Refrigerated air dryers account for a majority of the compressed air dryer applications. Quality and efficiency is important for compressed air treatment, using refrigerated air dryers easily provides continuous dry air. The refrigeration system cools the incoming compressed air, allowing the water to condensate and drain. There are two different types of refrigerated air dryers, cycling units and non-cycling units.

Desiccant air dryers purify compressed air by adsorbing moisture. The process of drying occurs when the compressed air sent through a vessel contains a pair of drying agent towers. The moisture is transported through adsorption and the drying process switches to the other tower. Allowing the system to blow the material dry.

The desiccant dryer can also be referred to as adsorption dryers or regenerative desiccant dryers. There are different types of desiccant air dryers, including heatless, externally heated, blower purge and dual or single tower setup.

Gardner Denver's desiccant air dryers maintain controlled humidity environments. Industries where the drying process is crucial, rely on the desiccant dryers to maintain the quality of products.

Desiccant dryer systems are important in many industrial applications. Industries that require the drying process to maintain the integrity of options and quality of the product.

Protection against the presence of any humidity in the air.

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.

For increased efficiency and an extended life span of your compressed air equipment.

Why do I need a membrane dryer and how does it work?

Untreated compressed air always contains water. As water is incompressible, the amount of moisture per volume increases when air is compressed. The maximum amount of moisture per volume of air (the so-called holding capacity of moisture in the air) is however limited for a certain temperature. Condensation forms when air is compressed.

Refrigeration technology is by far the most used dryer technology and is applied to more than 95% of industrial applications.

Refrigerated air dryers use the same cooling principle as typical home air conditioning units. Pneumatech offers long-lasting corrosion protection to the condenser and refrigerant piping without affecting heat transfer and pressure drop. The heat conductive pigmentation in the coating creates a very high chemical resistance at a low layer thickness making it the best available option to prevent refrigeration dryer failure and unnecessary energy consumption.
