How Do Desiccant Air Dryers Work? Desiccant air dryers employ a twin-tower design, consisting of two tanks or towers filled with desiccant material. One tower is actively drying the compressed air, while the other is being regenerated. The drying process typically involves two main steps: adsorption and regeneration.

Refrigerating air dryers work by cooling the air to low temperatures and condensing the bulk of the water vapour. In other words: it uses temperature differences to remove the water particles. Refrigerated air dryers or refrigerant dryers cool down the air to approximately 3°C or 35°F. At this temperature, known as the dew point, the moisture …

Without proper filtration, desiccant air dryers will not work. Desiccant dryers are designed to adsorb vapor from compressed air they are not designed for liquid. When liquid, especially oil, is allowed to enter the desiccant chamber, it coats the desiccant material preventing any further adsorption. Oil coated desiccant can not be regenerated,

Adsorption dryers are used when the compressed air application requires a pressure dew point below 0°. The regenerative desiccant dryers consist of two pressure vessels. Both vessels are filled with desiccant. One vessel is removing moisture from the compressed air. Wet air passes directly through the desiccant bed which adsorbs the moisture.

A desiccant in an air dryer is a specialized material, typically silica gel or activated alumina, which is held in two separate chambers. As the compressed air enters one of the chambers, the desiccant beads adsorb moisture molecules from the incoming air, effectively trapping them on the surface of the desiccant material.

desiccant dryers work? Desiccant dryers consist of two towers filled with desiccant such as activated alumina, molecular sieves or silica gel. Wet compressed air passes directly through the substance, which adsorbs the moisture. The desiccant has a finite adsorption capacity before it must be dried out. Hence the twin tower design.

Normally, the desiccant is contained in two separate towers. Compressed air to be dried flows through one tower while the desiccant in the other is being regenerated. This is accomplished by reducing the pressure in the tower and passing previously dried purge air through the desiccant bed. The regeneration air may also be heated, either within ...

The lower the air pressure, the higher the velocity of the air moving through the air dryer. This results in less contact time with either the heat exchanger (in a refrigerated air dryer) or the desiccant beads (in a desiccant dryer). The lowered contact time results in less efficient drying of the compressed air, thus reducing drying capacity.
