System operation strategy
This section describes the operation strategy of the adsorption dryer.
The following diagram illustrates the method of operation of the adsorption dryer:
Fig. 4
The room air (= process air) taken in is fed through the turning adsorption rotor. The adsorp-
tion rotor is a high-performance rotor. By its metal silicate coating it has been optimised for
maximum water adsorption under different intake conditions. The slow rotation of the rotor
results in an automatic, continuous drying/regeneration process.
Due to its honeycomb structure the rotor features a very large surface. The mechanical
strength of the surface is extremely high. The rotor is non-combustible, maintenance-free and
washable.
The moisture taken up by the rotor is fed back out of the rotor by a heated air current (=
regeneration air) flowing in the opposite direction.
The regeneration air is heated by a dynamic, safe and self-regulating PTC heating element.
The moist air current is discharged at the regeneration outlet (see Fig. 1 and Fig. 2) and must
be removed from the room via a hose or air duct (see page 12).
