Relative humidity and its effect on substances

All air contains moisture, sometimes more, sometimes less although the naked eye cannot see it until it condenses in small droplets on, for instance, a metal or glass surface. Already before it is visible however, the moisture affects substances and production processes, causes corrosion and microorganism growth.

Air humidity is measured and referred to in terms of Relative Humidity (%RH) which is the ratio between how much water it does contain and how much it can contain at given temperature and pressure. The higher the temperature, the more water the air can contain but it is still the Relative Humidity that is important and that needs to be controlled if one wants to prevent corrosion or mould growth.

At RH 100% the air is saturated – there is fog and the moisture condensates in small droplets. Already at RH 60% steel corrodes and at 70% there is a risk for mould growth. As a rule of thumb, RH 50% is a good climate for most substances.

How to select dehumidifier type

The adsorption principal has, compared to condensation drying, the advantage of a lower ambient temperature dependency. Adsorption functions even well below the freezing point while the capacity of a condensation dehumidifier inevitably decreases rapidly with falling temperature, something that is depicted in the diagram below to the left. As a rule of thumb, a general aid in the selection of type, it can be said that adsorption is the primary choice for drying of unheated spaces or when material is to be dried. Adsorption dehumidifier produces dehumidifier air, generates a greater reduction of water content measured in grams per

kilogram (Δx), and consequently creates a greater water vapor pressure difference which is directly

correlated to the drying speed. Drying of insulation such as floor structures are dried with combined use of turbines, high pressure fans, installed for either suction or pressure drying.

Condensation dehumidifiers are, in accordance with the diagram above, used in hot and humid conditions provided the goal and aim is drying of rooms, ambient air.

How the dehumidifier works

The desiccant used in the CTR A ES is silica gel which can be regenerated an almost infinite number of times. Silica gel is a crystal with enormous amounts of microscopic pores which makes its total surface very large, a single gram has an active surface of 500 to 700m2. Silica gel is very potent and can absorb water corresponding up to 40% of its own weight. It is not water soluble and can therefore not be washed away nor dissipate into the passing air.

Dehumidification process

The desiccant is placed in a rotor (1). The air to be dried is drawn through the inlet (2) by a process air fan (3).

The air passes a filter and then the rotor where after the dried air passes through the dry air outlet (4) and into the environment to be dried. The rotor has air channels parallel to its axis and is made from a highly potent desiccant, silica gel, fixed in a ceramic structure. The air channels in the rotor provide a laminar air flow with a low pressure drop.

The rotor is rotated by an electric motor (5) and a belt (6). The moisture that is adsorbed is removed by a small volume of process air that is heated (7) where after it is passed through a section of the rotor, thus regenerating it as well as cleaning it through the counter flow principle.

The wet air is evacuated through the wet air outlet (8).

Drying Methods

In the following the basics for the different drying methods that can be applied with the CTR A ES and applicable supplemental products from the Corroventa product portfolio are presented. The descriptions are merely overviews. Thus, if in doubt on how to proceed with given situation, consult experienced drying expert.

General drying, ambient air

An adsorption dehumidifier like the CTR A ES produces such dry air that a recirculation air flow rate of between one and two times per hour is sufficient, to be compared with three to four times which is suitable for a condensation dehumidifier. In other words, the CTR A ES which produces approximately 300 m3 of dry air per hour has capacity enough for a room of at least 50 – 60 m2 and a ceiling height of 2.5 meters.

As for all drying, regardless of type or model of machine used, it is important that the room or space to be dried is well sealed in order for the process to be as energy efficient and quick as possible. Windows and doors shall be shut and in absence of such delimiters, plastic foils or other temporary sealing should be used.

If the damage is limited and local, it is preferably sealed with plastic foil and a hose then used to lead the dry air in under the foil. By the edges of the foil small openings are left to let the air through and create circulation. This method makes the process go faster and thus consume less energy.

Drying of limited, local damage sealed with plastic foil in order to speed up the process and save energy.

Drying of floor structures

For drying of floor structures with easily dried insulation like glass wool or none insulated structures, the CTR A ES is with advantage used with a high pressure fan like the HP2000 in accordance with the schematic sketch below. Note that the capacity of the fan widely exceeds that of the dehumidifier and therefore the fan must not be directly connected to the dehumidifier by hose as this would seriously affect its function and degrade is efficiency. Instead, leave the dry air hose from the dehumidifier on the floor just by the fan so that the dry air is sucked in along with ambient air.

