Compressed air dryers – DP Series

Compressed air is normally fully saturated with water vapour. Air dryers are used to remove water vapour from compressed air. Heatless desiccant air dryers are the most apt solution for drying air suitable for Compressed air, which are used in precision machines that need a Pressure dewpoint in the range between -20°C to -70°C.

How It works

Drying Cycle: Moist air from the compressor is sent through the coalescing filter. Here, water & oil coalesce and purge through the auto drain valve. The relatively clean air with water vapour passing through the aluminium drying tower filled with desiccant gets completely dried (up to -40°C ADP) and then passes through a built in after filter (1 micron). The desiccant fines from the towers are completely removed and clean dry air is let out through the outlet port for use.

Regeneration Cycle: During the regeneration cycle, the sudden depressurisation brings out water molecule strapped in the Desiccant pores to the surface of the beads. A small portion of dry compressed air from the drying tower then passes over the desiccant through the regeneration orifice built in the Top Block. This results in complete regeneration of the Desiccant.
