ABP Series Heated Blower Purge – Regenerative Desiccant Dryers
The Aircel ABP Series (800 – 15,000 SCFM) , which replaces the legacy HRE Series, is Aircel’s new blower purge heat reactivated dual tower regenerative air dryer. This new design comes standard with Energy Management System (EMS) for solid peace-of-mind energy savings and consistent operation. This system is controlled by an Allen Bradley PLC and a 6” LCD Color Touch Screen.
The standard Energy Management System (EMS) control 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.
Why is the ABP Series different?
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.
Aircel’s 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.
Controls & Energy Management System
The Aircel ABP Series utilizes the Allen Bradley MicroLogix 1100E PLC Controller for automatic control and flexible programming. This addition sets a higher standard of configurations and capabilities that exceeds other blower purge dryers in the market. With built-in Ethernet connection, you can access, monitor and program from any available connection. An embedded web server is also included to configure controller data easily on a web page.
