• Unlike refrigeration based dehumidifiers, which chill air below its dew point to condensate the water vapor, the 1800 desiccant based systems act more like a sponge.
  • Moisture laden air is drawn through the rotor in the process air stream. The desiccant embedded in the rotor “soaks-up” this moisture and holds on to it.
  • The dried process air is ducted into the required area.
  • The rotor brings the soaked desiccant into the reactivation air stream where it is heated up.
  • The hot air “squeezes” the moisture back into the reactivation air stream as water vapor.
  • The wet reactivation air is ducted outside to the atmosphere.
  • The 1800 Desiccant simply functions as an air-to-air moisture exchanger, taking moisture out of the process air stream and placing it into the reactivation airstream.
