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.
