100 percent indicating silica gel provides maximum moisture adsorption and dewpoints down to -40°F. Outstanding features of Silica Gel include:
- High adsorption capacity – average surface area for each bead is over 200 ft.
- Low abrasion, due to high mechanical strength for long service life
- Ideal packing in bowl due to bead shape
- Uniform color change
- Excellent regeneration characteristics
As the silica beads adsorb moisture, they change from blue to pink, indicating the need for replacement or regeneration. The desiccant can be regenerated by heating in a drying oven to a temperature higher than 212°F but not over 350°F. Desiccant may also be regenerated in microwave ovens.
