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.


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.
