slowly (= adsorption), while the smaller regeneration
airflow is heated and thus expels the water adsorbed
from the silica gel again (= desorption) .
03. DESIGN
Casing
The air dehumidifier has a casing made of stainless
steel which contains all necessary equipment .
Rotor
The air dehumidifier is equipped with a patented silica
gel rotor .
This rotor is made of flat and corrugated non-woven
layers consisting of chemically bonded silica gel and
metal silicate . This creates a large number of air
channels running in axial direction and having both
a large surface and a direct connection to the inter-
nal pore structure of the silica gel . This allows a good
transition of water vapour and it also makes for the
extraordinarily high adsorption capacity of the silica
gel rotor .
The dehumidifier is a continuously working device with integrated heat recovery, and it can reach very low
dew points . By turning, the rotor carries the thermal energy from the hot regeneration zone to the rinsing zone,
the rotor cools down while heating the entering regeneration air . As a result, process air is less hot and
the dew point is lower .

The particular manufacturing process of the rotor ma-
terial makes certain that the silica gel is not destroyed
by saturated air . This makes it possible to operate the
air dehumidifier with pre-cooling . No damage will be
caused even when the heating or the regeneration
airflow fails .
The permanent link between the silica gel and the
base material prevents the sorption material from
being carried away by the airflow .
No super-saturation will occur even when the rotor is
not operating, thus not requiring any particular safety
measures .
The rotor has a high mechanical resistance and it is
non-flammable . The rotor is driven by an electric mo-
tor with a toothed belt transmission .
Filter
The filter mat is made of standard non-woven fabric .
Fan
The fan is driven directly by an electric motor .
