Product Description
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 25lb pails, 50lb bags and 330lb steel drums
