcium Chloride (CaCl₂) technology
- Nominal weight of 1000g
- Multi-compartment hanging-strip design
- Absorption capacity up to 300%, depending on conditions
The "Container Rain" Problem in Transit
Temperature swings between day and night during ocean transit can cause water vapor inside a container to condense into droplets — commonly known as "container rain". This condensation can drip onto cargo below, affecting carton packaging, wood products, metal components, and certain consumer goods.
Calcium Chloride (CaCl₂) Desiccant Technology
Calcium Chloride (CaCl₂) is an actively hygroscopic material commonly used in moisture-control solutions for containers and enclosed storage. Combined with a gelling agent, absorbed moisture gradually transitions from a powder to a gel state, helping retain moisture within the product structure rather than letting it drain freely.
Multi-Compartment Hanging-Strip Design
The product has a compartmented design on a single hanging strip, helping distribute the active material more evenly and keep the structure stable throughout moisture absorption. The hanging format allows vertical installation inside a container without taking up floor space or interfering with cargo loading and unloading.

Applicable Industries
Furniture & Wood Products
For long ocean routes or humid climates, pairing with a moisture-control solution helps reduce warping and mold risk.
Electronics & Home Appliances
High humidity can affect circuit boards and packaging — additional desiccant solutions are worth assessing for higher-risk routes.
Consumer Goods
For goods with paper components or moisture-sensitive materials, a moisture-control solution is worth considering on longer routes.
Packaged Food & Beverage
Moisture control is particularly important for dry foods and paper-based packaging to reduce mold risk.
Logistics & Warehousing
For warehouses with limited humidity control, it is worth assessing seasonal desiccant needs as well.
Installation Guidance
- 1Check that the container is dry and clean before installation.
- 2Hang the product vertically in a well-ventilated position inside the container.
- 3Avoid prolonged direct contact between the product and cargo surfaces.
- 4Confirm the quantity and installation positions match the actual stow arrangement before closing the container doors.
Final detailed installation guidance must follow the product's technical documentation and the actual conditions of each shipment.
How to Determine Quantity
Recommended quantity is based on cargo type, container size, route, and transit duration — not a fixed number applied to every container. Factors to consider include how moisture-sensitive the cargo is, container size (20ft or 40ft), the climate and season along the route, and expected transit time.
CARGENTRA recommends sharing your specific shipment details to receive a tailored quantity recommendation.
Note on Input Moisture Control
The hanging container desiccant helps control in-container air humidity during transit, but does not replace ensuring cargo, packaging, and pallets are sufficiently dry before loading. Moisture already present in the cargo or packaging itself (input moisture) still needs to be controlled at the packing stage.