Drying of floor structure. Note that the dry air hose of the dryer on the right is not directly connected to the fan but left just next to its inlet.

Suction Drying

For suction drying of layered constructions such as floating floors, the CTR A ES is used with one or more turbines from the Corroventa product portfolio, in accordance with the schematic sketch below. The turbine or turbines are connected to hoses with filters and water separators through which they draw air from layered construction and then evacuate this, normally outdoors. The dehumidifier is placed in the room and its wet air hose installed to evacuate the wet air. The turbines will this way draw dry air down into the layered construction through drilled holes or through the gaps between the floor and the walls.

Note that, as mentioned above, a water separator must be used to avoid free water from being sucked into, and damaging, the turbine.

Suction drying. The dryer dries the ambient air and turbines draws and evacuates air from the construction. The resulting underpressure in the construction draws dry air into it.

Suction drying setup:

At the top, CTR A4 ES drying ambient air.

In the center, a CTR T4 ES turbine pulling air from the water separator. The turbine outlet shall be provided a hose leading to where the humid air from the construction can be released. The turbine is powered through the water separator power outlet.

At the bottom, a WS4 ES water separator connected to hose system with suitable number of distributed suction points so as to ensure air movement beneath the entire floor.

Use hose to release the humid air from the turbine outside the room.

Pressure drying

For pressure drying of layered constructions such as floating floors, the CTR A ES is used with one or more turbines from the Corroventa product portfolio, in accordance with the schematic sketch below. Pressure drying is two to four times faster than suction drying and is therefore, whenever feasible, the primary choice unless mould or fibres are present.

Pressure drying means leading dry air from the CTR A ES to a turbine and applying that to push the air into the layered construction. This way, hot and dry air will travel through construction making itstemperature rise which increases the speed of the drying process. Wet and cooled air exits the construction through drilled outlets or through the gaps between the floor and the walls and then returns to the dehumidifier as process air.

Before pressure drying is applied, suction drying should be used to evacuate any free water and prevent this from being pushed into other parts of the construction/building. When setting up the machines for pressure drying, it is very important to check turbine is not pulling more air from the dehumidifier than it can deliver. Therefore, always verify that the wet air volume is in balance with the dehumidifier. When using a CTR ES version turbine, this machine is preferably set to flow mode so that it maintains constant air flow. There is also the possibility of networking the two units, using the turbine as Master, and setting up the adsorption dehumidifier slave to pressure drying mode where it automatically adjusts the wet air volume to requirements. Still, always check the status of the units before leaving the site so that the installation works as intended. Furthermore, please note that the Extra Heater available with the CTR A4ESX must not be used when the dry air is led to a turbine as this will cause overheating.

Pressure drying might free particles/fibers from the construction and thus release them in the air. If this is a potential problem, another method, e.g. suction drying, should be applied.

Pressure drying. The turbine is fed with dry air from the dehumidifier and presses this air into the layered construction.

Installation

CTR A ES is placed and installed leveled and in a stable position so that it does not fall over and cause damage to the machine itself, person or property.

A hose is connected to the wet air outlet in order to evacuate the moist from the room or space to be dried. The wet air hose shall have a smooth interior surface and shall be as short as possible, no longer than 5 meters for optimal function and performance.

In the event of problems with condensate in the wet air hose these can, unless the hose can be shortened which is the best solution, be improved by a further small reduction of the dry air volume which will increase the dry air volume. The performance will be lowered so this must be considered and decided case by case. Another option is to make a small hole in the wet air hose and use a

bucket for collection of the condensate.

Installation in short, main points:

1. Place the dehumidifier where the wet air hose will reach the intended evacuation point.

Make sure that the dehumidifier is leveled and that it cannot fall over and cause damage.

2. Connect the wet air hose and lead it to intended evacuation point (hole in the wall or

window etc. Verify that the hose is not squeezed or bent to sharply but that it will allow for unobstructed wet air flow.

3. Verify that the wet air throttle is fully open. For normal drying of ambient air, both dry air

throttles shall be fully open too.

