Secador de aire desecante con calefacción externa de 3200 CFM Deltech

3200 CFM Externally Heated Desiccant Air Dryer Deltech

Externally Heated Desiccant Compressed Air Dryers

For decades, compressed air users have relied on Deltech to deliver technology that reduces the cost of operation and improves the reliability of air driven processes. The RP Series is engineered to deliver ISO 8573.1 Air Quality and reduce purge air consumption. In combination with our advanced Ambient Air Amplification (A3) Purge Technology TM,we offer externally heated purge desiccant dryers with dew point performance guaranteed from 250 to 3,200 scfm.

The Deltech Guarantee Deltech guarantees that RP Series dryers will produce the design dew point while operating continuously at maximum rated flow (100% duty cycle) at CAGI ADF 200 inlet standards of 100°F inlet temperature and 100% relative humidity at 100 psig.

 RP Series Dryers:  -4°F to -40°F Pressure Dew Points
Applications that simply want seasonal protection against freezing are exactly what the standard RP Series dryers are designed to address. ISO 8573.1 dew points between Class 2 and Class 3 are delivered automatically with the standard design. Class 2 (-40°F) dew points protect usage points from freezing during winter. Class 3 (-4°F) dew points keep air systems nice and dry all summer long. Applications that require Class 2 (-40˚F) dew points year round simply need to select the Jet Blower option package.

 How It Works

Standard Design:
Moist, filtered compressed air enters the pressurized on-line desiccant-filled drying Tower 1 through valve (A). Up-flow drying enables the desiccant to strip the air stream of moisture. Clean, dry compressed air exits through valve (E) to feed the air system. Tower 2 (when in regeneration mode) closes valve (B), then depressurizes to atmosphere through muffler (C). Valves (D & G) open and the heater turns on. A portion of dry compressed air (purge air) is diverted before exiting (E) and passes through the heater. Hot dry purge air desorbs the moisture from the desiccant as it flows down through Tower 2 to exit at valve (D). Once desorbed, the heater turns off and cool dry purge air continues to pass until the desiccant bed is cooled. Finally, valve (D) closes and Tower 2 is repressurized. At a fixed time interval, valve (B) will open and Tower 2 will be placed on-line to dry the bed and valves (A & D) will close. Operations will switch and Tower 1 will be regenerated.
