6 Description of the Appliance 8
6 Description of the Appliance
The CDF/CIF-Freeze-Thaw testing equipment (CDF machine) is a high-
quality testing device for carrying out freeze-thaw resistance tests on
building materials. CDF machine is equipped with a microprocessor
controller including internet interface. All relevant safety regulations for
refrigeration and electrics have taken into account.
The CDF freeze-thaw testing device enables the implementation of the
freeze-thaw resistance test according to RILEM Recommendation (Ma-
terials and Structures (1996) Vol. 29 (193), pp 523-528), according to
RILEM CIF test and according to CEN/TS 12390-9. The advantage of
these test methods lies in the very good reproducibility of the measure-
ment results.
These test methods describe the periodic freezing of building materials
through indirect contact with a heat transfer fluid. This arrangement en-
ables an optimal temperature distribution, a fast temperature adjustment
and a temperature gradient perpendicular to the tested surface. Due
to the optimal thermal contact, the temperature can be maintained very
accurately over the entire temperature curve.
The CDF machine is cooled by means of air cooling. Optionally, the ma-
chine can be equipped with a combined air-water cooling „Additional
Feature Air and Water Cooling for CDF equipment“.
With a appropriate system upgrade, the cube test (VDZ cube method) in
accordance with CEN/TS 12390-9 and the ASTM test in accordance with
ASTM C666 procedure A can be carried out („Additional Feature Cube
Test and ASTM C666 Procedure A“). In contrast to air conditioning
cabinets, the freeze-thaw cycle can be run through in 12 hours instead
of 24 hours due to an efficient heat transfer from the heat-transfer fluid
to the sample. Hence, testing time and costs will be minimized.
The technology of the system is easily accessible from all sides due
to removable panels. A thick, carefully executed pipe insulation and a
cross ventilation of the device parts reliable prevent condensation. All
components fits well due to the use of CNC punching and CNC bending
presses. Robust surfaces result from powder coating of all sheet metal
parts.
The CDF machine is supplied as a plug-in compact device in chest form.
It consists of three main parts: testing bath, refrigerant equipment and
controller unit (fig. 1).

The tub of the testing bath is thermally insulated and is made of high
quality stainless steel. For the uniform temperature distribution in the
testing bath, the cooling liquid is kept flowing. The sample containers
are made of stainless steel and are placed in the cooling bath. The
concrete samples are placed in the sample containers. The buffer with
the heat transfer fluid is placed directly under the testing bath.
6.2 Refrigerant Equipment
The unit part, which contains the refrigerant equipment and the assem-
blies for circulation and temperature control, is located below the testing
bath (fig. 1, (3)).
The temperature bath is circulated with a pump and thus enabling rapid
temperature control. If the temperature bath is to be heated up, the
heating is switched on. If the temperature bath is to be cooled, pre-
cooled heat transfer fluid is taken from the storage bath and fed into the
main circuit.
The temperature in the storage bath is always kept well below the target
temperature of the testing bath so that a sufficient amount of cold is
available.
6.3 Controller Unit
The controller unit contains the regulation and switches of the machine
and is attached to the right of the machine (fig. 1, (4)). Disconnect the
power supply before maintenance work. All installation and maintenance

7 Delivery and Installation 14
7.2 Spatial Requirements
The CDF machine is designed for operation in closed rooms. The envi-
ronmental conditions should be at minimum +5 °C to maximum +28 °C
and relative humidity of maximum 65 %. At higher humidity, more con-
densation may occur on some parts of the machines. For the tempera-
tures above 28 °C additional water cooling system is required.
The CDF machine is engineered in accordance with DIN EN 378-1 class
A. This means it is allowed to operate the CDF machine in a room where
people are sleeping, disabled persons are working, or a lot of not in-
structed people are present. So there are no special requirements in the
training of the people working with, or nearby the machine.
The floor should be designed for a load of at least 300 kg/m2. For a
purely air-cooled system, the room size should be at least 200 m3and
be well ventilated to dissipate the waste heat. For the set up of the CDF
machine, please ensure free air circulation around the equipment.
The installation area required for the CDF machine is shown in fig. 5.
Figure 5: Required area for the installation of the CDF machine.
7.3 Transportation
For the transportation of the CDF machine, remove sample containers
and the cooling liquid from the bath and the storage tank (buffer) when
filled (see also chapter 10.5).
Only attach the system to the frame of the chest and avoid exerting
any force on the side (trim panels) of the chest or the controller unit.
The trim panels should be additionally secured or transported extra.
The dimensions and the balance point of the equipment as well as the
points of support for the forklift are shown in the figure 6.
If no frost-proof transportation is to be expected, the residual water from
the water-cooled systems must be drained from the plate heat exchanger

