Heatless Desiccant Air Dryers - TW Series



Parker TW Series Heatless Desiccant Air Dryers remove water vapor from compresses air through
a process known as pressure swing adsorption
. Pressure dewpoints ranging from -40°F (-40°C)
standard to -100°F (-70°C) optional are attained by directing the flow of saturated compressed
air over a bed of desiccant.
