Activated Alumina

Devson is the one of the largest manufacturer of Activated alumina (DEV-101™) in India with capacity of 3600 MT per year. Devson is having most modern manufacturing facility and advance technology of spin flash calcinations of alumina which calcine each and every molecule of alumina resulting the high quality properties such as Adsorption, Surface area, Pore Volume and Mechanical strength with low attrition loss. Devson Activated Alumina is designed to give a dew point of at least -40° C in most conditions.
