Compact heatless air dryer works on the principal of absorption. regenerative air dryers use desiccant media absorbs moisture contaminate from compressed air. The desiccant media can be regenerated by purging air and remove moisture it collect and remove again and again. So the dryers of the compressed air achieved up to atmospheric -40˚c dew point. The traditional refrigeration heat less dryer does not provide sufficient air quality required for special application. WELLTECH regeneration heatless dryer contains smooth uniform achieved alumina balls size that prevents channeling of compressed air flow, which maintains low bed velocities. This maintains air contact time for efficient moisture removal and minimal pressure drops. WELLTECH have electronic control timer for pneumatically pilot valves are chosen for long life and high air flow. A pre filter. oil removing filter, after filter offering purification to 5 micron can be specified. Purge loss and pressure drop are kept at a minimum resulting in lower operating costs.

These dryers are used for instrumentation and process applications as well. Some applications are , CNC machines , CMM machines , Spray painting , Nitrogen generators , laboratory air & gas applications , powder coating, etc.


During an operating cycle inlet air directed to pre filter, here moisture and dust particles are removed then air enters to oil removing filter here we remove flooded oil. As wet air flows through the desiccant tower bed the twin tower design of our dryers allows simultaneous compressed air drying and desiccant regenerated without interruption to the compressed air flow. At the end of the drying cycle the regenerated tower is re-pressurized and tower operation is reversed automatically. After tower change over wet inlet air is directed to the regenerated tower and the previously used desiccant is regenerated by the same process. A completed cycle of drying and regeneration is 10 minutes or 6 minutes timing is precisely controlled by WELLTECH electronic timer.
