Silica Gel Blue Indicating 1–3 mm Beads – 55 lb Bag

1–3 mm blue indicating silica gel beads remove moisture from air, gas, and enclosed spaces in equipment designed for this smaller bead size. Supplied in a 55 lb bag, the beads change from blue when dry to pink as they adsorb moisture.

How It Works

Silica gel captures water vapor within its porous structure through adsorption. A cobalt chloride moisture indicator gives the dry beads their blue color and causes them to turn pink as moisture accumulates.

Features & Benefits

• 1–3 mm beads for equipment requiring a smaller desiccant size
• Blue-to-pink color change provides visible moisture indication
• High moisture adsorption capacity
• Can be regenerated according to the desiccant supplier’s instructions
• 55 lb bulk bag for refills and maintenance inventory

Common Uses

Used in compatible desiccant breathers, moisture-control cartridges, enclosed equipment, and air or gas drying systems specifically designed for 1–3 mm silica gel beads.

Installation & Maintenance

Confirm that your equipment requires 1–3 mm beads before refilling. Bead size affects airflow and media retention, so do not substitute this smaller grade for larger beads without equipment manufacturer approval. Follow the specified fill quantity and loading instructions.

Protect the media from liquid water and oil carryover. Keep unused beads tightly sealed in a dry location, and monitor the color change alongside equipment performance. Regenerate or replace the desiccant according to the supplier’s instructions.

Handling Precautions

Contains cobalt chloride. Do not use in direct contact with food, pharmaceuticals, or other products intended for consumption. Follow the product Safety Data Sheet for handling, protective equipment, and disposal.

Why Choose This Silica Gel?

This 1–3 mm blue indicating silica gel provides moisture removal and visible condition monitoring for equipment that requires smaller beads. The 55 lb bag offers a convenient bulk supply for refilling compatible cartridges, breathers, and drying systems.
