User Manual CTR T ES
Intended use
The CTR T ES, including the CTR T2 ES and the larger CTR T4 ES, is the first digital turbine family
developed and intended for construction drying and water damage restoration where the machines
are used for suction and pressure drying in combination with adsorption dryers.
Through its control panel, the CTR T ES provides the user with the ability to set desired air flow,
resettable energy and time counter as well as timer operation. Part of the new CTR ES family, the
CTR T ES is also capable of networked operation and it is prepared for remote monitoring and control.
The unit has cable parking integrated with its foldable carrying handle and its low weight makes it
easy to carry and install. Durable yet flexible feet protect floor surfaces while also allowing stacking
of machines. The turbine is naturally as robust in its design as its predecessors, a prerequisite for a
long service life. Thanks to the very low noise, it can be used for both construction drying and water
damage restoration without the occupants having to evacuate.

Relative humidity and its effect on substances
All air contains more or less moisture but 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 micro organism growth.
Air humidity is measured and referred to in terms of relative humidity (%RH) which is a measure how
much water it contains relative 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 dryer 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 dryer 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. The latter is motivated by the
fact that the adsorption dryer produces dryer air, generates a greater reduction of water content
measured in grams per kilogram (Δx), easily deduced from the diagram below to the right and
something that is directly correlated to the drying speed. Drying of layered constructions such as floor
structures are, with advantage, dried with combined use of turbines, high pressure fans, installed for
either suction or pressure drying.
Condensation dryers are, in accordance with the diagram above, used in hot and humid conditions
provided the goal and aim is drying of rooms, ambient air.

Drying methods
The turbine CTR T ES is, in combination with adsorption dryer, used for suction and pressure drying.
The reason for the use of an adsorption dryer is that both suction and pressure drying are all about
drying material and the speed of that process is dependant of the difference in water contents (Δx),
measured in grams per kilogram, between the material and its environment. Adsorption dryers
produce dryer air, generates a greater reduction of water contents measured in grams per kilogram)
which increases the speed of the drying process. With pressure drying, warm and dry air is pressed
down into the construction making the construction temperature rise which increases the speed even
further and is the reason for it being faster than suction drying.
Suction drying
For suction drying the turbine is installed so that
it draws air from the construction through hose,
water separator and filter and then evacuates
this, normally outdoors. Use of water separator is
critical to prevent water from being sucked into
the turbine and damage its motor.
The dryer is installed for normal drying of room.
Pressure drying
For pressure drying, the turbine is installed so that
it is fed with dry air from the dryer and then presses
this down into the construction. This makes the
construction temperature rise and the drying goes
faster. Wet and cooled air leaks into the room
through drilled holes or gaps between the floor and
the walls and then returns to the dryer as process
air.
Before pressure drying is applied, suction drying
shall be used to remove any free water from the
construction and thus avoid pushing this into other
parts of the building. The initial removal of free
water also saves time.
Pressure drying might free particles/fibers from the construction and thus release them in the air. If
this is a potential problem, another method should be applied.
Pressure drying. The turbine is fed with dry air from the
dehumidifier and presses this air into the layered
construction.
Suction drying. The dryer dries the ambient air and the turbine
draws and evacuates air from the construction. The resulting
underpressure in the construction draws dry air into it.

Installation
The CTR T ES shall be 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.
For suction drying, a water separator shall be used and connected to the hose prior to the turbine so
that water is not sucked into the turbine as that will damage the motor.
For pressure drying it is important to verify that the capacity of the turbine does not exceed that of
the dryer, that the latter’s dry air volume matches the turbine’s throughput. If not, too much air will
be drawn through the dryer and its capacity will decrease dramatically. If using a CTR ES version
dryer, this is verified by observing that the wet air volume is correct. When using one of these
machines, there is also the possibility of networking them, using the turbine as Master, and setting
the slaved adsorption dryer to pressure drying mode. In this mode, the dryer will automatically adjust
to the air volume that the turbine is pushing.
Verify that the cooling air filter is clean and not clogged by dirt. If required, replace the filter before
the work is commenced.
Contrary to its predecessors, the CTR T ES is not equipped with a manually resettable overheating
protection as this no longer is necessary. The turbine provides itself with cooling air and prevents
overheating by automatically adjusting its speed if the temperature should still rise too high. For best
drying performance, the user should however still verify that the airflow through the construction to
be dried is correct.
Installation in short, main points:
1. Put the turbine in a leveled and stable position so that it does not fall over and cause
damage.
2. Check the process air filter and the cooling air filters and replace them if necessary. Connect
the hoses configured for the drying to be undertaken. If free water might be present in the
construction to be dried, use Water separator to prevent water from being sucked into the
turbine.
3. Connect the cable to a 1-phase, 230 VAC 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.
4. Put the power switch in position On. When the display has started up, for new job with
default settings, push Start. To operate with the same settings as last time the machine was
used, push Resume.
5. Adjust the speed until desired air flow is obtained.

