Our organization is widely trusted in offering Activated Alumina Balls to our clients. Adchems provides Alumina Balls in 2 sizes: 2 – 5 MM dia & 5 – 8 MM dia, manufactured by our manufacturers at the State of the Art Technology plant in Mehsana (Gujarat). The products have at least equal to & some cases, better properties than what have been specified in the Bureau of Indian Standards: BIS 9700 (Revised 1991). Specifically it has very high water adsorption capacity 7 mechanical strength & at the same time very low attrition loss. Its main application is in air drying; however, it may be used favorably for purification of drinking water (fluoride removal) & removal of acidic vapour from gases. The robust nature of this product makes it suitable for application in high pressures. Our Activated Alumina is designed to give a dew point of at least 40°C in most conditions. However, in case of rigorous adsorptive drying, under high pressure, the moisture content in the exit gas or air may go down to less than 1 ppm (i. E., a dew point of -70°C & better).
Precise pH balance
Activated Alumina has infinite shelf life, when stored in packed condition. The active service life would depend, however, on the operating conditions of the plant, actual application & the usage of the customer
Surface area by Benzene adsorption method. The values are lower when measured by BET Nitrogen method (300 – 320 m²/gm). Owing to carcinogenic threat to environment, safe method of Nitrogen Adsorption is adopted
For spheres of more than 5 MM diameter, the specific surface & water adsorption capacity values are approximately 10% lower than the above figures
