Molecular sieves are used in sealed insulating glass units to prevent fogging. Fogging on inner glass surfaces by condensation of water and solvent vapors is common inside sealed dual pane windows. Window fogging arises when the vapors trapped between the two panes of the insulating glass unit condense on the glass surface. This is due to the lower temperature of the glass surface than the dew point of the air between the two panes.

To prevent fogging the moisture vapor concentration inside the dual-pane window must be controlled. Using this desiccant molecular sieves for insulated glass can absorb moisture more than all commercially available adsorbents and sometimes they also can remove solvent vapors. When moisture or solvent vapors are absorbed by the molecular sieves, the moisture vapor concentration in the air space is reduced and the moisture dew point of the airdrops to a lower value and no condensation can occur until the glass temperature goes below that.

We provide the best molecular sieves in the adsorption process. The sieves grant protection against moisture and water. They find use in many industries such as oil & gas, petrochemicals, sugar, and air industries. The sieves are used for many purposes including water removal, moisture removal, oxygen removal, natural gas drying, industrial gas drying, and natural gas dehydration. They are available in A and X type crystalline structure and in beads & pellets. The product type includes molecular sieve 5a, 4a, 3a &13x.
