4. General description.

4.1 Background.

Modern standards concerning human comfort and the environmental requirements for manufacturing, storage & preservation of products and materials, make increasing demands on the control of moisture content in the working environment.

Where the natural or treated environment have an ambient condition holding more water vapour than the specified or desirable conditions, it is necessary to integrate equipment which can reduce humidity to the desired level.

FISAIR ROTARY DESICCANT DEHUMIDIFIER provides the solution

The FISAIR dehumidifier is simple to install, reliable in operation and will provide long lasting humidity control at a reasonable running cost.

4.2 The desiccant wheel. Operating principle with integral heat recovery

In DFRB series the face of the cylinder is divided in three zones:

!

The Process Air Zone occupies 210 degrees approximately of the circle's face. In this section the desiccant removes moisture from the process air passing through the rotating desiccant cylinder.

!

The Reactivation Air Zone occupies 90 degrees approximately of the circle's face. In this section the reactivation air passes counterflow, previously heated to a temperature enough to open the desiccant pores, removing moisture from the desiccant.

!

The Heat Recovery Zone occupies resting 60 degrees of the circle's face. In this section the reactivation air, before reaching the air heater, passes through the desiccant wheel in the

Process Air direction, cooling down the desiccant material while reactivation air is pre-heated causing the heater consumption to decrease.

The above schematic drawing shows the FISAIR series

DFRB dehumidifiers main components disposition as well as the air flow diagrams.

These models have relative low air flow and they incorporate a direct driven single ear centrifugal fan that moves the process/dry air as well as the reactivation/wet air. The air is aspired by the fan through circular connections, filtered and impelled against one face of the desiccant rotor. By means of the opportune partitions of the frontal area of the desiccant rotor, part of the impelled air suffers a direction change of 180 degrees, passes through the reactivation air heater, and then crosses counterflow the desiccant rotor which is this way reactivated for a new cycle. Dry air and wet air outlets are made also with circular standard connections.

F-2833 - 5 - Technical Data Subject to alterations

Installation, Operation and Maintenance Manual

Desiccant Rotor Type Air Dehumidifiers DFRB series

The unit electrical components are disposed into an enclosure with a folding cover located at the upper right front of the unit that can be accessed loosening the screws. The following items can be found in the front:

!

One ammeter to show the reactivation heater current.

!

One on/off switch with lighting indicator.

!

Two cable conduits for the electric mains and the hygrostat connection cables and/or remote on/off.

!

In 3-phase models, an isolating switch.

The driving motor, fan and filter are easily accessible by dismounting the upper cover of the unit, fixed by Tknob screws, that can be tighten or loosen by hand.

The air heater is located at the bottom central part of the unit. This can be accessed dismounting the front protection cover which acts also as reactivation air deflector.

4.4 The PTC heater.

FISAIR DFRB series dehumidifiers use a PTC (Positive

Temperature Coefficient) heater to heat the reactivation air with aluminium fins instead of a conventional electric resistance heater.

PTC heater is a semiconductor with variable electric resistance depending on its surface temperature. It is a ceramic polycrystalline compound, basically Barium

Titannate with self temperature limitation. When connected to mains the semiconductor surface reaches a maximum temperature of 230º C (aprox.), absorbing a variable electric power depending on the air flow that crosses through it. Typical operating diagrams of these heaters are:

Resistance

Temperature

Resistance-Temperature Diagram

Power

Air Flow

Power - Air Flow Diagram

PTC heater surface temperature self limitation effect provides the following advantages:

» Since the manufacture materials are designed to support the highest surface temperature, fire risk is limited even without air flow.

» The harmful atmospheric dust combustion doesn't happen.

» A limiting thermostat to protect heater is not necessary.

» Since dehumidification capacity is proportional to reactivation power and through the PTC heater this is proportional to the heated air flow, its reduction will proportionally decrease the unit capacity. This effect is inmediately and easily noticed at the integral ammeter of the unit when the wet air discharge duct is strangled or obstructed.

