Product information
The GRGDR series regenerative dryers from GRAF S.p.A. consist of two columns filled with molecular sieves and are equipped with an automatic closed-circuit regeneration system, thus preventing any gas release into the atmosphere.
Fully automatic, they are able to change state without operator intervention. The material used for absorption is of the highest quality and is capable of achieving a dew point level of up to -80 °C.
