The Twin Tower Engineering CAS-Series carbon dioxide adsorbers are designed to remove CO2 from compressed air for outlet flows up to 320SLPM (11.3 SCFM). The carbon dioxide adsorber does this by using media beds featuring 13X molecular sieve in a pressure swing adsorption process for a more efficient adsorbtion of CO2. Outlet CO2 levels less than 1 PPM; outlet H2O levels less than -100°F dew point. Adsorbed moisture and CO2 are vented to atmosphere while dry CO2 free air is provided at the outlet port. | The Twin Tower Engineering CAS-Series carbon dioxide adsorbers are designed to remove CO2 from compressed air for outlet flows up to 320SLPM (11.3 SCFM).

The Twin Tower Engineering VCD-Series carbon dioxide adsorbers are designed to remove CO2 from compressed air for outlet flows up to 99 SLPM(3.5 SCFM). The carbon dioxide adsorber does this by using media beds featuring 13X molecular sieve in a pressure swing adsorption process for a more efficient adsorbtion of CO2. Outlet CO2 levels less than 1 PPM; outlet H2O levels less than -100°F dew point.

The Twin Tower Engineering MCA-Series Carbon Dioxide Adsorber/Dryers use the pressure swing adsorption method of CO2 removal and drying compressed air. This requires two identical towers containing beds of 13X molecular sieve beaded media. | The Twin Tower Engineering MCA-Series Carbon Dioxide Adsorber/Dryers use the pressure swing adsorption method of CO2 removal and drying compressed air.

Incoming compressed air enters the adsorber/dryer through the four-way solenoid valve, where it is directed to the bottom of the tower containing active 13X media (T1). The media in this tower removes CO2 to less than 2 ppm and 99.9+% of the water vapor from the air when operated at catalog conditions. The dry, CO2 free air leaving the top of the tower (T1) is directed to the outlet through a shuttle valve. The purge orifice allows a portion of the dry, CO2 free air to flow into the other tower (T2) being regenerated. This cleaned purge air regenerates the desiccant by removing the accumulated CO2 and water vapor and carrying it out the open purge port. | Incoming compressed air enters the adsorber/dryer through the four-way solenoid valve, where it is directed to the bottom of the tower containing active 13X media (T1).

The 4-way solenoid valve is controlled by a solid state timer. After 30 seconds, the desiccant in tower T2 is regenerated, and the timer de-energizes the solenoid valve causing the process to instantly reverse, with tower T2 adsorbing and tower T1 regenerating. | The 4-way solenoid valve is controlled by a solid state timer.