4. Connect the cable to a 1-phase, 230 V AC socket with a 10A or maximum 16A fuse. As the

machine is normally used in humid or wet spaces, the use of a ground fault circuit interrupter is strongly recommended.

5. Start the machine using the power switch. When the display lights up, in the first screen

presented after the start-up, push Start.

6. Allow for the machine to warm up for a few minutes.

7. In order to optimize the operation of the machine, push the top right button three times to

enter the Capacity menu. At the bottom of the screen, there is a wet air level indicator showing current operation. Slowly, use the dry air throttle to adjust the flow so that the indicator is centered on the dashed line for optimum performance.

The wet air shall always be evacuated from the room/space to be dried.

Control Mode

The Control Mode determines whether the drying shall be continuous (MAN – manual mode) or if it shall operate only when required as determined by the ambient climate.

The selected control mode is displayed in the lower left corner of the default view.

The Control Mode selection screen is reached by one push of the upper right button.

The following basic control modes are available:

MAN

Manual, continuous drying.

Drying down to selectable Relative humidity, %.

MIX

Drying down to selectable mixing ratio, g/kg.

DEW

Drying down to selectable dew point, °C

HYG

Drying controlled by external hygrostat connected to the machine.

Through its network capabilities, the machine can also connect to external RHT sensors and use their values to control the operation rather than using the built-in Relative Humidity and Temperature sensor. For this purpose there are also the following External sensor modes:

E.RH

Drying down to selectable Relative humidity, % as given by external RHT sensor(s) connected to the machine.

E.MIX

Drying down to selectable mixing ratio, g/kg as given by external sensor(s) connected to the machine.

E.DEW

Drying down to selectable dew point, °C, as given by external sensor(s) connected to the machine.

The External control modes require the machine to be networked and connected to an external RHT sensor. If the machine is not networked already, the machine will ask if it shall create a network. If there are multiple sensors in the network and alternative <All< is selected rather than one unique sensor, e.g. RHT61, the machine applies “worst case” and operates as long as any one of the sensors read a humidity above the setpoint.

When selecting mode other than MAN, the machine presents the user with the possibility of determining the setpoint.

When reaching the setpoint level, the drying automatically stops. Should the humidity later on rise above the setpoint level, drying operation is automatically resumed.

Hysterisis

When selecting RH, DEW or MIX control modes, to the right in the display there is a symbol and a hysteresis value presented. The symbol indicates the position of the setpoint in the operation span as presented below.

↕ - center

↓ - bottom

↑ - top

Fan Mode

The Fan mode determines whether the fan in the dehumidifier shall operate continuously or if it shall operate only when drying is required and ongoing.

If continuous fan is selected, the word CONT is presented in the lower right corner of the default screen.

If possible, for optimal drying effect, use continuous fan to keep the air in constant motion.

Page 20

2017.05

Capacity Mode

The drying capacity of the CTR A ES can be optimized to the given work and situation by use of three different operation modes. When set to MAX, maximum, the machine operates to remove as much water as possible. When the full effect of the machine is not required, it can instead be set to ECO, eco-mode, where the energy consumption per liter of removed water is minimized. For local water damages where the dry air volume is not required, the machine can be set to one of its ΔX modes where it operates to produce a smaller volume of even drier air, something that will further increase the speed of the drying process. The difference

between ΔX1 and ΔX2 etc., is the dry air volume where ΔX1 has the lowest volume.

For use during pressure drying when the machine is slaved to a turbine on a local network, the CTR A ES also has a pressure drying mode, PRS, where it automatically adjusts the wet air flow to produces as dry air as possible.

MAX

For maximum water removal

ECO

For minimal energy consumption per liter water removed

ΔX1, ΔX2..

For maximum ΔX, as dry air as

possible. Reduced air volumes suitable for, for instance local, sealed of water damages.

PRS

Pressure drying mode that can be used when the machine is connected to a network and slaved to a turbine.

