Heatless

Heatless Dryer

Exal heatless dryers work on the principle of adsorption. Wet Compressed air is passed through a desiccant. The moisture from the compressed air gets adsorbed on-to the desiccant. This results in drying of the air. Subsequent stages of regeneration take place in order to make the desiccant re-usable.


Heatless Type (10-2000 cfm)

Exal made heatless dryers have been optimized to suit industry needs. The heatless dryer consists of 2 towers which, alternately cycle on drying and regeneration. Each tower is filled with a bed of adsorbent desiccant. The tower on drying cycle adsorbs the moisture from the incoming wet air. The tower on regeneration uses a small portion of the dried air passing through the desiccant to remove the adsorbed moisture. This air is later vented to the atmosphere. The cycle is maintained using a control panel.

Features of Heatless Type (10-2000 cfm)

  • Can be designed for high pressures
    • Exal can design heatless dryers upto 100 barg heatless dryers provide constant -40°C Atmospheric dew point or better.
 
  • Can be designed for lower dew points
    • Exal can design heatless dryers upto -70°C Atmospheric dew point.
    • All dryers have minimum pressure drop
 
  • Pre-filter provided at the inlet
    • Protects the desiccant from dirt and water contamination.
 
  • After-filter provided at the outlet
    • Prevent carry forward of dust.
 
  • Fully Automatic and Continuous
 
  • Simple, compact and reliable construction
 
  • Easy installation
 
  • Activated Carbon / Borosilicate Glass Fibre Filter
    • Borosilicate Glass Fibre Filter are used for oil removal
    • Lubricated compressors pass oil to the dryer. (oil reduces life of desiccant)
 
  • Heavy duty control valves for long life.
