APPLICATION
Dehumidifiers are required wherever there is a need to lower the humidity level to prevent corrosion, mold
growth and condensation or maintain a low humidity condition during manufacture, packaging or storing of
hygroscopic products.
METHODS OF DEHUMIDIFICATION
Dehumidification is possible using two possible principles, Condensation with refrigeration style
dehumidifiers and Adsorption with desiccant dehumidifiers. Desiccant dehumidifiers perform exceptionally
well when used in cooler climates, or when a low dew-point, deep drying or low humidity levels are
required. Since desiccant dehumidifiers do not produce water, they will work effectively down to sub zero
temperatures.
Their operation is simplistic yet extremely effective and
reliable. Air (Process Air) is drawn into the dehumidifier,
where is passes over a wheel impregnated with Silica
Gel. As the air passes over this wheel, any moisture
present in the air is absorbed into the Silica Gel wheel
before leaving the dehumidifier as warm dry air.
The Silica Gel wheel is continually, slowly rotating,
typically at three revolutions per hour. As the wheel
rotates, a small portion passes through the regeneration
segment. During this phase a second air stream
(Regeneration Air) is heated to a high temperature
before passing over the wheel. Any moisture present in
the wheel is released into this
air stream; this hot wet air is then exhausted outside the
area being dried.

HOW A DEHUMIDIFIER WORKS
Process air is drawn into the
dehumidifier.
Process air passes over a wheel
impregnated with silica gel.
The silica gel absorbs the
moisture from the air.
Process air leaves the dehumidifier
as warm dry air.
The silica gel wheel continually rotates.
Regeneration air is heated to a high
temperature and passed over a
segment of the wheel.
Silica gel releases the moisture from
the wheel into the regeneration air.
