CO2 Dryers are used extensively in industries like food & beverage for the removal of moisture and impurities in CO2 gas. The dryer is controlled with PLC (programmable logic controller). The equipment is specifically intended for reducing or eliminating point-of-use impurities in gases such as hydrogen, helium, methane, nitrogen and carbon dioxide. This ensures a continuous supply of clean and dry gas. These dryers are developed such that a small quantity of dry CO2 purge is generated with the regeneration of desiccant at higher temperature.
