Adsorption dryers ADX-F-PDP with dew-point control

The ADX-F-PDP series, equipped with the most advanced control systems and comprising a modern LCD display controller, a measuring chamber for constant flow and a precise dew-point sensor, provides the highest quality compressed-air drying at the lowest possible cost.


  • LCD display controller
  • Precise dew-point sensor
  • Measuring chamber
  • Installed pre- and after-filters

The air demand and the load situation for an adsorption dryer fluctuate constantly on a daily basis.

The Comprag dew-point-dependent control system significantly reduces energy costs while ensuring a constant and reliable dew point. Using the specially developed controller in combination with the accurate and reliable dew-point sensor, the DPD control system keeps the regeneration time constant, while the adsorption time is adjusted strictly proportionally to the load situation. As a result, only the actually required quantity of purge air is used. An investment in the PDP control system has a very short return on investment — as early as within six months.