When the machine is installed and started up and whenever the capacity mode is changed, the wet air flow needs to be adjusted for optimum performance. When the capacity mode is changed, the machine will guide the user through the procedure as depicted to the right. If the wet air hose is long, it might be necessary to reduce the dry air flow somewhat in order to achieve the correct wet air volume. Normally however, adjusting the wet air throttle is sufficient to achieve required wet air volume. When adjusting the wet air flow, adjust slowly the throttle slowly and allow for the indicator to stabilize before evaluating whether the adjustment was sufficient or if further increase or decrease is required.

Extra Heater CTR A4ESX

The CTR A4 ESX is equipped with an Extra Heater increasing the temperature of the dry air and thus further improving the drying effect.

When this function is selected, there is an Extra Heater icon in the default view below the fan symbol. Naturally, the Extra Heater is only active when the fan is active.

Note: The Extra Heater must not be used if the dry air is fed into another machine as this could cause overheat.

Timer

The CTR A ES has built-in timer functionality allowing the user to determine when the machine shall operate. When Timer function is used, the word Timer is presented in the top right corner of the default view as can be seen to the right.

To activate Timer, push the right arrow button four times to enter the Timer menu. Push Activate.

When timer is activated, as a first step, the machine asks the user to verify that its time and date settings are correct. If so, push OK. If changes are required, push edit to do the required changes before continuing.

In the next step, the user is allowed to set the time interval within which the machine shall operate. The machine remembers the timer settings from last time it was used and presents that data as default. The Outside int. setting determines whether, for the remaining hours of the day, the machine shall remain in stand-by or if it should operate with a lower fan speed so as to minimize the noise.

Network

Note: Install all the system cables before powering up the machines.

The CTR A ES is equipped with networking capabilities enabling local cooperation between the machines such as pressure drying as well as the use of external Relative Humidity and Temperature sensors for control of the machine. The networking capabilities are also a preparation for a future SuperVision system that will enable remote monitoring and control of the machines through Internet.

In order to establish a network, install the machines as intended and connect the with system cables before powering them up. On the machine intended to be Master, to be in control of the others, enter the Network menu. Push Create and wait while the machine establishes the network which can take up to a minute.

Once established, in the network menu, the presentation will toggle between the slave units which are referred to with type, for instance A4, and address on the bus, for instance 101.

In order to change the settings of a slave unit, press Edit and the select the given slave. As a confirmation of what unit was selected, the display backlight of the selected unit will start blinking.

The desired settings can still also be made on the respective machines themselves.

When all desired settings are made, start the Master machine and the slaves will be started automatically within a minute. Similarly, when the machines are to be stopped, push Stop on the Master machine and the slaves will soon stop automatically.

As the Master machine is controlling the network, if a slave unit is started manually when the Master is in standby, the slave unit will be stopped. Similarly, if a slave unit is manually stopped while the Master is running, the slave unit will be started again.

Alarms

In this screen, the machine presents identified alarms. As soon as an alarm is identified, this is also presented as a pop-up screen. Furthermore, as long as the error condition remains, in the top right corner of the default view there is an warning symbol.

The alarms presented need not be erased by the user. Instead, as soon as the machine detects that the functionality is again in place, the alarm will disappear automatically.

Control Modes and Hysteresis

In addition to normal, continuous drying operation, the CTR A ES operation can be controlled by use of its internal Relative Humidity and Temperature sensor, external hygrostat or external, networked sensor.

When using an electronic sensor, built-in or external, the machine applies a software controlled hysteresis to make the operation of the machine stable and prevent excessive on- and off -switching.

The table below presents the default settings of the machine. If changes are required, these can be made under the Setup and Maintenance menu.

MID ENERGY METER MENU

Part of the main menu loop and accessible with either of the navigation keys, the MID Energy Meter menu presents the total, accumulated energy consumption. The affixing, M18 in the example below, as well as the serial number that follows is information on the built-in CEMP energy meter. The revision number given at the bottom row refers to the legally relevant firmware within the machine.

The integrity of the data presented with this menu is thoroughly checked and protected. One such important test is the calculation of a checksum to verify that the program memory has not been corrupted. The result of the latest calculation is always available with the Firmware checksum screen, accessed through the MID Energy Meter menu with the lower right button.

If any of the tests fail and the machine concludes that the available energy meter data must not be trusted, the information is removed from the screen and replaced with dashes. If the problem detected has to do with the checksum calculation, the bottom row of the screen will say so.

