Our innovative desiccant dryers give customers efficient protection against the presence of any humidity in the air, which leads to pipe corrosion and decreased efficiency of equipment and tools. 

All materials can adsorb and desorb water, only the degree of adsorption is different per material. Desiccant used in adsorption dryers is specifically designed to adsorb moisture. Desiccants can release the water particles by adding some form of energy to them. This is called regeneration. 


Pneumatech adsorption dryers consist of two towers, 
both filled with desiccant, which alternatively operate in adsorption or regeneration cycle via a controlled switching mechanism. Once the desiccant is saturated in one vessel the process is reversed, and the second vessel starts adsorbing.

Adsorption dryers are used when PDPs (pressure dew points) from -10°C/14°F down to -70°C/-94°F are to be achieved. They make use of a material which has a high affinity to attract moisture, so called hygroscopic material or desiccant. The adsorption of moisture causes the desiccant to be gradually saturated with water.

Therefore, the desiccant needs to be regenerated regularly to regain its drying capacity. Adsorption dryers are typically built with two drying vessels (“towers”) for that purpose: the first tower will dry the incoming compressed air while the second one is being regenerated. To ensure continuity, each vessel switches tasks when the other one is completely regenerated. For critical applications and applications below 5°C/ 41°F ambient temperature, an adsorption dryer is recommended
