HOW IT WORKS

Your Pridiom Desiccant dehumidifier removes moisture using a continu-
ously rotating moisture absorbing wheel/rotor (This 'Desiccant Rotor' is liter-
ally a 'honeycomb' of extremely hygroscopic membranes). A highly efficient
yet low noise fan draws air into the unit (Process Air) and forces it through a
portion of the absorbent rotor. As the air passes through the rotor, the honey-
comb, of hygroscopic membranes absorb almost all of the moisture creat-
ing an extremely dry airstream, this airstream is discharged directly through
the 'Dry Air Outlet'. A second fan pushes a separate air stream (Regen Air)
through a heater bank (Regen Heater) where it's temperature is raised. This
air is then channelled back through a section of the rotor . As this air passes
back through the membranes, its higher temperature drives-out the previ-
ously absorbed moisture and discharges it as warm wet air through the 'Wet
Air Out' duct. As the wheel rotates, this process of collecting and discharging
moisture is continuous.