Left: Data removed due to communication error

Centre: Data removed due to checksum error

Right: Appearance of Firmware checksum screen when error is detected.

Network functions

As a member of the new CTR ES family of machines, the CTR A ES can be networked with other turbines and adsorption dryers which provides extended functionality including:

• Relation – cooperation between two or more turbines with defined relation between the

respective air flows.

• Optimized pressure drying, a mode of operation where the slaved adsorption dryer

automatically adjusts to the turbine air flow producing as dry air as possible.

• Operation on common timer

• Interoperability with future SuperVision system allowing remote monitoring and control of

machine operation.

The networking of machines requires no pre-configuration or other preparations. When installed, the machines are simply connected with system cables and then a simple push of the Create button in the Network menu of the intended Master machine is all that is required. The Master is the machine selected to control the others and all machines can be used to this purpose. For use of Relation and Pressure drying modes, the Master needs to be a turbine but for other purposes it does not matter what machine is Master on the network.

While a machine is slaved to another unit, its settings can still be changed on the machine itself and not only through the Master. If the user selects to do necessary changes to the settings through the Master, the display of the selected Slave flashes while the changes are made so as to allow for easy identification and avoid confusion.

How to network machines

In order to network machines to use for instance the pressure drying mode of the dehumidifier, proceed as follows:

1. If the machines are powered, switch them off and then proceed by connecting the machines

with system cables. The two connectors on the machines have the same functionality so it does not matter which one is used. If SuperVision is to be used, this too must be connected to one of the machines, it does not matter which one.

2. Power up the machines.

3. Select what machine shall be master, for use of pressure drying mode, this shall be the

Turbine set to push the dry air into the construction. If networking the units with the only purpose of having them monitored and remotely operated through SuperVision, it does not matter what machine is selected as Master.

4. On the selected Master machine, use right arrow button to step to the Network menu

depicted below.

(If this menu is not found, the machine is set to Basic menu setting. To change this, select Setup and Maintenance menu and change the menu system setting to Advanced.)

5. In the Network menu, push <Create> and then wait while the machine sets up the network.

6. When the network is created, at the top of the screen the presentation will toggle between

the different slaves. If SuperVision is connected, the text SuperVision will be presented at the bottom of the screen although it can take up to a minute before this is shown.

After having followed the steps above, all the slave machines are now controlled by the Master. This means that they will all be started and stopped with the Master. They still work with the same settings they had before the network connection so if these need to be changed, push Edit and then select the slave to be edited through the Master or do the necessary changes to the settings on the machine itself. When being edited through the Master, the slave machine will start to blink its display backlight so that the user can see what machine is selected.

Service Reminder

The machine is set to provide a service reminder every twelve months. The reminder is presented as an alarm but it does not affect the operation of the machine. The service reminder function is reset under Setup and Maintenance.

Maintenance and service

Filter replacement

The dehumidifier’s process air filter shall be replaced regularly in order to maintain energy efficiency and to avoid overheating, suitably between every installation, every work, that the dehumidifier is used for. When used in dirty environment, the filter needs to be replaced more often.

1. Disconnect power to the dehumidifier - remove its cable from the socket.

2. Turn the knob of the filter hatch anti-clockwise to open it. Pull out the dirty filter and insert

the replacement filter. Close the hatch by turning the knob clockwise.

3. Reconnect power.

Turn anti-clockwise to open filter hatch.

Cleaning of rotor

When required, yearly or after use in very dirty environment, it is recommended to clean the rotor with pressurized air. The rotor can be clogged by dirt resulting in lowered air flow and capacity. To clean the rotor, follow these instructions:

When the rotor shall be cleaned, the dehumidifier must be disconnected from power.

Always use a suitable protective mask and stand outdoors when cleaning the rotor.

Make the machine powerless.

Remove the four screws that hold the top lid of the dehumidifier.

’

1. Gently lift the lid enough to reach and

disconnect the three cable connectors that are positioned along the front of the machine. Note: The connectors have clamps that lock them into place and these need to be pushed while the connector is pulled out.

Page 33

2017.05

32 (43)

2. On the A4ES or the A4ESX, reach into the

machine between the fan and the rotor assembly and pull the internal wet air hose off the spigot. Pull the entire rotor assembly upwards to lift it out of the machine. Be careful not to damage the rotor.

