DIP AND FLOW COOLERS USER’S MANUAL
INTRODUCTION
Read the whole of this book before commencing work with the unit.
The book applies to a range of Techne fridge units, Dip Coolers RU200 and RU-500 and Flow Coolers FC-200 and FC-500. Hence
paragraphs or sections without a heading or reference apply to all
units while paragraphs or sections with headings apply to specific
units. For Refrigerated Baths there is a separate booklet.
The Techne fridge units are designed to cool liquids to temperatures
around ambient and below by extracting heat continuously. The
temperature is controlled by a temperature controller with a heater
adding heat as necessary. Depending upon the circuit and the
application this could be a Techne Thermoregulator, TE-10 series or
TU-20 series, or it could be a Techne Circulator, the C-85A or C85D. Each unit, fridge or controller, has its particular application
which should be considered when setting up a temperature
controlled system.
Dip Coolers
The RU-200 and RU-500 are designed to work with Techne
laboratory baths and thermoregulators without reducing the working
area of the bath. They consist of a refrigeration unit where the
evaporation coil is on a flexible hose. The coil is placed in the liquid
and heat is extracted as the coil cools. The Dip Coolers work most
efficiently when the liquid flows over the coil.
The Dip Coolers are designed so that the cooling coil fits in the
corner of a Techne bath supported by a special cover on the bridge
piece. However they may be used in any bath but the flexible hose
must not be allowed in the liquid.

DIP AND FLOW COOLERS USER’S MANUAL
Flow Coolers
The FC-200 and the FC-500 are designed to work with the Techne
C-85 circulator to give the temperature control. They are normally
used to give circulation round a closed loop system, but may also be
used in the open tank situation where the use of a dip cooler is
impractical.
The Flow Coolers use a refrigerant which is circulated through a
compact heat exchanger which has inlet and outlet pipes for the
working liquid on the rear of the unit. These pipes are 16mm
diameter. The flow coolers need a minimum flow rate of 10 litres/
min at 20oC to prevent freezing in the heat exchanger.

Siting Considerations
All the units are air cooled, air being pulled in through the front and
expelled from the rear. The ventilation grilles should never be
obstructed, therefore, as this will detract from the performance. Also
the fridge units should never be situated in an enclosed space or
near an extractor fan, this too will detract from the performance.

-35 oC to 0 oC *
40% water 40% anti-freeze 20% alcohol
For the RU-200 or FC-200 units:
Temperature
Liquid
-20 oC to 30 oC *
50% water 50% anti-freeze.
* Warning: Above 0oC alcohol may evaporate from the liquid
giving a health and safety hazard and also deteriorating the mix.
Check with health and safety procedures before using above 0oC.
Above 30oC anti-freeze may give off dangerous fumes. Again
check with health and safety procedures before using above 30oC.
There is no liquid which will cover the full range of working
temperatures. The units are designed to work up to 40oC with
occasional peaks to 100oC, see Precautionary Measures in the
Operation section. However with the coil removed and a TU-20D
or a TU-20C in the bath, the baths themselves are quite capable of
going to 250oC.
3 Hoses should be as short as possible and secured with clips.
4 The whole system should be insulated as much as possible.
5 DIP COOLERS
Set up a bath and thermoregulator as described in the operating
book for the thermoregulator.
The coil support supplied with the Dip Cooler mounted on a
stainless steel plate is used in place of the small cover on the
bridge piece of a Techne Bath. Slip the coil support onto the coil
and allow it to rest against the end of the flexible. Tighten the
knurled black screw on the coil support to prevent the coil moving
in the coil support, do not overtighten. Remove the blank cover on
the bridge piece and lower the coil through the hole in the bridge.
Fix the support securely to the bridge with the two knurled screws
previously removed.

6 FLOW COOLERS
Connect the Flow Cooler to a system using 16 mm bore hose
which is capable of withstanding both the temperature of
operation and the liquid being used. 12 mm bore hose may be
used if the hose is soft such as silicone rubber. Ensure the flow
is in through the INLET pipe and out through the OUTLET as
cooling power will be lost if the flow is reversed.
OUTLET
INLET
If the system is of a small bore or the viscosity of the liquid
prevents the flow being maintained, a by-pass should be
incorporated in the system.

