Externally Heated Regenerative Desiccant Dryer
The Aircel AEHD (150 – 3,000 scfm) Externally Heated Desiccant Compressed Air Dryer is a fully automatic, PLC controlled, self-contained unit offering a fail-safe design – in the event of power interruption and/or air loss, the purge exhaust valves close preventing damage to the dryer and the process. The combination of 1) high moisture capacity, premium grade, high crush strength activated alumina used in 2) optimally sized ASME code desiccant towers providing low velocity and high contact time through the adsorbent beds delivers long service life and consistent performance.
All Aircel dryers are designed to give our customers the best value available in the industry – reliable performance to CAGI ADF 200 specification while consuming the lowest amount of energy possible.
The Aircel AEHD Series Dryers (150 – 3,000 scfm) utilize process air for regeneration of the desiccant bed similar to the heatless designs. However, this expanded process air is heated prior to entering the off-line bed, significantly reducing the required consumption and the cost of operation. Additionally process air is consumed during depressurization of the offline desiccant tower. In total these functions amount to an average process air use of 7% of the rated capacity of the dryer.
