An example of a compressed air drier that uses a regenerative desiccant method to remove moisture from the compressed air is a heatless desiccant air dryer. The heatless desiccant dryer does not require external heat sources for regeneration, in contrast to heated air dryers. Instead, it regenerates the desiccant substance typically silica gel or activated alumina that absorbs the moisture from the compressed air using the dry, compressed air itself.
1. Heatless desiccant dryers frequently have two desiccant-filled towers, one of which is in the drying stage while the other regenerates.
2. Purge Valves: The dryer has purge valves to let out moist air while it regenerates.
3. PLC Control: For accurate and effective operation, advanced versions may come with a programmable logic controller (PLC).
4. High-quality desiccant materials provide efficient moisture removal.
5. Air dryer systems may have filters at the inlet and outlet to shield the desiccant beds from impurities.
1. Heatless desiccant air dryers efficiently remove moisture from the air, reducing water-related problems in pneumatic equipment and systems.
2. Continuous Operation: A steady supply of dry air is guaranteed because to the twin-tower design's ability to dry and regenerate continuously.
3. Energy-efficient: The heatless operation uses less energy, which reduces costs.
4. Low Dew Points: Because these dryers can reach low dew points, they are appropriate for demanding applications requiring high levels of air quality.
5. Heatless desiccant air dryers are dependable in a variety of industrial situations and require less maintenance due to their straightforward design and lack of external heat sources.
For applications requiring high-quality compressed air with low moisture content, such as those in the pharmaceutical, electronics manufacturing, food processing, and other sectors, heatless desiccant air dryers are frequently utilised.
