Design; Casing; Rotor; Filter - Trotec TTR 160 Mode D'emploi

process airflow is dehumidified in the rotor which turns
slowly (= adsorption), while the smaller regeneration
airflow is heated and thus expels the water adsorbed
from the silica gel again (= desorption).

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 chan-
nels running in axial direction and having both a large
surface and a direct connection to the internal pore
structure of the silica gel. This allows a good transition
of water vapour and it also makes for the extraordinari-
ly 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.
EN
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 be-
ing 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.
