Heat less 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 dryness of the compressed air achieved up to atmospheric -40'c dew point. The traditional refrigeration type air dryer does not provide sufficient air quality required for special applications. Guru regeneration heat less dryer contains smooth uniform achieved alumina balls size t\at prevents channeling of compressed air flow, which maintains low bed velocities. This maintains air contact time for efficient moisture removal and minimal pressure drops. Guru 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.
