Activated Alumina Ball for Dehumidifier

Dehumidification is the process of removal of water/vapors/moisture from the air. It usually takes place using three methods which involve condensation, absorption, and adsorption. Here we are dealing with the adsorption procedure using the activated alumina desiccants.

Desiccant dehumidifiers work on the principle of removing moisture from the air with the use of desiccants. Desiccants conduct moisture removal by the process of adsorption. Activated alumina is one of the finest desiccants that has the highest water absorption capacity when compared to its other counterparts such as molecular sieve, silica gel, and activated charcoal. Being the cheapest yet most effective at dehumidification, activated alumina desiccants are widely used for gas and liquid dehydration process. This naturally occurring form of aluminum oxide requires less heat for regeneration in comparison with molecular sieve.

Activated Alumina Ball for Dehumidifiers

Let’s understand how activated alumina balls are used in dehumidifiers. The activated alumina is impregnated into the paper sheets that are wrapped or wounded around a wheel or a rotor. When the air from outside also known as the processed air enters across the rotor, the moisture is adsorbed and the dry air leaves the rotor and is sent using a process fan towards the designated area. As more processed air enters the rotor, the activated alumina desiccants tend to get saturated. To conduct the reactivation process, hot air is blown across the rotor. This process transfers the moisture from the rotor into the exhaust air which is ducted outside. The temperature of the hot air blown is controlled using a gas burner. The optimum temperature of the hot stream ranges between 160 - 185 °C. Post the regeneration process, it is always essential to make sure the activated alumina ball bead is cool enough by checking the cooling outlet temperature.
