 Trident Desiccant Compressed Air Dryers

All Trident Dryspell Plus Dryers are equipped with Energy Saving variable purge control as standard equipment.

Imagine being able to reduce purge loss to only 6% - dependent on desired dew point. Variable purge loss + variable dew point.

Drying Cycle – Moist air from the compressor is sent through the inlet port of the required coalescing filter where water & oil coalesce and are purged through the electronic drain valve. The clean air with water vapor passes through the control valve into the desiccant filled drying tower where the air is completely dried. The air then exits through a built in strainer and a required external particulate filter giving the customer incredibly clean and dry air (-40° C PDP).

Regeneration Cycle – The Regeneration Cycle occurs every 2 minutes for a period of 90 seconds. During this cycle, the control valve at the bottom of the tower opens and depressurizes. This sudden depressurization brings out water molecules trapped in the desiccant pores to the surface of the beads. A small portion (up to 15%) 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.
