HOW IT WORKS

Your DDH2500 Desiccant dehumidifier removes moisture using a continuous-
ly rotating moisture absorbing wheel/rotor (This 'Desiccant Rotor' is literally 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 honeycomb,
of hygroscopic membranes absorb almost all of the moisture creating an
extremely dry airstream. Most of this airstream is discharged directly through
the 'Dry Air Outlet' however, a portion of this air (Regen Air) is separated and
directed 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 previously 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.

DESICCANT ROTOR
The Desiccant Rotor is the heart of the
DDH2500 dehumidifier. It is an array of specially
absorbent membranes arranged as a series of
corrugations (as shown in the cut-away image
below) to give a vast surface area making it an
extremely efficient moisture collector.
It is encases in a galvanized steel ring and turns
on high quality sealed ball bearing units.
REGEN HEATER BANK
The DDH2500 uses a ceramic PTC type regen
heater.
PTC (Positive Temperature Coefficient) heaters are
base on a semi-conductor that changes resist-
ance as it becomes hotter. The semi-conductor is
designed so that it's resistance rises rapidly at a
predesignated temperature, thus it maintains this
temperature across a wide range of operational
conditions.
This characteristic means that the heating element
can never over heat to hazardous temperatures,
even if the regen airfow is completely blocked.
FAN SYSTEM
The DDH2500 uses a patented 'RadiCal'
backward curved fan unit, this is a highly
effective yet quiet system. It is designed
to give a good balance of airflows for both
'Process' and 'Regen' airflows.
