Aquasorb  (Deliquescent Dryers)

Product Information:
  • Formulated dehydration product to remove water vapor from compressed air, natural gas, and other selected gases and organic liquids.
  • Comprised of two primary chemical compounds: sodium chloride and hygroscopic agent.
  • Sodium chloride serves as an extender for the hygroscopic compound and reduces it's tendency to bridge and channel.
  • The hygroscopic compound controls the ultimate level of moisture removal (absolute dewpoint or relative humidity).
  • Both the sodium chloride and hygroscopic compound contribute to bulk water removal.

Product Information:
  • 4-8 mesh.
  • Used for dehydration, but is generally used as an indication determining a dewpoint in an air or gas stream.
  • A dry sample will indicate blue.   As the dewpoint increases the color changes to pink, then white.
  • "White" indicates the gas is saturated with water.
