The article presents information on desiccant dehumidification. The dictionary defines dehumidification as the process of removing atmospheric moisture, and there are three ways to accomplish the task; by increasing the total pressure or compressing the air by cooling the air to condense the water vapor, and by introducing a desiccant material into the airstream. The specific dehumidification capabilities of cooling systems become more complex as the temperature is lowered in order to get more moisture removal. Therefore, cooling systems frequently give way to desiccant dehumidification in applications in which it is necessarily to dry air below 40 degree Fahrenheit dewpoint.
