Desiccant Air Dryers | EcoDry EDB Series

Description

Parker EcoDry EDB Series Blower Purge Desiccant Air Dryers

Parker EcoDry EDB and Blower Purge Desiccant Air Dryers use the adsorption method to remove moisture from compressed air. Nominal pressure dew point reach -40°C (-70°C as option) by directing the flow of saturated compressed air over a bed of desiccant.

Parker EcoDry EDB dryers contain 2% purge air type and zero purge air type. 2% purge air type dryers combine heat with either a small portion of the dry compressed air or with forced ambient air for regeneration. Zero purge air type dryers only use ambient air for regeneration. The heated, low pressure air flows gently through the regenerating bed, stripping the moisture that accumulated on the surface and inner pores of the desiccant during the drying cycle and exhausting it to the atmosphere.

Complete Air Treatment

Without proper filtration, desiccant air dryers will not work. Desiccant dryers are designed to adsorb vapor from compressed air; they are not designed for liquid. When liquid, especially oil, is allowed to enter the desiccant chamber, it coats the desiccant material preventing any further adsorption. Oil coated desiccant can not be regenerated, and must be replaced.

The coalescing pre-filter is installed at the dryer inlet. It protects the dryer by removing liquids and reducing the contamination level of the compressed air to .01 PPM by weight.

To protect downstream equipment from desiccant dust a particulate after-filter is installed at the dryer discharge. The after-filter element is designed to remove solid particulates from compressed air.
