High Capacity Dryer

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

The 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 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.
