Desiccant silica gel beads are 97% silica and 3% alumina. Silica
Gel can be used to dehydrate both compressed air and natural gas.
The desiccant silica gel bead shape, uniform particle size and high
bulk density combine to ensure optimum air/gas flow without nesting
or channeling. Minimal dusting occurs due to the hard, smooth,
spherical shape of the silica desiccant beads. Desiccant silica gel
beads are an excellent option for applications requiring long-term
economy, higher capacity, premium performance and energy
savings.
The internal structure of a silica gel granule contains a vast
network of inter-connecting microscopic pores, which attract and
hold moisture via physical adsorption and capillary condensation. A
single teaspoon of silica gel has an internal adsorptive area
equivalent to a football field. Silica Gel is inert and non-toxic.
Even when saturated silica gel looks and feels dry to the touch.
Since the second World War, silica gel has been the desiccant of
choice by government and industry.