Accessories and consumables
The following articles are available as accessories and consumables to the CTR T ES:
To Use CTR T ES, menus and operation
The CTR T ES has an easily understood user interface with a display and five push buttons. The two
larger buttons on the respective sides of the display are used to select between the different menus
– no changes to the setup can ever be made with these buttons as they are for navigation only.
The three smaller buttons below the display are used for selection and editing. At the top level
menus, the left of these buttons is named Home and a push on this button will immediately lead
back to the default view, something that can be good to remember if unfamiliar with the menu
system. In many of the views there is an Info button which presents information that may be of use
to the inexperienced user.
If the backlight of the display has timed out, the first button push serves only to light up the display.
After 10 minutes, if no button is pushed, a key pad lock is activated. The machine is then unlocked by
simultaneous push of the two upper buttons, something that is presented in text as well as picture
on the display.

Start up view
When the T ES starts up, the display presents the user
with two options:
Start:
Starts the machine at default speed. Previous
settings made such as Timer and Flow settings are
discarded.
Resume:
The machine resumes operation with the
settings it had last time it was used.
If, last time it was used, the user never pushed stop
before the power was cut, the machine will
automatically resume operation when the countdown
has reached zero.
Normal start
Start med timer
Default View
When the T ES is operating, the machine can always be
stopped, set to standby, by use of the center button
below the display.
When the Turbine is operating on fixed speed, the left
and right buttons below the display are used to
decrease and increase the speed level. The current
speed level is depicted on the vertical bar to the left.
The horizontal indicator presents the current pressure
level compared to the maximum pressure achievable
for the given turbine speed.
When set to flow mode, the left and right buttons
below the display changes the setpoint flow,
highlighted with black background. The same principal
applies to Relation mode which can be used when the
machine is used in a network and slaved to another
Turbine.
Control Mode
The machine can operate in three different control
modes, Fix, Flow and Relation. In Fix mode, the user
selects a fixed speed level for the turbine. In Flow
mode, the user instead selects what air flow shall be
maintained and the machine will then automatically
adjust the turbine speed to maintain that airflow even
if the counter pressure changes.
The third option, Relation, is only available when the
machine is networked and slaved to another turbine.

The Relation mode functions like the Flow mode, the
only difference being that instead of defining a certain
air flow, the user selects what percentage of the
Master machine’s air flow the turbine should maintain.
To select Control Mode, push Change and then use the
right down arrow button to select mode. Push OK to
confirm the selection. In the next step, adjust setpoint
as required.
The current Control Mode is displayed in the top left
corner of the default screen.
Water Separator
Note:
This functionality can only be used when the
turbine is connected to a WS4 ES Water Separator.
If the turbine is connected by power cable and by
system cable to a WS 4ES, the turbine can register how
many times the water separator is emptied so as to
allow the user to calculate how much water has been
removed. In addition, the turbine can also present at
what date and time the water separator was last
emptied in order for the user to assess whether or not
there is any more water to be removed.
If this functionality is activated there when there is no
WS 4ES connected, the turbine will remain in standby.
Timer - on/off and quiet mode
If, for some reason, the machine must not operate
continuously but for instance only day time or night
time, the machine can be set to operate on Timer.
For the remainder of the time, the machine can be set
to turn off completely or to operate in quiet mode.
In quiet mode, the speed of the turbine is reduced to
approximately level 4 in order to minimize noise.
When Timer is selected, the word Timer is displayed in
the upper right corner of the default screen.
To activate Timer, enter the Timer menu and push
Activate.
Confirm or, if required, edit the system time and date
which is presented in the following format:

Network functions
As a member of the new CTR ES family of machines, the T 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.
