Blower Purge Dryers

 

Specifications:

Model: KBD Series
Flow rate: 500 to 4300 scfm
Pressure dew point to: -40°F

KBD blower purge dryers

Kaeser externally heat-regenerative blower purge desiccant dryers produce dew points as low as -40°F. Twin desiccant beds of activated alumina alternate between drying and regenerating, with regeneration being accomplished with heated ambient air at just above atmospheric pressure. The heated ambient air readily drives adsorbed moisture off of the desiccant preparing the it for another adsorption cycle. The moisture-laden regeneration air exhausts to atmosphere during the regeneration process. KBD dryers can regenerate with little (about 1%) or no process (purge) air loss.

Solid state logic accurately controls inlet and purge valves which direct wet compressed air to the regenerated tower, and heated ambient air to the tower in need of regeneration. The process of adsorption and desorption can be repeated several thousand times before the desiccant must be replaced.     


Advantages:
  • Outstanding energy savings by heating atmospheric air for regeneration and using no purge air
  • Reliable controls and instrumentation meet NEMA 4 standards 
  • Color change moisture indicator signals elevated dew point
  • ASME pressure relief valve

 


  

Heated Purge Dryers

 

Specifications

Model: KED Series
Flow rate: 300 to 3200 scfm
Pressure dew point to: -40°F

KED desiccant dryer

Solid state logic accurately controls inlet and purge valves which direct wet compressed air to the regenerated tower, and heated purge air to the tower in need of regeneration. The process of adsorption and desorption can be repeated several thousand times before the desiccant must be replaced.


Advantages:
  • Excellent energy savings by using only 7% purge air for regeneration
  • Reliable controls and instrumentation meet NEMA 4 standards 
  • Color change moisture indicator signals elevated dew point
  • ASME pressure relief valve
