Activated Alumina Balls for Heatless Air Dryers

  • Monday , Dec 02, 2019

Activated Alumina is an aluminum oxide that is highly porous and thereby has huge surface area. Being resistant to thermal shock and abrasion it will not Shrink, Swell, Soften neither they disintegrate when immersed in water.

Activated Alumina Balls having Surface Area in the range 345-415 m2/g is mainly used as an Adsorbent for warm gases including air. Primarily it is used for Air Drying & low-temperature applications for getting better dew points. Activated Alumina Balls are mainly used in Heatless Air Dryer for adsorbing moisture from Air.

                                                                      Air Dryer Desiccant

Heatless Air Dryer is the simplest form of Gas or Air Dryer. It can achieve a dew point of -40°c for the compressed air systems as well as the other application of gas and Air dryers. Once it is passed through Pre-Filter, the wet incoming compressed air passes through the assembly of Slide piston. Next, this air is directed towards the first chamber where it travels through the desiccant bed which contains Activated Alumina Balls. Our Activated Alumina Balls having High Adsorption Capacity would easily absorb moisture that is present in Air. Now this Air is passed through some check valves and then to after-filter and directly provided for end-use. Now Activated Alumina Balls used a desiccant present in the Second Chamber that had been wetted in the previous cycle regenerates at the simultaneously as the compressed air dries in the first chamber.

Thus using Activated Alumina Balls for Air Drying would give Dew Point of -40°c and would absorb moisture present in the air thereby providing dry air to be used in the end application.
