Description

Product overview
The KXR Series heated-purge regenerative desiccant air dryer uses a portion of dry compressed air that is heated for desiccant regeneration, reducing purge consumption compared with heatless regeneration. Twin vessels alternate between adsorption and regeneration to provide continuous dry air supply.

How it works & product features
  • Heated purge air restores the moisture‑removal capacity of the desiccant.
  • Twin‑vessel design alternates adsorption and regeneration for uninterrupted operation.
  • Lower purge-air consumption versus heatless designs.
  • Available control options for cycle timing and heater management.


Main technical specifications
  • Published models: 25 (KXR-5 to KXR-5000).
  • Rated flow range: 0.7 to 510 m³/min (25 to 18,003 CFM).
  • Heater power range: 0.9 to 170 kW.
  • Connections: 1/2" up to DN350 depending on model.
  • Weight range: 150 to 16,200 kg depending on model.
