ADSORPTION DRYER ADX-F-PDP with dew-point control -
maximum drying efficiency,
minimum costs

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.

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.
