Regenerative air dryers use desiccant media to adsorb moisture and contaminants from compressed air. The desiccant media can be regenerated, or purged of the moisture it collects, and used again and again. Our regenerative dryers use this process to allow compressed air to be dried to very low dew points of either -40°F, -80°F, or -100°F. These low dew points are necessary for critical compressed air applications or for those in extremely cold ambient conditions where any moisture remaining in the air would freeze inside compressed air system piping and block flow.
ZPB heatless desiccant air dryers deliver clean, dry compressed air for critical applications where the presence of even minimal moisture can’t be tolerated. They utilize a portion of the dried compressed air volume for regeneration of the desiccant media in a continuous drying process. Part of the ZEKS EclipseTM dryer line, ZPB models are engineered to provide the operating and service benefits needed most:
Options For Energy Savings
NEMA 4 Option
Includes a digital controller with large backlit graphical display that provides access to all dryer functions. Display of maintenance reminders and alarms assures dryers deliver consistent, uninterrupted service. This enhanced controller enables external communication via Modbus that is accessible through a RS-485 port. Integration into Distributed Control Systems (DCS) is assured with user-adjustable baud rate.
Refrigerated Air Dryers
Refrigerated air dryers remove moisture and contaminants from compressed air by chilling the air to a temperature
that causes the moisture in the air to condense and form droplets. These can be separated from the air stream and discharged from the dryer.
