CO2-R-DRY 400-20000 BP adsorption dryers are designed for the continuous separation of water vapour from compressed CO2, thereby lowering the dew point. CO2-R-DRY dryers have two columns that operate alternately. Adsorption takes place under pressure in the first column while the second column regenerates (heated ambient air for desorption + purge of dry expanded CO2 for cooling). A dryer consists of two columns filled with desiccant balls, a fan, a heater, a controller with LCD screen, valves, pressure gauges and a steel frame. Its proven, robust design ensures efficient, reliable operation, rapid installation and simple maintenance.
