SPECIFICATIONS
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
airstream (Regeneration Air) is heated to a high temperature before
passing over the wheel. Any moisture present in the wheel is released
into this
airstream; this hot wet air is then exhausted outside the area being
dried.
