SPX HCS Series Heatless Desiccant Air Dryers

Deltech’s HCS Series with patented SensaTherm automatically matches purge air to plant air demand. This ensures maximum performance as the saved energy goes right to your bottom line.
When operating at reduced capacity, the on-line drying tower remains active longer, until its full drying capacity is utilized. Desiccant bed temperature changes are constantly monitored within each tower to precisely manage drying times and reduce purge air consumption.
SensaTherm also measures the increase in desiccant bed temperature (heat of adsorption) during the drying stage and the decrease in desiccant bed temperature (heat of desorption) during the regeneration stage. These temperature changes are accurate indicators of the moisture load on the dryer. This data is interpreted by microprocessor based controls to determine how long a tower stays on-line during the drying stage.
