Desiccant Air Dryers

Adsorption or desiccant dryers eliminate moisture from air or gas streams by directing them through a porous substance, known as a desiccant. This guarantees dry and moisture-free environments.

Adsorption / Desiccant air dryers to remove moisture from your air compressor system today!

Utilizing a desiccant, often termed a hygroscopic material, adsorption dryers extract moisture. As compressed air passes through the desiccant, it sheds moisture. Upon saturation, the hygroscopic material undergoes regeneration, expelling and draining moisture to restore desiccant functionality. 

In order to maintain constant operation of the dryer, a typical adsorption dryer is made up of two towers filled with desiccant. While one tower is drying the air, the other is being regenerated. Pneumatech not only provides traditional adsorption dryers, but also innovative new models featuring The Solides structured desiccant, which offers numerous advantages in terms of effectiveness and dependability (for more information on the benefits of solid desiccant, click here).

Adsorption dryers are utilized when achieving pressure dew points (PDPs) ranging from -10°C/14°F to -70°C/-94°F is necessary. They are also ideal for critical applications and operations in temperatures below 5°C/41°F
