Heated Desiccant Air Dryers with Blower -40°F Dew Point (800-15,000 scfm)
The ABP Series is Aircel's new blower
purge heat reactivated dual tower regenerative air dryer with
standard Energy Management System (EMS) for solid peace-of-mind
energy savings and consistent operation automatically controlled
via an Allen Bradley PLC and a 6" LCD Color Touch Screen.
The Aircel ABP Series Dryers
(800 - 15,000 scfm) utilize a standard Energy Management
System (EMS) control that incorporates an integral air outlet dew
point sensor to continually monitor the outlet moisture content and
to display on the system color touch screen. The EMS control
extends the drying time if the outlet dew point is below a preset
adjustable set point saving a tremendous amount of energy, valve
wear and tear (less switching) during low loading conditions.
Energy saving is achieved since the overall regeneration time and
dry air cooling time is reduced. The EMS control also provides an
Outlet High Humidity Alarm.

The Compressed Air and Gas Institute (CAGI) has developed standards to protect users of compressed air & gas equipment ADF 200 is the current standard for desiccant compressed air dryers. ADF 200 specifies the dryers performance to be rated at -40°F pressure dew point, 100°F inlet temperature, 100°F ambient temperature, and 100 psig system pressure. To adjust the dryer capacity from these "CAGI conditions" to your specific application, please use the correction factors below for differing inlet air temperatures (C1) and system pressures (C2).

Why is the ABP Series different?
For added energy savings, the ABP Series uses a high efficiency blower to take in ambient air required during the heat regeneration cycle to desorb moisture from the desiccant. No compressed air is used during this phase.
Dry compressed air is used during the dry air cooling regeneration period for reduced heat and dew point spike at tower switchover. This amounts to an average process air use of 2% of the rated capacity of the dryer.
Aircels unique parallel cooling mode further reduces the heat and dew point spike prior to tower switchover. During the parallel cooling mode both inlet valves are open for a 10 minute period and divert half-load to each tower further cooling the previously regenerated desiccant bed with a larger volume of air.

How it Works
How The ABP Series Works
Pre-filtered wet compressed air enters the bottom of the on-line vessel.
Compressed air passes upward through the desiccant bed; moisture is removed, lowering the dew point to -40º F.
Dry compressed air exits the top of the vessel and flows downstream to the after-filter, monitored constantly via standard dew point sensor. This EMS feature extends the drying period until the target dew point occurs. This greatly reducing energy costs.
Prior to regeneration, saturated online vessel goes offline and depressurizes to ambient through an angle seat valve and muffler.
After the off-line vessel has depressurized, a blower draws in ambient air for regeneration.
This air passes thru an immersion heater, check valve, and enters top of regenerating vessel.
As the hot ambient air passes downward through the desiccant bed, water molecules are released from the surface of the desiccant.
Hot regeneration air passes through a butterfly valve and exhausts to atmosphere. Heating phase may terminate early due to low load conditions; this energy savings is automatically passed onto the customer and allows for earlier cooling process to begin.
At the end of the heating phase of the cycle, the desiccant bed, although regenerated, remains hot. The temperature of the bed must be lowered to reduce dew point and temperature spikes in the process air when the bed goes back on-line. This is accomplished by allowing a slipstream of dry process air, controlled by an automatic valve, to flow from the on-line vessel into the off-line vessel. This slipstream is also used to repressurize the offline vessel after it has been cooled placing the unit into standby. The EMS control continues to save by extending the drying period through outlet dew point monitoring until the target dew point is reached.
Unique to the Aircel ABP is our parallel running period 10 minutes after vessel switchover. During this period, the incoming flow of wet compressed air is directed through both vessels. This step further reduces the dew point and temperature spikes associated with heated dryers. This parallel cooling mode requires no purge air.