4.5 Regulation and control.

As a consequence of the PTC heater operation explained above, dehumidifier DFRB drying capacity can be regulated in two different ways:

!

On-Off Control: When you use the hygrostat terminals marked as H1 on wiring diagram, if the circuit is opened the PTC heater is switched off. The air on the unit keeps on blowing but it is not dehumidified.

When using connection marked as H2 on wiring diagram, if the circuit is opened the unit is completely switched off.

F

Note: The hygrostat must have a 10 A electric cut-off resistive capacity. Otherwise an auxiliary relay must be installed.

!

!

!

!

Proportional Control.- Other way to reduce the air heater power consumption and consequently the drying capacity of the unit, is to install a regulation damper in the wet air discharge duct. If the damper is driven by a proportional humidity controller, the dehumidifier capacity will be proportionally controlled in a modular way.

4.6 Options and ancillary components.

On demand, DFRB series of FISAIR dehumidifiers can be provided with:

Control Hygrostat On-Off.

Runtime Counter.

!

Manually or motor driven air flow regulation dampers.

Wall mounting or self carrier base.

5. Installation.

5.1 Location of the unit.

Before installing FISAIR dehumidifiers the following points should be considered

» If the dehumidifier has to be stored for a significant period prior to installation it should be protected from external damage and dust and construction material.

F

Note: In the case of outdoor storage, weatherproof covers should be employed.

» The FISAIR DFRB dehumidifier is designed for internal installation, for outdoor use please apply to your local representative for special construction details.

» Once final location is defined ensure that there is enough space for servicing to be carried out. Take care to ensure that ducting connections are made without stressing the unit.

5.2 Service Areas.

Using the attached dimensioned drawings of the relevant model, consider periodically:

» Air filters must be cleaned or changed.

» The desiccant wheel faces should be inspected and cleaned and the air seals adjusted as necessary.

» Driving belt should be checked for fatigue and its tightness checked.

» Check the operation of fans and motors and the reactivation heater. In case of failure, repair or replace.

» Check the components in the control box, service or change as necessary.

F

Note: To service/replace the main inside components, dismount the top cover and sided plates. This will provide enough space to service everything.

Pay attention to avoid that ducting connections and unit location do not prevent servicing.

WET AIR (ALWAYS SLOPED DESCENDING)

Different operation options of the unit as 'All Fresh Air' or 'Partial/Total Recirculation' systems and the possibility of mounting the unit inside or outside of the site which humidity is being controlled, determine the use of one of the above duct mounting diagrams:

!

In the diagrams are indicated two regulation dampers located at wet and dry air ducts used to adjust each circuit air flow and consequently the dehumidifier capacity.

Additionally, in the Partial/Total Recirculation diagrams you can see a third damper located in one of the process air inlets that can be used to over pressure the controlled site, minimising air infiltration from adjacent rooms.

The static pressure available for ducts can be found in the unit data-sheet.

Also, the wet air duct must facilitate the draining of the condensing water produced when this air becomes cooler

F-2833 - 8 - Technical Data Subject to alterations

Installation, Operation and Maintenance Manual

Desiccant Rotor Type Air Dehumidifiers DFRB series

due to heat transmission. To achieve this the duct must slope downstream and the wet air outlet must be placed as far as possible from the process air intakes, to avoid losses of performance.

5.4 Electric mains connections.

Attention: The dehumidifier works with medium electrical power and voltage and its connection to the mains must be done by qualified personnel and according to the applicable local electrical regulations.

The unit must be connected to the electrical network of the installation through a short circuiting and ground leakage protection line, with wires section/sensitivity as corresponds to the dehumidifier power.

5.5 Control equipment locations and connections.

The location and mounting instruction for the control equipment are normally specified by the corresponding supplier.

In case of On-Off Control using a Hygrostat you can choose between the complete unit switch off or the reactivation air heater switch off, as described before.

