Wisesorb Calcium Chloride Desiccant Refill Beads 3.2 kg – Fragrance-Free, High-Absorption Moisture Absorber

Wisesorb Calcium Chloride Desiccant Refill Beads 3.2 kg – Powerful Moisture Control

When ordinary desiccants aren’t enough, calcium chloride steps in. Wisesorb’s high-grade calcium chloride beads absorb moisture rapidly and efficiently — making them ideal for high-humidity environments where silica gel alone may fall short. Fragrance-free and ready to use straight from the bag.

Key Features

• High-Grade Calcium Chloride – 3.2 kg (7 lbs) of premium-quality desiccant beads with exceptional moisture absorption capacity, far exceeding standard silica gel in high-humidity conditions.
• Rapid Moisture Absorption – Calcium chloride actively draws moisture from the air, making it highly effective in damp basements, storage rooms, shipping containers, and industrial environments.
• Fragrance-Free – No added scents or chemicals. Safe for use near sensitive materials, documents, electronics, and food storage areas.
• Versatile Industrial & Home Use – Suitable for drying gases such as nitrogen, oxygen, hydrogen, hydrogen chloride, and sulfur dioxide, as well as general humidity control in enclosed spaces.
• Single-Use Desiccant – Unlike silica gel, calcium chloride cannot be regenerated by heating. Replace when the beads have fully dissolved or liquefied after absorbing moisture.

Perfect For

• Basements, crawl spaces, and damp storage rooms
• Shipping containers and freight transport
• Industrial gas drying (nitrogen, oxygen, hydrogen, SO₂)
• Warehouses and large enclosed storage spaces
• Refilling compatible moisture absorber units

Calcium Chloride vs. Silica Gel – Which Should You Choose?

• Calcium Chloride: Higher absorption capacity, ideal for very humid environments, single-use (not regeneratable)
• Silica Gel: Lower absorption capacity, suitable for moderate humidity, reusable after oven regeneration

Frequently Asked Questions

Can calcium chloride desiccant be regenerated like silica gel?
No. Unlike silica gel, calcium chloride cannot be reactivated by heating. Once the beads have absorbed their maximum moisture and dissolved or liquefied, they should be safely disposed of and replaced.

How do I know when to replace the desiccant?
When the calcium chloride beads have fully dissolved or turned into a liquid, they have reached their absorption limit and need to be replaced.

Is calcium chloride safe to use at home?
Yes, when used as directed. Avoid direct skin contact with dissolved calcium chloride liquid, as it can cause irritation. Keep out of reach of children and pets.

What is the absorption capacity of calcium chloride compared to silica gel?
Calcium chloride can absorb significantly more moisture than silica gel by weight — often 2 to 5 times more — making it the preferred choice for high-humidity environments.

Can I use this as a refill for existing moisture absorber units?
Yes. These beads are designed as a refill for compatible moisture absorber containers. Check your unit’s compatibility before use.
