Molecular Sieves for Industrial Applications



Molecular sieves are high-performance desiccants characterized by a microporous structure with uniform pore sizes. Unlike traditional desiccants like silica gel, which have irregular porosity, molecular sieves offer precise selectivity due to the consistent size of their pores: each type allows only molecules smaller than a certain size to pass through, selectively retaining larger ones.


This property makes them particularly suitable for industrial applications that require efficient molecular separation, moisture removal from gases and liquids, and purification of gas streams. Common areas of use include the treatment of technical gases (such as oxygen, nitrogen, hydrogen, and CO₂), dehumidification of compressed air, and process plant operations in the chemical, petrochemical, and pharmaceutical sectors.


We offer 4Å (ångström) and 13X molecular sieves in standard 2–5 mm particle size and a wide range of packaging options, from small canisters and medium to large drums, to big bags. Upon request, we can also supply different particle sizes or specific pore sizes based on application needs.
