Working Function
Adsorption dryers primarily utilize the principle of physical adsorption, where the physical adsorption force is the van der Waals force (VDW). The van der Waals forces between molecules cause the adsorbate (water vapor) to penetrate into the adsorbent, resulting in a lower dew point temperature and drier gas. Based on the temperature and pressure conditions of the adsorption and regeneration processes, heatless regenerative dryers employ pressure swing adsorption (PSA) technology. Pressure swing adsorption involves adsorption (of water vapor) at high adsorption pressure, and then utilizing the heat of adsorption stored in the adsorbent during the adsorption process for desorption at a lower pressure.
