Regenerative Desiccant Air Dryer: Everything You Need to Know

Industrial usage requires a constant supply of dry air, and it’s nearly hard to get it from the atmosphere. Moisture-sensitive gear might be damaged if compressed air is not properly dehumidified before it is used in industrial processes.

What exactly is a Desiccant Air Dryer, and how does it work?
High-quality desiccant material is used in the manufacture of desiccant air dryers, which are ideal for applications requiring exceptionally low dew points. As a result, regenerative desiccant air dryers are often constructed as a pair of towers, with one tower drying the compressed air while the other tower is regenerating. If you monitor the dew point at the desiccant dryer’s outlet, you can regulate the regeneration process more effectively by only regenerating when necessary.

How Does Desiccant Work?
Adsorbent substance desiccants have extremely high compatibility with water. The hygroscopic qualities of this unique substance allow it to sustain a dry atmosphere by attracting and retaining water molecules.

These dryers are utilized in compressed air systems that require dew points lower than those that refrigerated dryers can achieve. Industrial desiccant dryers come in three varieties: heatless, heated, and blower purge.

Heatless Regenerative Air Dryers
It is recommended that these dryers be used with lower airflow rates, higher intake temperatures, and extremely low dew points. The media bed is regenerated using compressed air that has been expanded, also known as purge air. This procedure uses 15 to 20 percent of the dryer’s nominal capacity to regenerate.

Heated purge regenerated dryers
With the help of an electric air heater, these dryers warm up the expanded purge air to a comfortable temperature. They utilize about a quarter of the energy of heatless dryers while only requiring about a tenth of the purge flow.

Blower regenerated dryers
To rehydrate the desiccant, a fan blows outside air over an electric heater. This moistens the desiccant. Energy consumption is reduced by 40% when using this dryer type since compressed air isn’t utilized to replenish the desiccant material.

For many plants, only regenerative desiccant air dryers can fulfill their needs. It’s a sad fact that too many people base their choice of the regenerative dryer only on the price tag at the time of purchase. This choice does not take into account the cost of operating the dryer. Including the cost of energy in a buying decision can have a significant impact.

Conclusion
To dry compressed air, desiccant dryers employ a medium of desiccant. Desiccant media adsorbs moisture from the air as it travels through the desiccant medium. After a limited amount of moisture absorption, the desiccant medium must be dried out or regenerated. When this is done, the desiccant medium in the tower is depressurized and the water that has collected is pushed out using purge air, heat, or a good mix of both. There are two towers in a desiccant dryer, with one bed of desiccant in each tower. During the regeneration process, one bed might be used to dry compressed air.
