Description

4A Molecular sieve is an alkali alumino-silicate. It is the sodium form of the Type A crystal structure and has an effective pore opening of 4 angstroms. It is used to dehydrate air and gases in regenerative compressed air dryers and static drying. Molecular sieves are regenerated by heating and purging. Regeneration temperatures must be 400° to 600° F but are not to exceed 1000° F. The degree of regeneration depends on the temperature reached in purge. Molecular sieves are often used as a polishing layer for dewpoints to 120° F.

Features

  • Dewpoints Down to 100° F. and Lower: molecular sieves are often used as a polishing layer in dryers to achieve dewpoints down to 120°F. This product is the most effective desiccant for low inlet, relative humidities, generally below 30-35% RH.
  • Uniform Size = Low Pressure Drop in a packed bed, molecular sieve provides a low pressure drop which minimizes channeling and maximizes utilization of the whole drying capacity of the compressed air dryer tower.
  • Round Smooth Beads/Low Abrasion: This feature of molecular sieves also contributes greatly to lower pressure drop. Importantly, it means far less dusting, migrativion / attrition and longer life by not allowing clogging of desiccant pores.
