Desiccant dryers are devices used to dry and purify compressed air and are widely used in industries that require high-quality dry air. Depending on the working principle, type of adsorbent, and application scenarios, there are several types of dryers, including blower purge dryers, heated purge dryers, and heatless desiccant air dryers.
Among them, heatless desiccant air dryers operate based on the pressure swing adsorption principle and do not require external heating. They regenerate the adsorbent using a portion of the dried air. This type of dryer has a simple structure but relatively higher purge air consumption and is suitable for small to medium-sized compressed air systems.
To achieve a dew point below -30°C with a heatless desiccant air dryer, a specialized adsorbent is required—one that can effectively regenerate under low temperature and pressure, while maintaining strong water adsorption performance under high pressure. JOOZEO‘s activated alumina JZ-K3 is a specially developed adsorbent for heatless desiccant air dryers.
Under the same testing conditions, it delivers 16% higher dynamic adsorption capacity than standard products. Thanks to its easy desorption and regeneration properties, it is ideal for achieving effective drying performance in low-temperature regeneration conditions.
