9Product overview
4.2 Applications
The Condair desiccant dryers are based on the sorption principle (see description of the operating
principle in the installation and operation manual for the Condair DA 500-4000 desiccant dryer), which
removes unwanted humidity from the air at normal atmospheric pressure.
The desiccant dryer can be used at air temperatures from 0 °C to 40 °C and humidity values of up to
100 %RH.
Typical elds of application for desiccant drying are:
– Control of humidity in production processes.
– Drying of temperature-sensitive products.
– Maintaining the correct humidity in storage rooms.
– Protection of corrosion-sensitive equipment.
– Humidity control in museums and archives.
– Drying after water damage and drying buildings during construction.
– Climatic improvements in humid rooms.
Compared to the normal design, DA 500-4000 Compact desiccant dryers are characterized by a single-
walled housing without any insulation material. This particular construction offers an excellent solution
for applications where there are not large temperature differences, e.g. with heavily pre-cooled process
air and where noise emissions do not have top priority. In addition, this construction leads to a more
compact device with a signicantly lower weight.
4.3 Operation principle
The operation principle of the DA Compact desiccant dryer is identical to that of the Condair DA 500-4000
standard devices. Please note the information in section 4.3 of the installation and operation manual for
the Condair DA 500-4000 desiccant dryer.

10 Product overview
4.4 Product description
The Condair DA 500-4000 Compact desiccant dryers with applied ducting meet the requirements of IEC
protective class IP23. The electrical panel meets the requirements of IEC protective class IP44.
4.4.1 Casing
The housing is powder coated in RAL7035 and is made from 1 mm thick Aluzinc®. The construction with
sealing material on the panel and internal construction achieves high tightness.
The service-friendly design allows easy access to internal components via a removable front panel. All
air duct connections are prepared for the connection of standard spiral ducts.
4.4.2 Rotor
The desiccant dryer has a drying rotor made of 82% desiccant silica gel, 16% breglass and 2% adhe-
sive sealant. The rotor has a matrix of corrugated and at heat resistant sheets, which houses the Silica
Gel desiccant agent. This matrix creates a large number of axial utes through the rotor, which together
builds up an immense surface area for moisture adsorption in a small volume. The rotor is manufactured
and processed to be able to withstand moisture-saturated air without being damaged. Furthermore, the
rotor will not be damaged even if the fan or the heater for reactivation should fail during operation. The
desiccant rotor is tested according to ASTM E84-18b, and the results are Flame Spread Index (FSI) 0
and Smoke Developed Index (SDI) 0.
Rotor sealings
The rotor has two peripheral seals (PTFE/Silicone) on the rotor casing and four radial seals (PTFE)
Rotor drive system
An electrical gear motor and a belt drive achieve the slow rotation of the rotor. The belt sits on the outer
rim of the rotor and is driven by a pulley on the drive motor. A belt tension device keeps the belt in place
and maintains tension to prevent belt slip. Correct operation of the drive system, and direction of rotation
can be checked by opening the front panel.
The centre hub of the rotor is equipped with ball bearings. The rotor shaft is made from stainless steel.
4.4.3 Airlters
Two separate air lters class ISO coarse ≥65% are installed on the inlet of each air ow. These lters
protect primarily the internal components from dust.
4.4.4 Fans for process- and reactivation air
The device is equipped with two directly driven centrifugal fans, IP54 and ISO F, installed in the device.
The exact type can be found in the respective wiring diagram.

11Product overview
4.4.5 Heater for reactivation air
For the units with electrical reactivation air heating, the reactivation heater is of the PTC-type (Posi-
tive Temperature Coefcient). These special PTC heating elements offer the usual protection against
overheating.
From the DA 1400 onwards, the electrical reactivation heating has a 2-stage control as standard. A
modulated control of the reactivation heater is available as an option.
4.4.6 Electrical cabinet
The electrical cabinet is located in a separate compartment on the service side of the desiccant dryer.
The main switch and PLC display are located on the front on the right-hand side.
4.4.7 Operation Options
The operation of the desiccant dryer with a description of the built-in PLC can be found in the separate
PLC controller manual.
