The '''Regens''' are used for drying air in  [[Storage Tanks]] or [[Pneumatic Conveying Systems]] and are beneficial in the drying of  hygroscopic  (water-absorbing) resins. These [[Dryers]] remove water from  the air by  passing it through a desiccant that absorbs moisture.

Heated purge regenerative Regens use less air than the heatless variety in addition to heat, which helps the air carry away more water as it  passes through the saturated desiccant.

Using  Pressure Swing Adsorption (PSA) technology, the Twin Tower Engineering  regenerative air dryers are designed to maximize the efficiency of the  drying process. Ultra-Dry compressed air dew points of -40°F to better  than -100°F can be achieved.
===Large Heatless Regens===
Engineered  for long service life and superior protection of your air-operated  equipment and processes. THL series heatless regenerative desiccant  compressed air dryers deliver the peace of mind of high quality, value  and fast delivery.
===Compact Heatless Regens===

Economical  and compact, these heatless desiccant compressed air dryers provide  low  dew points to -100°F ADP(atmospheric dew point). This proven  "no-frills" design uses Pressure Swing Adsorption (PSA) technology and  will provide years of trouble-free service.
===Mini Heatless Regens===

Ultra-small  desiccant compressed air dryers can be used for low-flow applications or with fractional horsepower air compressors. These units are heatless  regenerative Regens designed to produce low dew points.  Extremely small footprint allows for packaging inside equipment  cabinets  or at point-of-use.
===DMD Desiccant Modular Dryer===
[[File:DMD_Desiccant_Modular_Dryer.jpg|thumb|right|200px|DMD Desiccant Modular Dryer]]
A  small  amount of the dried compressed air is used to regenerate the  saturated  desiccant bed by expanding air from line pressure to  atmospheric  pressure, removing the moisture absorbed by the desiccant  material.  Protection is built-in. Extruded aluminum housings that  surround the  dryers are fully protected from corrosion.
===DHL Desiccant Heatless Dryer===

The dual tower design of the DHL dryers allows for continuous absorption of water from compressed air by using a desiccant bed. Drying  is accomplished by passing wet compressed air through the desiccant  bed  of one tower where moisture is absorbed. Regeneration of the  desiccant  is accomplished without the use of heat. The wet bed is dried  by  diverting a small amount of dry air from the outlet at near  atmospheric  pressure. The purge flow rate is adjustable to suit the  desired dew  point. The dry air flows in a counter direction through the  wet bed,  sweeping all the water vapor previously absorbed by the  desiccant.
===DEX Desiccant Externally Heated Dryer===
[[File:DEX_Desiccant_Externally_Heated_Dryer.jpg|thumb|right|200px|DEX Desiccant Externally Heated Dryer]]
The dual tower design of the DEX dryers allows for continuous absorption  of  water from compressed air by using a desiccant. Drying is  accomplished  by passing wet compressed air through the desiccant bed of  one of the  towers where moisture is absorbed. Regeneration of the  desiccant is  accomplished with the use of a low watt density heater.  The heated air  has a greater affinity to absorb moisture. When passed  through the  regenerating tower at near ambient pressure, the heated air  flows in a  counter direction through the wet bed, removing moisture  previously  absorbed by the desiccant.
===DBP Desiccant Regenerative Blower Purge Dryer===
[[File:DBP_Desiccant_Regenerative_Blower_Purge_Dryer.jpg|thumb|right|200px|DBP Desiccant Regenerative Blower Purge Dryer]]
The  dual tower design of the DBP, blower purge dryer, allows for  continuous  absorption of water from compressed air by using a  desiccant. Drying is  accomplished by passing wet compressed air through  the desiccant bed of  one of the towers where moisture is absorbed.  Regeneration of the  desiccant is accomplished using a blower to pass  ambient air through a  low watt density heater because heated air has a  greater affinity to  absorb moisture. When passed through the  regenerating tower at near  ambient pressure, the heated air flows  through the wet bed, removing  water vapor previously absorbed by the  desiccant.
