Introduction
This specification is a technical document that certifies the DanVex AD-10000 dehumidifier
parameters and characteristics.
Purpose
DanVex AD-10000 (in short AD-10000) is designed for efficient air dehumidification with the air
humidity up to 100%, at the temperature from –20ºС to +40ºС with minimum energy
consumption. It can be used either as an independent unit for installation inside and outside of
premises where air humidity control is required or along with an air treatment system.
Operation principal
The main dehumidifier part is a rotor having a cellular structure made from fibrous ceramic
material and SelicaGel. The rotor is divided into two zones by a sealing device: one for
dehumidification, another for regeneration.
Thus, the dehumidifier works with two air flows. The volume of the dehumidified air is bigger. The
air flow of a smaller volume is used for moisture removal from the dehumidifier rotor. The rotor is
subject to the action of different oppositely directed air flows by sectors. The air flow to be
dehumidified (PROCESS AIR) passes through the biggest sector. The moisture from the air is
trapped (adsorbed) by the rotor material. The air leaves the rotor in dehumidified condition (DRY
AIR) and is directed to a certain part of the building or a technological process where
dehumidified air or a certain air humidity levels are required. Since the rotor rotates slowly the
incoming air always contacts with the rotor active part, thus a continuous dehumidification
process is assured.
The air flow used for the rotor regeneration is called regeneration air (REGENERATION AIR). It is
о
heated up to 140 С and when passing through a small sector it removes the moisture trapped by
the rotor material. The moisture is removed from the rotor in the form of humid air (MOIST AIR)
which is discharged outside the dehumidified loop

· The rotor is reactivated by another air flow preheated to 140 C. The moisture is removed from the room
in the form of moist air.

Design
The dehumidifier answers IP 44 protection class according to IEC.
Body
The dehumidifier body is made of stainless zinc-plated steel. It is thermally insulated which
allows the dehumidifier to be used in low-temperature premises and prevents condensate
formation inside the dehumidifier.
The body has a frame structure which allows easy moving of the dehumidifier during
transportation and installation.
The dehumidifier is equipped with detachable panels and doors that assure access for
maintenance and repair.
The rotor drive belt tension mechanism and a sealing system assures the dehumidification
reliable and efficient operation.
Rotor
The dehumidifier is equipped with a drying rotor manufactured in accordance with unique
technologies covered by a patent in force. The rotor represents a matrix consisting of numerous
air channels. It is made of composite material with introduced active SelicaGel and assures a
very large contact area with air flow for moisture adsorption in the small volume of the rotor. This
material is highly efficient for water molecules attraction and retention, it is noncombustible and
explosion-proof, with a long service life. The rotor manufacturing technology assures production
of a product capable of saturated air processing without risk of destruction, it means that the
rotor can be used along with a precooler. Besides, the rotor will not be damaged even if the fan or
the reactivation air heater fail to function.
Filters
The dehumidifier is equipped with two filters. One filter is located at the dehumidified air inlet, the
another one is installed at the reactivation air inlet.
Air flow fans: for dehumidified air flow and for reactivation air flow
The fans are of a radial type, single phase, IP 54 class, ISO F. The fans maintenance can be
performed after the service panels are removed.
Electric panel
Electrical components are located inside the dehumidifier and can be reached through
detachable or opening panels. Switches and indicators are located in the front part of the
dehumidifier.
Reactivation air heater
The reactivation air heater consists of a heating element.
Control panel
DanVex AD- 00 100 dehumidifier is equipped with an automatic control system. All commands
are input using the buttons located on the control panel with a LCD-display.

Installation
Installation and the covered area
AD-10000 dehumidifier is designed for indoor installation. It should be positioned upright on an
even surface. It is recommended to fix the dehumidifier. It is required to leave some free space
(1500 mm) in front and above the dehumidifier for filters, fans and rotor maintenance and
inspection.
Channel connections for permanent installation
The dehumidifier can be installed directly in the room to be dehumidified or in a separate
ventilation chamber. In case of special versions it can be places outdoors as well. To assure
better parameters and efficiency the air outlets should be equipped with diffusers.
Moist air duct
Moist air should be discharged outside the dehumidified loop (to outdoors). The air duct
should be as short as possible to minimize the possibility of condensation of the moisture
from the moist air. The duct should be slightly inclined downwards to prevent the condensate
entering the equipment. In case it is required to install the moist air duct upright it should be
insulated and drain holes should be drilled in the lowest part of the elbow bend (2-4 mm).
Regeneration air duct
The regeneration air duct should be as short as possible. A metal net is installed at the duct input
to prevent foreign matters entering the dehumidifier. There is no need to insulate the duct. The
duct inclination angle is optional.
Dehumidified and dry air ducts at the dehumidifier installation inside the dehumidified
loop
As a rule in case the dehumidifier is installed in the dehumidified loop air ducts for the air intake
are not required. A dry air duct is connected with the air-ducting system for dry air distribution
inside the premises.
Dehumidified and dry air ducts at the dehumidifier installation outside the dehumidified
loop
In case the dehumidifier is installed outside the dehumidified loop either a recirculation or an
open circuit is used. If a recirculation circuit is used the air to be dehumidified is supplied from the
loop via an air duct and the dehumidified dry air is supplied to the dehumidified room the same
way. If an open dehumidification circuit is used only dry air is supplied to the room.
