Drytech has developed a range of molded and immobilized desiccants. These products are molded and shaped using a variety of desiccants including molecular sieves and activated aluminas. Organic binders are used in the blending process of molded desiccants to arrive at a net shape molded product providing a robust form similar to that of a thermoset plastic. Organic binders are used in the blending process of immobilized desiccants to arrive at a housed but immobilized or sintered bed. Both processes utilize heat, pressure and vacuum.

Typically immobilization requirements are for extremely harsh vibration environments. One of the byproducts of this process is that it can provide adsorption maximization by retarding flow through the bed, thus allowing the moist air to dwell over the desiccant longer.
Unit of Measure



  • Adsorption capacity up to 22% of dry weight at 70°C at 95% RH
  • Retarding factor/adsorption efficiency increase up to 150% of normal bed.
  • Density: Approximately 800 grams/liter
  • Vibration capability: To MIL-STD-8 10 Method 514.3, 10-2000 Flz and 27 grams, X,Y, Z axis.
  • Method: Heat sintering w/polymeric binders



  • Tolerates high vibration & shock environment without attrition of the desiccant bed.
  • Increases gas to desiccant contact time thus increasing adsorption of water vapor, CO2 or other gases by selective adsorption.