6. Start up.

6.1 Unit start up.

Once the ductwork has been completed and the equipment is connected to the electrical mains, as well as to the control equipment, proceed in this way:

Attention: Before using the control panel, verify that all mechanical elements can work freely and the unit has no installation d e b r i s inside.

» Check that the air flow regulation dampers, if exist, are opened.

» Check that hygrostat set point - if exists - is at least 10-

15% lower than environmental humidity.

» Check that electric mains is protected with a fuse adequate to the unit power.

» Switch on the unit. Integral pilot must light. Fan starts operation and the ammeter reading reaches the upper limit due to the PTC heater consumption. PTC heater, like motors, have a consumption peak on starting 2 or

3 times the normal consumption.

» Wait a few minutes allowing the desiccant wheel to rotate several times until drying and regeneration processes are stabilized. Check that dry air temperature is lightly higher than the process air temperature, and the wet air temperature is higher than the dry air temperature. Adjust air flows to specific requirements of each application.

» Measure foreseen thermohygrometric parameters.

To reduce the unit capacity you have to strangle the wet air stream, this automatically reduces consumption indicated by the ammeter.

6.2 Stopping the unit.

The equipment can be stopped manually or automatically.

Manual mode:

» Just operate the control switch to its "OFF" position.

Automatic mode:

» The unit will be shut-off when jumper H2, shown in the wiring diagram, is open (this stops the unit totally). In case of opening jumper H1, the reactivation air heater is shut-off while the two motors keep on running.

7.2 Corrective maintenance.

The (desiccant rotor type) FISAIR dehumidifiers series

DFRB have a very simple design and their components should have very few problems.

The fans/motors are of standard manufacture and in case of electrical or mechanical damages any skilled serviceman may do the repairing. The PTC heaters can be easily changed or serviced when necessary

(normally after a very long working period) like any other conventional air heater element (resistor).

Also, minor components like filters, dampers, driving belt and electric box components could be replaced after their useful life and the user will have to define the necessity of storing these parts, depending on their availability through local dealers.

7.3 Desiccant wheel service.

This is the only dehumidifier component that needs any special attention.

Concerning the mechanical operation, the rotor should not require attention for a very long time. Its rotation speed is so low (20-24 r.p.h.) that the bearings and desiccant material housing cannot suffer any mechanical damage normally. However, it is very important to verify periodically the correct operation of the driving device because it directly affects the drying process.

Regarding the water vapour adsorption process, the main rotor component, activated silicagel, works by fixing the water vapour molecules in its micropores in the process air stream, leaving them when the heated reactivation air stream passes through the rotor channels.

This process is not affected by the normal environmental air conditions, nor by accidents of the installation that can be expected (for example, water direct action on the rotor does not affect the material, which is also fireproof).

Usual dust deposits on rotor surfaces can be removed by vacuum or blowing as well as by washing (please contact your dealer for written method when needed).

8. Fault finding

Immediately switch off the dehumidifier if a fault occurs. Faults are only to be remedied by qualified personnel following the proper safety instructions.

Fault

The unit has stopped

The unit works, but it does not perform as expected.

Check the following points:

Measures

∑ Electric mains are powered and the pilot lights on. If not, reset the mains protections.

∑ If pilot lights on, check if the air has reached the hygrostat set point.

∑ If electric mains are powered, the hygrostat demands operation and the unit is not operating, please ask the dehumidifier supplier for technical assistance, since electrical components checking is to be to performed.

Check the following points:

∑ Wet air duct is not obstructed.

∑ Air filter is not too dirty

∑ Desiccant wheel rotates softly and continuously, and the rotor surfaces are not obstructed.

∑ The dry air outlet duct temperature is slightly higher than the process air duct, and the wet air duct temperature is higher than the dry air duct.

∑ Dry air and Wet air flow.

∑ If all this checking is successful, a measurement of the unit capacity must be performed as well as to review the single facility design parameters.
