3. Construction
Hereunder the separate components found in the basic construction are introduced.
Detailed information of the components is further specified in the technical appendix.
Housing
The housing of the air dehumidifier is of stainless steel, as well as the necessary means of production
and components (except the control device with display and sensor).
On the outside it consists of the casing and on the inside it consists of the Module Filter side, the
Module Operation side and the Rotor cassette. The inside is only accessible via the panels at the
backside because of the high sealed up requirements. The housing is meant for putting up inside. For
putting up outside weather protection is required.
The display is provided for the front sheet installation. It is connected through a 9-pole- Sub-D-
connection cable and can be mounted at an appropiate place.
The instrument is connected with the 7-pin connection cable on the control device U-7100. The control
device can be mounted at a suitable location/place.
Rotor (Drying wheel)
The rotor has been constructed with layers of flat and corrugated fibre membrane built from chemically
bound silicagel. In this way a multiple of axially tapered air channels with large surface and direct
connection with the inner pore structure of the silicagel. This makes a good transition of the vapour
possible and offers the extremely high adsorption capacity of the silicagel rotor.
The special construction of the rotor material brings about, that the silicagel is not interfered by
saturated air, f.i.. because of a failure of the heater or the regeneration air or with a stagnation of the
rotor.Through this the air dehumidifier can also be used with saturated air.
Through the fixed connection of the silicagel with the carrying material no sorption means is spread
into the flow of air.
The rotor has a high mechanical security and is not flammable.
Rotor Drive
The rotor is driven by a synchronous motor with flanged interruption drive. The power transmission
takes place through the deployment of synchronic discs and synchronic belts.
Rotor Bearing
The rotor has maintenance-free synthetic slide-bearing bushes on a steenless-free axle.
Sector Sealing
The separate air guide ways are sealed to the rotor box with automatic compensating seal bindings to
each other. They have been produced as closed-cell EPDM-rubber sealing and in places with
increased thermal loading as ceramic fibre sealing.
Filter
The apparatus has been provided at the air entries with synthetic Z-Line filters to prevent dust in the
air currents.
Fans
The fans have been produced as direct current-compact fans with diagonal air supply. The number of
revolutions can be changed according to standard. For this electronic manual adjustments have been
installed behind the inspection door, with which the required air mixtures can be adjusted.
