Molecular Sieve

Dries far below the level silica gel can reach

Silica gel is excellent between roughly 30% and 90% relative humidity. Below that it gives up its water reluctantly and its capacity collapses. Molecular sieve is the opposite: a crystalline zeolite with a uniform pore size that holds tightly at very low humidity, which is why it appears in insulating glass, refrigerant circuits and gas purification rather than in cartons.

Key features

  • Types 3A, 4A, 5A and 13X
  • Gas phase 4–8 mesh; liquid phase 8–12 mesh
  • Powder forms available
  • Uniform, selectable pore size

Why customers specify it

  • Achieves dew points silica gel cannot
  • Pore size can be chosen to exclude larger molecules
  • Retains capacity at low relative humidity
