Application Specific DesignsH OW I T WO R K SPhase 1 Moist, filtered compressed air enters the pressurized on-linedesiccant-filled drying Tower 1 through the AccuShift valve (A)Phase 2 Up-flow drying enables the desiccant to strip the air stream ofmoisture. Clean, dry compressed air exits through AccuShift valve(B) to feed the air systemPhase 3 When in regeneration mode, Tower 2 depressurizesto atmosphere through the muffler (C) when the valve(D) opensPhase 4 A portion of dry compressed air (purge air) is diverted before exiting(B) and passes through off-line Tower 2 and exits at valve (D) todesorb the moisture from the desiccant. Once desorbed, valve (D)closes and Tower 2 is repressurizedPhase 5 At tower shift-over, valve (E) will open, causing AccuShift Valves (A & B) to shiftPhase 6 Tower 2 will be placed on-line to dry the bed. Operations will switch and Tower 1 will be regeneratedM ATC H P E R F O R M A N C E BY D E M A N DThree user selectable designs engineered to balance economy and performance.Ideal for applications that operate with a large swing in air demands due to variations in production scheduling or shifts of operation.

HHS Series Desiccant DryersAU TO M AT I C S E N S AT H E R M E N E R GY S AV I N G SHankison’s HHS Series with patented SensaTherm automaticallymatches purge air to plant air demand. This ensures maximumperformance as the saved energy goes right to your bottom line.When operating at reduced capacity, the on-line drying towerremains active longer, until its full drying capacity is utilized.Desiccant bed temperature changes are constantly monitoredwithin each tower to precisely manage drying times and reducepurge air consumption.SensaTherm also measures the increase in desiccant bedtemperature (heat of adsorption) during the drying stage and thedecrease in desiccant bed temperature (heat of desorption) duringthe regeneration stage.
