SDA Series

SDA Series High Capacity Dryers

SDA Series High Capacity Dryers feature twin plenum chambers in each tower for even airflow across desiccant beds.

The SDA Series dryer is built around a user-friendly control platform designed to meet the most demanding applications.  The unit provides a compact frame with minimum moving parts, easy accessibility for maintenance, and a small footprint. Optimal desiccant utilization guarantees the lowest dew point.

Skid mounted construction lowers rigging, installation, and maintenance costs.  Every dryer is factory-tested before shipment to assure reliable performance for years to come.