Carrying a Dip Cooler
A support clip is provided which should be fixed to the side of the
unit if it is required to move the unit frequently. It not only makes it
easier to carry it also protects the flexible hose. The support clip
consists of a block and a long screw. To fit it to the Cooler, remove
the screw in the cover at the rear on the opposite corner to the coil,
the long screw goes through the block and replaces the screw just
removed. There is a lip on the block which should fit over the edge
of the cover to give the support stability. The coil is then clipped into
the support for ease of carrying.

Cleaning your unit
Before cleaning your unit, disconnect from the power supply and
allow to cool to ambient temperature.
You can clean the case of the refrigerated unit with a cloth dipped in
water or ethanol (methanol or formaldehyde can also be used). No
part of the case or cover should be immersed in the solvents.
Do not use acetone or abrasive cleaners.
Packing
When you receive your unit, make sure you keep the original
packing in case you ever need to return it for service or repair.
The unit must be transported in the original packing to avoid
damage. Techne accepts no responsibility for damage incurred
unless the unit is correctly packed and transported in this way.

OPERATION
Precautionary Measures
1 Do not operate any of the fridge units without liquid in the circuit.
Ensure that the evaporation coil on the Dip Cooler is covered.
Ensure that the heat exchanger in the Flow Cooler is full.
2 Freezing may occur if there is insufficient circulation or the
incorrect liquid is used. While this will not harm the unit some
time may pass before the unit can be used again. For this reason
there should always be circulation in or around the coil either in
the bath or in the heat exchanger. This is particularly the case for
the heat exchanger as the passages are small and it cannot be
seen if the unit is frozen. Loss of performance will occur if
freezing takes place. Flow through the heat exchanger should be
at least 10 litres/min at 20oC.
3 To avoid thermal shock do not insert a cold cooling coil into, or fill
a cold heat exchanger with, liquids above 40oC.
4 Although the practice is not recommended fridge units may
occasionally be subjected to temperatures up to 100oC. This is
provided that they are only being used thus intermittently, for
example for cooling down to temperatures below 40oC.
5 IN NO CIRCUMSTANCES MAY A REFRIGERATED UNIT BE
SUBJECTED TO BATH/LIQUID TEMPERATURES ABOVE
100oC.
6 For continuous use above 40oC either remove the coil from the
bath (Dip Coolers) or reconnect the circuit without the heat
exchanger in it (Flow Coolers).
Operating your unit
1 Switch on the thermoregulator or circulator as instructed in the
appropriate book so that good circulation is established.
2 Switch the fridge unit on by pressing the power switch. The
switch and the indicator on the front will light up. The fan and the
compressor will start. It will take a little while for cooling to begin.
3 Remember that as the Fridge units will only extract heat, a
controller, such as a TE-10 or TU-20 thermoregulator or C-85
circulator, will need to be incorporated in the system.
Temperatures are set on and controlled by the temperature
controller, see the appropriate book.

Daily Maintenance
As mentioned earlier, it is imperative that the air flow is not impeded
in any way. It is important that the grilles are kept clean and clear at
all times. Even dust and fluff can impair the performance, therefore
the units must be used in a clean environment or they should be
regularly cleaned.
Fault Finding
1 Check that the airways have not been restricted either by
something placed in front of them or through build up of dust and
fluff on the grilles, etc.
2 Loss of performance is most often caused by deterioration of the
working liquid. As a first check always mix up a new batch of
liquid and re-test the unit. NEVER top up the mix with water
always use a quantity of the proper mix.
3 The next most common cause of poor performance is that the
liquid is not being circulated over the coil or through the heat
exchanger properly. First check that the pump unit is not blocked
either by foreign matter or by balls from a ball blanket or in any
other way. Also check that the pipe system, if you are using the
fridge unit for an external system, is not kinked or restricted in
any way.
4 If the liquid or the circulation is not the cause of the poor
performance then there may be a number of other causes.
5 Check that the internal fan is running by feeling if there is air
blowing when the unit is on. If not then the unit needs servicing
as below.
6 Check that the compressor is running by listening for it to start
and stop as the unit gets to its lowest temperature. If not then the
unit needs servicing as below.
7 Last of all the unit may have lost gas and needs servicing as
below
8 For detailed repair instructions of the thermoregulator refer to the
appropriate model instructions.
NOTE: Before any work is undertaken on the thermoregulator it
MUST be removed from the bath.
