Molecular Sieve

Molecular Sieve

Molecular sieve is a sodium aluminosilicate. It has a fixed pore size according to the material specified, 4 Angstrom being the most common.

Because of its higher cost, it is normally used for special process applications. Pressure dew points to -100° F may be achieved with molecular sieve depending on the dryer design and operating conditions.

FEATURES & BENEFITS:

  • Uniform retention capacity: Moisture retention (pounds of water adsorbed per pound of desiccant) does not change appreciably if the air or gas is not saturated. It also keeps its moisture retention properties over a wider range of operating temperatures.
  • Round bead shape: Spheres have high abrasion resistance and results in lower pressure drop than extruded molecular sieve.
