JDB SERIES

Blower Zero-Loss Desiccant Air Dryer

Moisture can be a real problem in a compressed air system.
The air outlet temperature of a compressor/after-cooler package is typically 24 – 50℃ and saturated with water vapor, which results in significant amounts of liquid downstream.
The moisture compressed air system can cause serious problems ranging from products spoilage to equipment malfunction, thus making an air dryer is a critical component in any compressed air system.
Our JDB series compressed air dryer reduces the concentration of water vapor and decreases the pressure dew point of the air to -40℃. (Optional: -73℃)
JDB Compressed air dryers use porous materials (desiccants) to adsorb moisture from the compressed air.
For regeneration, heated ambient air is used instead of expensive purge air to desorb moisture from the regenerating bed No purge loss means DRYER-IN is almost same as DRYER-OUT.

Operating Fundamental

 

  • No purge air loss and no dew point spike: Regeneration is carried out by means of heated ambient air. Therefore no purge air is used, so dryer “in” is dryer “out”. Pressure dew point and outlet temperature of the dried compressed air will not exceed the specified conditions (no peaks during switch-over), due to the special regeneration system, co-current cooling and parallel drying.
  • Low power consumption: The electrical energy consumption is matched to actual moisture loading of the desiccant. As the required heat for regeneration is equally distributed over the desiccant bed, no “hot spots” can occur, and excessive aging of the desiccant will be avoided.
  • Compact and maintenance friendly: The regeneration heater is 2-stage with thermostatic control of the second stage and it includes a safeguard against overheating. Pressurization and depressurization before and after regeneration is a part of the dryer cycle. This prevents damage and wear and tear to the valve seals and any reduction in life-time of the desiccant due to pressure shocks.
