JULABO circulators are laboratory devices which are designed for the
temperature control of certain liquid media in a bath tank or with a
refrigeration unit. The bath fluids recommended by JULABO must be
used as tempering media.

Units with pump connections allow the tempering tasks to be carried out
in an external temperature control system.

JULABO circulators are not designed for the direct temperature control of
foods, semi-luxury foods and tobacco, or pharmaceutical and medical
products.

 Direct temperature control means unprotected contact between the

object and the tempering medium (bath fluid).

 The devices are not suitable for use in potentially explosive

environments.

8.4 Bath fluids

Danger of burns and property damage if unsuitable bath
fluid is used.

 Only use thermal oils which are recommended by JULABO. The

viscosity of the oil is tailored to the pump capacity.

 Refer to the safety data sheet of the bath fluid, particularly its

flash point.

 Set the excess temperature protector correctly.
 Always store bath fluid so that it cannot harm the environment.

There is a selection of recommended bath fluids on the JULABO

. Do not exceed the maximum viscosity of

50 mm2/s when you select your product.

Water as the bath fluid

If you use water as the bath fluid

Recommended water mixture:
70 % soft/decalcified water and 30 % tap water for a temperature
range from 5 °C to 80 °C.

The parts of the bath which come into contact with the bath fluid
may be damaged and cause the failure of the device.

The water quality depends on the local conditions.
 Hard water is not suitable for temperature control tasks due to

its high lime content and will produce lime deposits in the bath.

 Ferrous water can cause corrosion, even on stainless steel.
 Chloric water can cause pitting corrosion.
 Distilled and deionized water is not suitable. Their specific

properties cause corrosion in the bath, even on stainless steel.

 Check the quality of the water you use at regular intervals.
 Evaporation and constant refilling may produce a concentration

of harmful substances in the bath.
You should therefore check the quality of the water in the bath
at regular intervals.

 Replace the water in the bath in full at regular intervals.

Unsuitable bath fluids.

JULABO cannot accept any liability for damage caused by the selection
of an unsuitable bath fluid.

Unsuitable products include bath fluids which
 are highly viscous (much higher than recommended at the

relevant working temperature).

 tend to crack.
 have a toxic, caustic or corrosive effect.

Properties of indirectly temperature-controlled fluids and
substances

The intended use of the units includes the indirect temperature control
of fluids.

We do not know which substances these are.
Many substances are:

• inflammable, flammable or explosive

• harmful

• polluting

In other words: dangerous

The user bears sole responsibility for handling these substances!
Use personal protective equipment!

The following questions should help to identify possible dangers and
minimize risk.

 Are hazardous vapors or gases produced when heated?

Does operation of the bath has to be conducted in a fume hood?

 What should you do if a dangerous substance has been spilled on

or in the device?
Obtain information on the substance before starting work and
define a decontamination method.

 Are all hoses and electrical cables securely connected and routed?

Keywords: Sharp edges, hot surfaces during operation, moving
machine parts, etc.

8.5 Temperature control for external connected systems

Danger from the incorrect use of external connected
systems.

Unsuitable materials may cause the failure of the system.

Check the externally connected systems for the
following:

 Compression strength.
 Corrosion resistance.
 Check the materials used for parts in contact with the medium.

The circulator is designed for the temperature control of external
connected systems (temperature control system).

Connect an external system

Remove the union nuts and sealing plates from the pump connectors.
The tube connectors can be used for tubing with M16x1 (internal)

connections in this state.
Tighten the connections with a maximum torque of 3 Nm, holding the

nuts (a.f. 17 mm) as you do so.

Second method

Secure barbed fittings to the union nuts. Tighten the connections with
a maximum torque of 3 Nm, holding the nuts (a.f. 17 mm) as you do
so.

Connect tubing and secure them with tube clamps to prevent them
sliding off.

Connect the tubing for the supply and return to the pump connectors
and the external consumer and secure them with tube clamps.

Switch the pump function to external circulation.

Danger of injury from defective tubing.

The bath fluid tubing is a potential source of danger at high working
temperatures. Large volumes of hot bath fluids can be pumped out of a
damaged tubing in a short period of time.

Possible consequences:

• Skin burns

• Breathing problems due to the hot atmosphere

Danger from unsealed pump connections.

• If the pump connections are not sealed, bath fluid may be pumped

out without any control.

• Set the lever on the pump to internal circulation.

• Unused pump connections must always be sealed with sealing

screws.

Danger from the incorrect use of tubing.

• The tubing must be suitable for the pressure and temperature range

which results from operation and for the bath fluid (for example
silicon oil must not be used with silicon tubings).

• Secure the tubing connections to prevent them sliding off. Use tube

clamps.

• Do not kink the tubing. This will reduce throughput and may cause

the maximum pressure in the system to be exceeded (glass
reactor). The tube length should therefore be kept at a reasonable
level.

