AirCel Desiccant & Refrigerated Air Dryers

The Aircel ABP (800 - 15,000 scfm) 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.

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.

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.

The Aircel Ultrapac 2000 Series Dryers (3 - 60 scfm) purification system includes a prefilter, dryer, afterfilter, control system, and automatic condensate drain and silencer. The prefilter retains solids and condensate (oil/water mixture) up to residual oil content 0.03 ppm. The adsorption dryer next in line adsorbs the moisture in the compressed air up to a pressure dew point of -40°F. Finally, in the afterfilter, remaining particles from the drying agent are retained.

Regenerative compressed air dryers use desiccant to adsorb water vapor from the compressed airstream. In the twin tower design one tower dries the air from the compressor while the desiccant in the other tower is being regenerated to provide continuous operation. These dryers are typically referred to as "heatless" or "heated". Heatless dryers do not use any source of heat for regeneration other than the heat given off during the drying phase. This is known as the "Heat of Adsorption". Heated dryers, on the other hand, utilize an external heat source for regeneration and require little or no process air.

The Aircel Oilfreepac Purification System (50 - 5,000 scfm) removes water, oil and dirt particles from your compressed air in one process for clean, oil-free and odor-free air. It is an efficient and reliable heatless compressed air purifier providing an outlet dewpoint of either -40°F or -100°F (Optional). The Oilfreepac system filters oil and adsorbs oil vapor so thoroughly that the residual oil content is below normal detection limits, 1000 times more pure than the normal atmospheric air that we breathe.

The Aircel VF Series (10 - 1,200 scfm) offers the highest efficiencies at varying flow conditions in a lightweight, compact design. No other dryer in the industry can offer the efficiency ratings achieved by the VF Series dryers in variable flow operation. VF Series dryers are built with the patented Variable Flow heat exchanger, which allows for desired dew point performance regardless of flow variations. Typically, other dryers with mechanical moisture separators lose performance as compressed airflow velocity increases or decreases substantially around the nominal design point.

The VF Series high efficiency heat exchanger utilizes a three-step process to thoroughly remove condensed moisture from the chilled compressed air. This process provides separation efficiency in excess of 98% throughout the dryer's entire flow range. Our VF non-cycling range is focused on reliable, constant dew point performance in all flow conditions. With its excellent heat transfer coefficients and low-pressure drop, these dryers will outperform the competition in protecting your compressed air system, machinery and tools; and will improve your manufacturing processes.

The Aircel DHT (20-125 scfm) high inlet temperature refrigerated air dryers are designed for air-cooled reciprocating type air compressors, this compressed air dryer combines an oversized refrigerated circuit, high-efficiency heat exchangers and separator into a single compact unit, with single point air in/out, drain and electrical connections.

These dryers can accept compressed air up to 205°F and provide clean dry air at the outlet. Our high inlet temperature refrigerated dryers have been designed specifically for use with smaller reciprocating air compressors that typically do not incorporate an aftercooler.

The Aircel RTM Series (2,500 - 30,000 scfm) high-capacity cycling refrigerated compressed air dryers use multiple compressors with defined loading/unloading capacities and a thermal mass storage medium for energy-efficient operation. The refrigeration system cools the thermal mass medium to a predetermined lower temperature. Once that temperature is reached, the system goes into standby mode until the temperature rises to another predetermined set point.

Only then does the system come out of standby mode and once again cools the thermal mass medium. No energy is wasted when demand on the dryer is low. These dryers are ideally suited when large air volumes need to be dried to a reliable and constant dewpoint.
