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.

Installation Guidance

  1. 1Check that the container is dry and clean before installation.
  2. 2Hang the product vertically in a well-ventilated position inside the container.
  3. 3Avoid prolonged direct contact between the product and cargo surfaces.
  4. 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.

Frequently Asked Questions

No. This product uses Calcium Chloride (CaCl₂) technology combined with a gelling agent, which differs from granular silica gel — CaCl₂ actively absorbs moisture and gradually transitions from powder to gel as it absorbs.