nician to perform this work.
Figure 6: Dimensions (in cm) and balance point of the CDF machine.
7.4 Turn on the Equipment
Make sure incoming voltage and frequency are the same as the equip-
ment rating. This information is printed on the type label and can be
found on the CDF machine in the area of the power cable.
The CDF machine requires a 5-pin Euro power socket and 400 V three-
phase power network with a rating of 3x32A CEE32A (3x25A charac-
teristic B) and an appropriate circuit protection. Direction of rotation is
right.
Connect the power supply by a red 3PH+N+PE plug and turn on the
equipment. The display is on.
The main switch of the system should be switched on preferably 12
hours before starting testing. The compressor heater is then activated.
The warming up prevents overpressure failure of the compressor after a
long standstill.

7 Delivery and Installation 16
7.5 Filling the Equipment
Set the CDF machine in level before filling the bath. Check this by a level
at the testing bath (7). If necessary, the device can be levelled with four
adjustable feet. It should be adjusted to ±1 mm/m exactly.
Figure 7: Level check.
Insert the filter through the drainage openings in the testing bath (fig. 8,
left).
Fill the heat transfer fluid (water-glycol mixture) into the testing bath.
The filling quantity of the equipment in approx. 100 litres and depends
on the number of sample containers in the testing bath. Hang up the
required number of sample containers in the testing bath and fill up the
heat transfer fluid to the optimum level (fig. 8, right).
Turn on the pump „PU 1“ for the testing bath and pump „PU 2“ for the
buffer from the menu Setup →System Menu →Manual (see chapter
8.5.5). If need, turn the pumps on and off several times until the circuit
remains stable. For pumping the heat transfer fluid from the buffer into
the testing bath activate „Y-K1“ from the menu „manual“.
Never run the pumps for long time without fluid. Always make sure that
the pumps are not sucking in air.

7 Delivery and Installation 17
7.6 Cooling Water Connection for the Combined Air-Water-Cooling (optional)
If the CDF machine is equipped for the combined air-water cooling, it
can be supplied with cooling water via 1/2“hoses. When connecting,
pay attention to the flow direction (fig. 9). The hoses can then be passed
under the machine.
On-site installation of manometers in the water inlet and water outlet, a
water meter and a water filter with a mesh size of 0.1 mm are recom-
mended.
The water inlet pressure should be between 1 and 10 bar.
The regulation for the cooling of the CDF machine is set via pressure of
the condenser. For the pressure of the condenser between 15 and 16
bar air cooling takes place. Higher temperatures due to the environment
or inefficient ventilation and heat dissipation cause higher pressure of
the condenser. If the pressure of the condenser rises to 16 bar and
higher, the water cooling switches on additionally.
All changes to the settings must be carried out by a qualified technicians.
Contact your customer service or Schleibinger for questions.

7 Delivery and Installation 18
7.7 Cube Test and ASTM C666 Procedure A (optional)
The equipment may optionally be used for the cube testing method ac-
cording CEN/TS 12390-9 or for the testing method according to ASTM
C666 procedure A. Both methods require a higher filling level of cooling
liquid and a higher heat output. For the conversion, proceed as follows:
• Remove the filter and screw on additional sequence pieces includ-
ing the sealing of the drain in the testing bath to reach a level of
100 mm. Put the filter back in.
• Place the majority of the sample containers in the testing bad and
add heat transfer fluid until the optimum fluid level is reached.
• Check from the menu Setup →System menu →Misc. additional
sensor Ad. Sensor is activated.
• Choose the suitable profile in set-up menu: profile for cube test
method (VDZ12 or VDZ24) or profile ASTM 666 for test profile ac-
cording ASTM C666 procedure A.
This option is characterized by a higher heating output. The heating pa-
rameters can be changed using the controller parameters. Select from
the display Setup →System Menu →Controller →Bath →VDZkr.
The number means the temperature difference between the current tem-
perature and the set temperature and should be between 1 and 5. For
the input number of 5, the heating switches on when the difference be-
tween the current and set temperature reaches 5 °C. For carry out the
freeze-thaw test according to ASTM C666 Procedure A or Cube Test ac-
cording to CEN/TS 12390-9 usage of the temperature difference of 2 °C
is recommended (fig. 10).
The CDF machine equipped with this option is factory set. No changes
are required for heating operation.
