Dessiccant types

SILICA GEL — Finite Filter’s 100 percent indicating silica gel provides Maximum moisture adsorption and dewpoints down to -40° F.

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.

Outstanding features of Silica Gel include:

High adsorption capacity - average surface area for each bead is over 200 ft2
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

MOLECULAR SIEVE — Molecular sieves are crystalline, metallic aluminum silicates. The type 4A offers  xceptional water vapor adsorption characteristics. Dewpoints are attainable to -40° F.

Why Finite Desiccant Dryers?

Finite® desiccant dryers are the simplest and most reliable method of ensuring your sensitive pneumatic equipment is not exposed to damaging moisture. When air is compressed, the temperature of air is increased as is its capacity to hold moisture. As the hot moist air travels downstream through the pipelines, it cools, allowing the moisture to condense. Aftercoolers, Filters, drain traps and drip legs are effective for removing condensate. For removing residual water vapor and aerosols, use the Finite desiccant dryer.
