AEHD Series of externally heated desiccant air dryers from Aircel range in size from from 150 to 3,000 scfm. With its energy saving capabilities, the AEHD Series of externally heated desiccant dryers combine efficiency with technology to meet the needs of an application. Heated process air regenerates the towers, requiring less purge air overall (about 7% the total rated capacity of the dryer).
The standard design delivers ISO Quality Class 2 air (-40° F / -40° C) dew point to protect against freezing during low ambient conditions.
For ease of installation, ultimate dryer protection, and downstream process protection, the AEHD Series comes complete with standard installed filtration package. This filtration package includes a coalescing pre-filter with automatic drain and outlet particulate after filter with manual drain.
The AEHD Series dryers come standard with the Aircel Energy Management System — a technology that uses desiccant bed humidity sensing to maintain dew point and provide energy savings. This Energy Management System or demand cycle control system reduces purge air and optimizes dryer performance by monitoring the moisture at the mid portion of the tower desiccant bed. This allows for quick response to moisture changes while maintaining the low outlet dew point.
The control system automatically adjusts the regeneration cycle, maintaining outlet dew point and extending the drying cycle during periods of lower loading. Switching is less frequent, reducing dryer maintenance and fully utilizing desiccant capacity. This addition improves reliability and performance while sustaining the low outlet dew point. The end result is an overall purge reduction and significant energy savings.
