Desiccant air dryers

ECOTROC DDN DESICCANT DRYERS HEATLESS REGENERATED

KSI

Pressure dew point down to -40°F

Capacity up to 705 cfm

Desiccant dryers are used in environments where a specified pressure dew point of -40°F to -94°F must be reliable and safe. Dryers of the ECOTROC DD series are available in three versions: as a compact aluminum series (DDAP) for volume flows up to 110 cfm, with welded vessels (DDN) for volume flows up to 705 cfm as well as in the large version (DDF) up to 1800 cfm*. Higher volume flows are available on request.
