OBSOLETE: Regenerative Desiccant Dryers - P3TJA (3-20 SCFM)
Brand: Parker HannifinP3TJA Series Heatless Regenerative Desiccant Dryers are ideal for critical, high quality, oil free air treatment applications where very dry air is required.
These dryers typically provide pressure dew points of -40°F (-40°C) down to -100°F (-73°C) pressure dew point (pdp).
Beneficially, a pressure dew point of -15°F (-26°C) or better will not only prevent corrosion, but will also inhibit microorganisms within the compressed air system.
Heatless adsorption or desiccant dryers remove moisture by passing air over a regenerative adsorbent material which strips moisture from the air.
This process is known as Pressure Swing Adsorption.
Dryers of this type are extremely efficient and provide typical pressure dew points of -40°F (-40°C) or -100°F (-73°C) pdp.
This means that for water vapor to condensate into a liquid, the air temperature would have to drop below -40°F (-40°C) to -100°F (-73°C) respectively.
Note that the actual air temperature after an adsorption dryer is not the same as its dew point.
The desiccant material is contained in two separate but identical pressure vessels, commonly referred to as "twin" towers.
As the saturated compressed air flows up through the "on line" tower, its moisture content adheres to the surface of the desiccant.
The dry compressed air is then discharged from the chamber into the distribution system.
An onboard solid state controller automatically cycles the flow of compressed air between the towers.
While the "on line" tower is drying, the "off line" tower is regenerating.
Regeneration, sometimes referred to as purging, is the process by which moisture accumulated during the "on line" cycle is stripped away during the "off line" cycle.
As low pressure dry purge air flows gently through the regenerating bed, it attracts the moisture that had accumulated on the surface of the desiccant during the drying cycle and exhausts that moisture laden air to atmosphere.
