Product overview

Product designation
The product designation and the most important unit data are found on the specification label fixed on the left side of the DA 160 – 440 desiccant dryer (see example below):

Applications
The Condair desiccant dryers are based on the sorption principle and are designed to dry air of atmospheric pressure. The desiccant dryer can be used for drying air of up to 100 % relative humidity (RH) with air temperatures from -30°C to+40°C.

The applications are numerous and widespread. Below are some examples:

•  Controlling humidity levels in production processes.
• Drying of temperature-sensitive products.
• Maintaining correct humidity in storage areas.
• Protection of equipment sensitive to corrosion.
• Controlling humidity levels in museums and archives.
• Drying after water damage and drying of buildings during construction.
• Climatic improvements in damp areas.

Method of operation
The desiccant dryer operates with two air streams. A larger air stream to be dehumidified, and a smaller air stream to exhaust the moisture out of the desiccant rotor. Both airstreams are created by one com-mon fan which pressurises a compartment of the desiccant dryer creating two separate airstreams.
The larger air volume, the process air, passes through the slowly rotating silica gel rotor. Silica gel is a hygroscopic material adsorbing water vapour direct from the air. When passing through the rotor the humidity of the air is reduced, whilst the moisture content of the rotor material increases. On exiting the rotor the dried air is introduced into the area, or the process to be dehumidified. The adsorption process works in temperatures from -30°C to +40°C.
The smaller air volume, the reactivation air, desorbs the moisture from the silica gel rotor. This reactivation air is heated by an internal heater to a temperature of approximately+120°C. As the reactivation air passes through the rotor, in an opposite direction to the dry air, it will decrease the moisture content of the rotor material. The reactivation air will leave the desiccant dryer as warm, moist air, which is then exhausted out from the building.

Product description

Casing
The casing is fabricated from 1.4301 (AISI 304) stainless steel. The top of the desiccant dryer has a top hood that can be removed for service access to electrical and mechanical components. All duct connections to the desiccant dryer are designed for connections to standard size spiral ducts except for the process air inlet.

Rotor

The desiccant dryer has a drying rotor fabricated from 82% desiccant material, 16% fibreglass and 2%adhesive sealant. The rotor has a matrix of corrugated and flat heat resistant sheets, which houses the Silica Gel desiccant agent. This matrix creates a large number of axial flutes 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 drive system
The slow rotation of the rotor is achieved by an electrical gear motor and a belt drive. The belt sits on the outer rim of the rotor and is driven by a pulley on the drive motor. A adjustable 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 top panel.
The centre hub of the rotor is equipped with ball bearings. The rotor shaft is made from stainless steel. The complete rotor part can easily be removed and lifted as one piece out from the casing.

Filters

The desiccant dryer has one common air filter for process- and reactivation air. This filter primary serves to protect the components installed in the unit.

Fan for process- and reactivation air
The fan is a direct drive radial fan with a single phase standard motor class IP 54, ISO F. The fan is accessible for service after removing the service hood of the desiccant dryer. The exact type can be found in the respective table in chapter 10.

Heater for reactivation air
The reactivation heater is of the PTC-type (Positive Temperature Control), which can not be overheated.

Electrical panel
The electrical panel is located inside the desiccant dryer and is accessible through the service hood.Switches and indications for operation are mounted at the front of the electrical panel.

Operation Options
Using the operation switch on the front side of the desiccant dryer, different running options can be selected:

• Dehumidifier not in operation.
• 1 Dehumidifier in operation mode.
• MAN Dehumidifier in continuous operation.
• AUTO Automatic operation by remote humidistat or other external on/off signal.

Installation

Installation and service access
The Condair DA 160 – 440 desiccant dryers are designed for indoor installation.
All components in the desiccant dryer are accessible from the top of the unit. For inspection and service, a space of 500 mm must be left free above the desiccant dryer to accommodate for servicing of filters, fans and rotor.
When using a mounting plate, the desiccant dryer must be put so that the rotorshaft still is horizontal and the wet air outlet is placed low.

Duct connection for permanent installation
The DA 160 – 440 desiccant dryers can be installed in the room that should to be dehumidified or in a separate room.
To obtain the best performance the outlets from the fans should be equipped with diffusors.

Wet air duct from the desiccant dryer

The wet air from the desiccant dryer should be exhausted to the outside. The duct should be as short as possible to minimize the chance of condensation of the wet air. This duct should slope down in angle of at least >2°, to stop any condensed water from flowing back into the desiccant dryer. If the wet air duct is extremely long, or must be installed sloping upwards from the desiccant dryer, it should have a drainage point (2-3 mm) drilled at its lowest position.
The exhaust opening should have a coarse wire net.
A damper should be installed in the wet air duct to enable correct setting of the reactivation air volume during commissioning.

Process- and dry air with the desiccant dryer installed in the dehumidified room
When the desiccant dryer is installed in the dehumidified room space it would normally take the process air direct from the room without any duct system, with only a protection net for the inlet required.
The dry air outlet would normally have a duct system designed for distribution of the dry air in the building.

Process- and dry air with the desiccant dryer installed outside the dehumidified room

When the desiccant dryer is installed in a separate plant room all inlet and outlet openings are usually
ducted.
The desiccant dryer draws ambient air from the place of installation. The dry air from the desiccant dryer can be connected for post treatment or ducted back to the dehumidified room.
The control of the reactivation and process air volume flow takes place via the on-site installation of dampers in the wet and dry air duct.

