PCRX Series High Capacity CO2 Adsorbers

For Dry, CO2-Free Air to 4 SCFM

 

PCR CO2 Adsorbers


Compact, regenerative high capacity CO2 adsorbers capable of delivering up to 4 SCFM (115 lpm) of dry, CO2-free air at a dew point of -100ºF (-73ºC) and a CO2- content of less than 1 ppm. Ideal for FTIR spectrometer purge and emissions monitoring applications. Units come standard with an inlet particulate filter, inlet coalescing filter, purge mufflers, wall-mount bracket and outlet filter/regulator assembly. Accessories include a moisture indicator, flow meter, and surge tank.

Product Features

  • CO2-free air to less than 1 ppm

  • Environmental chambers
  • Analytical instruments and controls

The CO2 Adsorber employs Pressure Swing Adsorption (PSA) technology to remove water vapor & CO2 from ordinary compressed air. The inlet (lower) shuttle valve directs the wet air into one of the two desiccant chambers where the water vapor & CO2 is removed. The ultra-dry, CO2-free air leaving the desiccant chamber passes through the outlet (upper) shuttle valve to the application. Both shuttle valves contain a wafer-like disk, which “shuttles“ back and forth in the valve body based on the pressure differential created by the position of the two-way solenoid valves. A precision orifice in the outlet shuttle disk allows a portion of the purified air leaving the desiccant chamber to be redirected back through the off-line tower, purging it of the accumulated moisture & CO2. The purge stream exits the unit through the open solenoid valve directly below the chamber being regenerated. A solid-state timer controls the process by opening and closing the solenoid valves.
