The food and beverage industry, pharmaceutical companies, hospitals, and galvanic treatment processes have one critical common requirement – very clean and dry compressed air. Pneumatech adsorption air dryers are the energy efficient solution to achieve this high-quality air. 

Adsorption drying is a chemical process. It all starts with compressed air, which is saturated with moisture after it leaves the compressor. This can compromise your entire air system, your pneumatic tools as well as your final products. To avoid corrosion and contamination, compressed air must be dried. This is where adsorption air dryers come in. 

As untreated air passes through these dryers, the moisture content in the air attaches itself to hygroscopic material. This desiccant can be silica gel, molecular sieves, or even activated alumina. It can also be solid or liquid. 

As the desiccant adsorbs the moisture from the air, it gets saturated. That is why Pneumatech’s adsorption air dryers feature two drying vessels. While one is drying air, the other is regenerating its saturated desiccant. The towers are engineered to switch tasks when one is completely regenerated.
