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
