1.0 GENERAL DESCRIPTION
Hankison silica gel desiccant dryers are designed
to lower the dew point of compressed air. They
consist of a filter housing filled with silica gel
desiccant through which air passes. As the air
passes across the silica gel desiccant, moisture is
adsorbed into the pores of the silica gel, reducing
the moisture content (dew point) of the outlet
air. Once the silica gel desiccant reaches a level of
saturation that causes the outlet dew point to rise
above an acceptable level, the silica gel desiccant
can be either replaced or regenerated by baking
in an oven.
