Wisesorb 7.5 lb Activated Alumina Desiccant Beads - Industrial Bulk Moisture Absorber

Activated alumina utilize premium quality raw material with an extremely porous structure and high surface area-to-mass ratio, high strength against crushing and very stable physical and chemical characteristics, even in high temperature and corrosive environments. At 77℉/25℃, RH90%, it can absorb more than 30% of its weight in water vapor. Each bead is 3 – 5mm in size. Activated alumina which has excellent porosity creating tortuous paths and extended surface area can be used in both heated and pressure swing dryers. It has stable physical and chemical characteristics, even in high temperature and corrosive environments. Activated alumina has a wide variety of applications, including compressed air and gas drying. In compressed air and gas drying applications, activated alumina can achieve dew points -100°F/-73℃, depending on the dryer. It is suitable for deep drying under pressure greater than 5kg/cm2. How to Use: Place activated alumina into watertight dryer or container and then place dryer or container into the compress air or gas system. Desiccant Activated Alumina ( Aluminum Oxide) Desiccant is perfect for drying air and most other gases with relatively high humidity. How to Regenerate: 1. Use the dry gas under lower pressure or higher temperature to pass the activated alumina. 2. Use wet gas which is heated or decompressed to pass the activated alumina. The reusable activated alumina beads desiccant dehumidifier can be reactivated by placing into the oven for 8 hours at 200°C-250°C (do not over 250°C).  Activated alumina is a chemical adsorbent suitable for many industrial fields. The particle size is 3-5mm. It has porosity, uniform particle size, and a smooth surface. As an adsorbent, activated alumina is mainly used in various fields, such as industrial gas drying, liquid drying, and water purification.
