Heatless desiccant air dryers use a small portion of dried, compressed air to purge and regenerate the off-line tower. We have been engineered to ensure optimal performance and efficiency in a range of different applications while keeping downtime to a minimum.

The desiccant air dryer systems includes several models that deliver between 230 and 3,400 CFM of clean, dry air at a pressure of 100 psig. All feature a heavy-duty steel base and dual tower configuration that regenerates automatically.

Under normal operation, air is forced upwards through the drying tower, where moisture and contaminants are removed and a small amount — 15% — of air is diverted downwards through the regeneration tower where it depressurizes the desiccant bed to ambient conditions. Overall velocities are kept below 50 feet/minute so that air remains in contact with the desiccant for a minimum of 4.5 seconds. The entire process follows a 6-10 minute NEMA cycle, which consists of three to five minutes of drying time, 2 minutes and 25 seconds to 4 minutes and 20 seconds of regeneration and 40 seconds of re-pressurization.