On the A2ES, it is easier to remove the fan gable. Remove the two screws that hold the fan gable in place, found between the feet of the machine. When the screws are remove, pull the fan gable upwards and remove it.

3. On the rotor assembly, push the tensioning

wheel back and slide the belt off the wheel so that the rotor can be turned freely.

4. Note: Always use a suitable protective mask

and clean the rotor at suitable location outdoors.

With pressurized air, carefully blow the rotor interior clean. Hold the nozzle approximately 15cm from the rotor and begin by blowing from the heater cover side of the rotor. This way, the air will flow through the rotor in the opposite direction of what it usually does which will prevent further dirt from getting stuck inside. When later cleaning from the other side, avoid blowing into the heater cover as the dirt will collect inside. Only blow on the rotor where the opposite side is free and unobstructed.

5. When the rotor is cleaned, assemble the

dehumidifier in the reverse order, thus:

• Mount the belt

• Carefully lower the rotor assembly

into the machine.

Page 34

2017.05

33 (43)

• Reattach the wet air hose. On the

A2ES, put the gable back in place while sliding the hose onto the spigot of the heater cover on the rotor assembly.

• Put the lid back on the dehumidifier,

re-connect the three cable assemblies. Mount and tighten the four screws.

6. Inspect and verify the good function of the

dehumidifier as follows: Connect power to the dehumidifier and put it in manual mode. Verify that it starts, that the fan starts running. Verify, by looking into the wet air outlet that the rotor is rotating. Put one hand in front of the wet air outlet and verify that the air feels warm, thus that the heater is functioning.

Fault finding

Symptom

Probable cause

Action

Room is not getting dehumidifier/low capacity.

Depending on the situation, the cause of the problem can be either incorrect installation such as obstructed wet air hose, clogged filter, incorrect settings to the machine or machine failure.

Begin trouble shooting as follows until the problem is identified:

Check the installation – verify that the wet air hose is not obstructed, that the dry air throttles are in their intended position and that any hose used on the dry air side too is not squeezed or clogged but that the air flow seems correct. If the air flow is weak, check and if necessary replace, the process air filter.

Check the settings of the machine as follows:

First, check that the water symbol in the left part of the screen is moving, an indication of on-going dehumidification. If it is not moving, check the control mode in the lower left corner of the display. For continuous drying, this should read MAN for manual mode. If external hygrostat is connected and used, HYG mode, check the setting of the hygrostat. If RH, DEW or MIX control mode is used, check the setpoint highlighted at the center of the display and adjust as required. Verify that the water symbol starts moving.

If the control mode and its settings was not the problem, continue by checking the capacity mode presented in the top right corner of the default view. For maximum water removal, the text should read “MAX”. ECO mode is for minimizing energy consumption per liter water removed and

the ΔX modes are used for, for instance,

drying of local, sealed of water damages. If required, use right arrow button to step to the capacity mode menu and change mode. Follow instructions presented for adjustment of wet air volume.

Page 36

2017.05

35 (43)

Immediately after the capacity mode name,

there is a symbol, either ↕, ↑ or ↓. The first

symbol, the ↕, indicates that the wet air volume is correct, in balance. The down

arrow, ↓, means that the wet air volume

should be decreased and the up arrow means that it should be increased. If the wet air volume is incorrect, use right arrow button to proceed to the capacity mode menu and use the wet air meter as guidance while adjusting the wet air throttle.

The rotor is rotating anti-clockwise as seen through the dry air outlet or doesn’t rotate at all.

Rotor motor or the motor capacitor is faulty.

Contact your retailer for repair.

No air is blowing, the fan is not running.

The machine has been set in standby.

The dehumidifier is set to a control mode other than MAN, manual, continuous fan function is off and the ambient humidity is so low that the machine is now in standby.

The machine is operating on timer and currently in standby.

Push either Start to start the machine with default settings or Resume to start with the previous settings.

Check the control mode in the lower left corner of the machine For continuous operation, it should read MAN as in manual mode. If other mode is used, check the setpoint. For continuous fan, use right arrow button to step to the Fan mode menu and activate Continuous fan.

If applicable, adjust the set point of the humidistat.
