Activated Alumina Desiccant
Activated alumina desiccant is a spherical form of activated alumina produced through a special process. It is non-toxic, odorless, non-powdering, insoluble in water, and has a strong water adsorption capacity. Activated alumina exhibits strong affinity and serves as an efficient desiccant that is non-toxic and non-corrosive. Under specific operating and regeneration conditions, it can achieve a drying depth down to a dew point of -70°C, making it suitable for deep drying of trace water.
