Silica Gel

Silica gel is a spherical bread consisting of 97% silica and 3% alumina with a highly porous surface and a strong affinity for adsorbing water. Silica gel is also applied as a selective adsorbent for a wide-range of hydrocarbons, C02, siloxanes, sulfur, and many other compounds.

Because silica gel fractures in the presence of liquid water, it is often protected with a pre-bed of activated alumina.

In air and gas drying applications, dew points of -40°F and lower can be achieved with silica gel.




Features and Benefits

  • High moisture retention capacity under dynamic conditions, allowing heated desiccant dryers with a higher design capacity and lower regeneration temperature
  • A uniform bead shape provides for a lower pressure drop and less abrasion than granular types of silica gel.
  • Available in two types, non-indicating and indicating. Indicating silica gel is impregnated with a moisture indicator that changes color from blue to pink when saturated.
  • High static adsorption (moisture retention) under certain relative humidity conditions
  • Available in indicating (blue to pink) and non-indicating
  • Available in 5# pails, 25# pails, 50# bags and 330# steel drums
