The flow of compressed air
  • 1 When the hot compressed air discharged from the air compressor enters the dryer, the first cooling is performed at the after cooler, and condensate and impurities are removed through the pre filter/separator.
  • 2 The primary cooling air is cooled by the secondary precooling while heat is exchanged with the cooled air at the heater (the pre-cooler) in the plate heat exchanger, and then cooled to the dew point by refrigerant in the evaporator.
  • 3 Fully cooled air flows through the separator to discharge condensate, and heat is exchanged with the hot inlet air inside the re-heater, to reduce the relative humidity.
  • 4 Dehumidified air is then drained from the dryer after the residual oil is removed from the after filter.
The flow of Refrigerant
  • 1 The refrigerant is compressed in the refrigeration compressor and then cooled in the condenser, depressurized and expanded in the expansion valve and then sent to the evaporator.
  • 2 Compressed air is cooled within the evaporator and the vaporized refrigerant is drawn into the refrigeration compressor.

Operating fundamental

  • 1 Compressed air enters the dryer and is directed to vessel 1 by valve and then to the dryer outlet through shuttle valve. A portion of the dried air is throttled to near atmospheric pressure by means of orifice.
  • 2 This extremely dry, low pressure air flows through and regenerates the desiccant in vessel 2 and is exhausted through purge/repressurization valve and exhaust muffler to atmosphere.

JDB SERIES

Blower Nonpurge 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.

Product Features

  • Reliable pressure dew point
  • Energy saving

  • Easy maintenance
  • ASME standard

Operating fundamental

  • 1 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.
  • 2 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.
  • 3 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.

JEF SERIES

Regenerative Circulation Desiccant Air Dryer

The hot inlet air generated from the air compressor is immediately disconnected, heated to the heater and used for the regeneration of the sorbent, resulting in a substantial reduction in heater capacity versus blower type products, and reduced electricity energy.
It is an energy-serving product without purge air loss due to its structure being recycled using heat and circulating within a closed circuit.

Product Features

  • Heat from compressed air reduces heater capacity drastically.
  • High-efficiency energy saving dryer
  • Closed system without purge air used during regeneration

  • Customizable to meet your customers ‘ needs
  • With the latest Jemaco New Controller (J-CON S), 7 ” Full control Touch Screen, Dryer Fully Automated Control
  • Energy trading system (optional)

Operating fundamental

  • 1 Regeneration
    The hot, compressed air drawn from the compressor is disconnected from the inlet or outlet of the aftercooler for dehumidification purposes of 70 % and the remaining 30 % for regeneration (heating and cooling). The compressed air produced by the compressor is reused for dehumidification, so all compressed air flow is used.
  • 2 Heating
    The hot air, isolated from the aftercooler, is heated through the heater before it enters the regenerating vessel to heat and regenerate the absorber. The moist air then cools in the regeneration cooler and passes through the water separator. It is then moved into the vessel on the other side under regeneration.
  • 3 Cooling (Regeneration)
    When the heated container is started to cool, the cooled air from the outlet of the aftercooler enters the vessel and cools the sorbent.
    This allows the discharged air to cool once again at the regeneration cooler and pass through the water separator into the vessel being de-humidified.
  • 4 Vessel Change
    After cooling, the vessel is ready for standby, wait for the set time to elapse (or until the optimal transition point is determined in Dew Point Meter & Demand Control), and then switch back to dehumidification.
