DESICCANT ROTOR
The Desiccant Rotor is the heart of the
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 PGD970DES 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.
