G3MA Passive Desiccant Dehumidification Wheels Patented

Achieve Optimum Dehumidification Without energy usage

Regenerates desiccant without additional energy usage

The unique G3MA "Passive" Desiccant Dehumidification Wheel (Patented) has the ability to be regenerated with the 50% RH room return air allowing for substantial moisture removal through dehumidification of the fresh air being supplied to the room.

  • Average removal around 14 gr/lb
  • High-performance in-situ synthesized desiccant (wheel)
  • Fully water washable
  • 100% non-flammable
  • Removes moisture from a saturated air stream without heat / thermal regeneration
  • No washing away of desiccant on continued exposure to saturated / wet air

''EcoDry'' Desiccant Rotors

  • The desiccant honeycomb rotor media shall be adsorbent, non toxic, non flammable, fully water washable. The substrate of the rotor shall not be made from asbestos or any synthetic material, and shall not have any toxic desiccants impregnated like lithium chloride, etc.
  • The desiccant media shall be pH natural
  • The desiccant media shall have in-situ synthesized metal silicate desiccant on an inert inorganic fiber substrate
  • The active desiccant material shall be at least 80% of the media weight, so as to ensure high performance and minimal heat carryover
  • The net organics in the honeycomb media shall not exceed 2%
  • The desiccant rotor shall have integral long-life bearings supported by a simple fixed shaft design to allow a simple slide out of the rotor/bed
  • The desiccant dehumidification media shall have a perimeter flange which should encircle the entire perimeter so as to allow greater durability and to roll the rotor on the ground, without damage. The perimeter flange should be smooth and consistent to serve as a perimeter seal surface, thus ensuring a long life for the perimeter seal, without being cut, torn, or otherwise damaged
  • The desiccant rotor shall have a perimeter flange and shall have "teeth" located around the perimeter, to ensure a positive and slip-free rotation with a chain drive mechanism
  • The desiccant media shall not fracture due to repeated temperature and moisture cycling and all the materials of construction shall be non-toxic
  • The surface of the media shall have a special edge hardening so as to ensure a smooth surface and long life of both the media and the seal contacting it
  • The desiccant media shall not use any organic burn-off process, as this shall weaken the media structure
  • The desiccant rotor shall have a long life with adequate air filtration
