Increased Moisture Removal
Desiccant air dryers are designed to remove moisture from compressed air. By removing the moisture, these dryers help prevent the formation of condensate, which can cause corrosion and damage to equipment.
What Are Desiccant Air Dryers?
Desiccant air dryers are a type of compressed air dryer that operate on a simple principle: moisture removal from the compressed air stream. These heavy-duty, industrial-grade devices ensure tools like paint sprays, plasma cutters, and pneumatic devices run efficiently without risk of moisture damage.
Considered an integral part of any air compressor setup, desiccant air dryers are widely sold by various small business brands. The system often comes as part of a stage air drying system, including a coalescing filter, a moisture water separator, and a mid-flow line desiccant air dryer. These intricate systems safeguard your products from potential harm caused by moisture, particulate, and water contaminations, enhancing their longevity and performance.
Desiccant air dryers utilize a twin tower setup to dry the compressed air. Each tower is filled with a desiccant material, usually silica gel or activated alumina. The drying process typically involves two stages: drying and regeneration.
Drying
During the drying stage, the wet compressed air enters one dryer tower through an inlet valve. As the air passes through the tower, the desiccant material absorbs the moisture from the air, leaving it dry. The dry air then exits the other side of the tower through an outlet valve and is ready for use in various applications.
Meanwhile, the moisture-laden desiccant in the first tower becomes saturated and needs regeneration. The regeneration stage is carried out in the second tower while the first tower dries the incoming compressed air.
Regeneration
To regenerate the desiccant material, a small portion of dry air is diverted from the outlet valve and sent through the second tower. This dry air flows through the saturated desiccant, absorbing the moisture from it.
After regeneration, the moisture-laden air exits the second tower through an exhaust valve, preventing the moist air from contaminating the dry air supply. The exhausted air is known as purge air and is released into the atmosphere.
The drying and regeneration stages alternate between the two towers, ensuring a continuous supply of dry air. This cycle is automatically controlled by a controller in the desiccant air dryer, which monitors the air quality and switches towers when necessary.
