Desiccant Compressed Air Dryers

EHA Externally Heated Twin Tower Dryers

The nano EHA externally heated twin tower desiccant compressed air dryers are designed to remove water vapor from your compressed air lowering the pressure dewpoint to -40°F.  Designed for the most demanding environments, low-pressure drop and consistent dew point performance are key benefits of the dryer range. As the size of your compressed air system increases, it becomes more important to reduce purge air consumption. The EHA range does just that with the purge rate averaging 6 to 8% conserving compressed air and saving you money.