Duct connection for basement installation
If the desiccant dryer should be installed in the basement it is sometimes desirable to achieve a slight negative pressure in the space to prevent odours from penetrating up into the building. In these circumstances the reactivation air is taken directly from the basement and the wet air is exhausted out fromthe basement. This method of installation will create a small negative pressure. The ducts should be installed according to “Duct connections for permanent installation”.

Temporary installation
With temporary installations for water damage or building drying, flexible plastic ducts would normally beused instead of the spiral duct type. The drying method differs depending on situation and construction to be dried. The complete room could be dehumidified, or just the damaged part. For the later option plastic sheet is used to cover the damaged area, and the dry air is supplied under the sheet. For both options the wet air must be exhausted out from the building via flexible duct, or alternatively connected to the general exhaust ventilation system for the building.

Electrical installation
See chapter 11 – Electrical wiring diagrams

Commissioning

On initial start-up, the following steps should be taken in this order

1. Ensure that the external isolation switch is isolating the unit from the mains, or that the power plug is disconnected.
2. Select the OFF position on the main switch (orange) at the front of the desiccant dryer.
3. Open the service hood on the top of the desiccant dryer and ensure no foreign objects are left inside the unit or in the electrical compartment
4. Make sure the air filter is installed.
5. Rotate the fan impeller by hand and make sure it can move freely.
6. Ensure that the dry and wet air dampers are open, and that ducts are clean and free of blockages.
7. Ensure that the mains supply fuse is suitably rated (10A), and that the fuse is of a slow kind.
8. Connect the desiccant dryer to the main electrical supply by turning the isolation switch to ON, or alternatively connect the power plug to the socket.
9. Select the MAN position on the operation switch (black) of the desiccant dryer. Switch the main switch (orange) to the ON position for 3-4 seconds. Check that the rotor is slowly rotating, the fans are starting, and that the orange lamp in the main switch lights up. Turn OFF the desiccant dryer.
10. Mount the service hood and ensure it seals properly to the casing.
11. The desiccant dryer is now ready for operation.
12. Start the desiccant dryer and check that the unit is operating at the correct air volumes.
13.  From the factory the desiccant dryer is electrically wired in such a way that when operating in AUTO mode, the controls operate the complete unit to start or stop. By shifting one terminal connection in the electrical panel the operation mode can be altered to operate the fan continuously. The control will then only operate the heater on/off, depending on the signal from the humidistat or other external signal.

Maintenance

Important notes on maintenance
Qualification of personnel
All maintenance work must be carried out only by well qualified and trained personnel authorised by the owner. It is the owner’s responsibility to verify proper qualification of the personnel.

General note

• The instructions and details for maintenance work must be followed and upheld.
• Only the maintenance work described in this documentation may be carried out.
• Only use original Condair spare parts to replace faulty parts.

DANGER!
Danger of electric hazard!
The Condair DA desiccant dryer is mains powered. Live parts may be exposed when the unit is open. Touching live parts may cause severe injury or danger to life.
Prevention: Before carrying out any work set the Condair DA desiccant dryer out of operation (switch off the unit, disconnect it from the mains) and secure the unit against inadvertent power-up.

WARNING! Risk of injury!
Inside the Condair DA desiccant dryer there are moving parts present, which can cause serious injury to hands and fingers.
Prevention: Before carrying out any work set the Condair DA desiccant dryer out of operation (switch off the unit, disconnect it from the mains) and secure the unit against inadvertent power-up.
Keep hands or other body parts away from moving parts.

WARNING! Risk of burns!
Inside the Condair DA desiccant dryer are heating element present, which can cause burns if touched. Prevention: Before carrying out any work set the Condair DA desiccant dryer out of operation (switch off the unit, disconnect it from the mains), secure the unit against inadvertent power-up, and wait at least 15 minutes prior to opening any service panel, allowing the heater to cool down.

The maintenance intervals for the desiccant dryer depend on the surrounding environment and instal-lation site. Recommended maintenance intervals could therefore differ from one installation to another. Incorrect maintenance and service may result in reduced dehumidification capacity.

Filters
The desiccant dryer is equipped with one common filter for the process air and reactivation air. The filter is positioned at the inlet and will clean the air prior to entering the desiccant dryer.
Intervals for cleaning or replacement of the filters will be determined by the amount of dust and particles in the air at the installation site.
We recommend that the filter is checked at least once a month, at least for the first year of a new installation.

CAUTION!
Never operate the desiccant dryer without the filters, as the rotor can be damaged by dust.

Rotor
The rotor is maintenance free. However should it be necessary to clean the rotor the first choice should be careful use of compressed air. With severe contamination, the rotor can be washed with water. Cleaning with water is no routine matter; please contact your Condair representative.
Check the rotor bearing and the rotor surface once a year.

CAUTION!
Airborne chemical compounds, e.g. oily vapors or solvents can also be adsorbed by the rotor and permanently reduces its capacity.

Electrical motors
The electrical motors are equipped with ball bearings. The bearings are designed to last the life of the motor and therefore no maintenance is required.
Check the motors once a year for any abnormal sound.

Heater
The reactivation electric heater does not need maintenance, but should be checked twice a year for any dust or mechanical damage to the heating rods. Clean with a soft brush, or vacuum clean with dust. Gentle use of compressed air is another alternative.

Rotor drive belt
Check the belt tensioning at regular intervals. Adjust when needed by moving the tensioning support wheel closer to the desiccant rotor.
