Introduction
This specification is a technical document that certifies the DanVex AD-400 dehumidifier
parameters and characteristics.
Purpose
DanVex AD-400 (in short AD-400) is designed for efficient air dehumidification with the air
humidity up to 100%, at the temperature from –20
º С to +40 º С 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.
Design
The dehumidifier answers IP 44 protection class according to IEC.
Body
The dehumidifier body is made of stainless steel. The front part of the dehumidifier is equipped
with a detachable panel that assure access for maintenance. Air ducts are connected via
standard size round air ducts. The electric panel is located in a separate section in the humidifier
upper part, the control panel is located on the dehumidifier front part.
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 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 the top
panel. Switches and indicators are located in the front part of the electric panel.
Reactivation air heater
The reactivation air heater is of PTC (Positive Temperature Control) type, its overheating is
impossible
.
Control panel
Different operation modes can be selected using the switches located in the front panel:
0/OFF
– The dehumidifier does not operate.
1/ON – The dehumidifier is in operation mode.
MAN – The dehumidifier operates in a continuous mode.
AUTO – Automatic mode at using an external humidistat or at connecting other
external control devices.
