HF, HCl, SO₂ ADSORPTION
Adsorbs not only water but also acidic gases
Strong performance for tough conditions
When aluminum hydroxide powder is heated so strongly that all moisture is driven off, activated aluminum oxide is produced, resulting in a very special drying agent. Pressed into granules, small spheres are formed that develop countless tiny pores on their surface, where water molecules can attach.
Its unique feature: Due to the heating process, they are extremely robust against high process temperatures and mechanical stresses. Nevertheless, they still maintain good adsorption performance and can absorb up to 25% of their own weight in water at moderate humidity.
Its robustness makes the drying agent ideal for use in compressed air dryers, in gas processing, or in PSA plants for oxygen processing.

FAQ - your questions, answered.
Yes, activated alumina physically adsorbs molecules. Heating the granules to 200–220 °C for 2–4 hours reverses this process and regenerates the material.
