Desiccant dryers are devices used to remove moisture from the air or gases. They utilize a desiccant material, such as silica gel or activated alumina, which absorbs water vapor. This process is essential in various industries, including pharmaceuticals, food processing, and electronics, where controlling humidity is crucial for product quality and safety. These dryers operate in cycles, where the desiccant material is first used to absorb moisture and then regenerated by heating or using a vacuum to release the trapped water. This efficient method helps maintain optimal conditions in storage and production environments, preventing damage and ensuring longevity of sensitive materials.