• Prepare a maintenance plan.

Check tubing at regular intervals, at least once per year, for signs
of material fatigue (for example cracking)
The tubing must be replaced at regular intervals if they are in
constant use.

We recommend that you select suitable tubing on the JULABO
homepage.

ump settings

Basic dangers.

The volume of oil used as bath fluid changes with the temperature.
Starting from the volume when the bath is filled (room temperature) it
may increase or decrease during operation.

The bath temperature rises - hot bath fluid can overflow.
The bath temperature falls - the low level alarm will stop the tempering
process.

Monitor the level until it reaches working temperature.

Filling process

 Ensure that the drain valve is closed. Turn the knurled screw.
 Carefully insert bath fluid - never allow bath fluid to get inside the

circulator.

 Do not exceed the maximum bath capacity (see Technical Data).
 1 - The bath temperature rises - hot bath fluid can overflow.
 2 - The bath temperature falls - the low level alarm will stop the

tempering process.

 Monitor the level until it reaches working temperature.

To meet all the requirements for internal and/or external temperature

ontrol tasks, the direction of the pump flow is continuously

c
adjustable.

For this purpose the lever below the head of the circulator can be
adjusted from:

1.) Max. internal pump flow to...

2.) Max. external pump flow.

Risk of burns due to hot bath fluid

When adjusting the pump flow, make sure that no bath fluid is spilled
from the bath opening due to circulation. For internal temperature
control (external pump connections closed), the adjusting lever is to
be set first to reduced internal circulation (2) before the circulator is

The target temperature is the setpoint temperature,
which is reached after completing a step. Based on
the time and temperature difference in a step, the
programmer calculates a temperature ramp (1).

Caution:
If the time specified is too short, the actual
temperature cannot reach the setpoint temperature.
For this case, the programmer can be used to edit a
profile.

If the time for a step is defined as 00:00:00, the
setpoint temperature “jumps” (2) to the target
temperature.
Only after the specified temperature is reached
(±0.2 °C), the profile is continued with the next step.

Eight profiles with up to 60 steps each can be stored.

The Standard or Gradient settings can be mixed
in a profile.

Setpoint = green

Emptying the bath tank

16 Emptying the bath tank

Danger of scalds from hot bath fluid or hot drain tap.

Please note the following when draining the bath fluid:

• Hot bath fluid:

Do not drain the bath fluid when it is hot.

• Environmental Hazard:

Refer to all regulations for disposing of bath fluids.

Emptying

 Switch off the unit and pull the plug or disconnect the connection

to the power supply on all poles.
For baths without a drain tap, remove the circulator from the bath
tank.

 Small bath tanks do not have a drain tap and can be carried for

drainging. The temperature of the bath fluid should not exceed
50 °C.

Enclosed baths and refrigeration machines

 Connect a suitable hose to the drain port ( 12 mm external).
 Route the hose to a vessel or drain.
 Open the drain valve with the knurled screw.

 To reduce the weight, the bath can be partly emptied using a hose

p

ump (transfer pump).

 Do not empty the bath in temperatures of ≤ 0°C since the drain

tap may freeze.

Information about the used refrigerants

The Regulation (EU) No. 517/2014 on fluorinated greenhouse
gases applies to all systems which contain fluorinated refrigerants and

replaces (EC) 842/2006.
The aim of the Regulation is to protect the environment by reducing

emissions of fluorinated greenhouse gases.
Among other things it regulates the emission limits, use and recovery of

these substances. It also contains requirements for operators of systems
which require / contain these substances to function.

Materials of parts in contact with the bath fluid

Under Regulation 517/2014, the operator of a system of this nature has
the following duties:

 The operator must ensure that the equipment is checked at regular

intervals for leaks.

 These intervals depend on the CO2 equivalent of the system. This is

calculated from the refrigerant fill volume and type of refrigerant.
The CO2 equivalent of your system is shown on the model plate.

 The operator undertakes to have maintenance, repair, service,

recovery and recycling work carried out by certified personnel who
have been authorized by JULABO.

 All such work must be documented. The operator must keep records

and archive them for at least five years. The records must be
submitted to the relevant authority on request.

Refer to the text of the Regulation for further information.

Maintenance, cleaning, storage

20 Maintenance, cleaning, storage

Danger of injury during maintenance, repair and transport
Danger from mains voltage.

• Have all service and repair work carried out by authorized

specialists only.

• Switch off the unit and pull the plug,

- before starting any cleaning work,

- before carrying out any service or repair work or

- before moving the unit.

• Empty the unit completely before moving it.

• Transport the unit carefully.

20.1 Maintain the refrigeration capacity.

The device is designed for continuous operation in normal conditions. No
regular maintenance work is required.

The condenser on the front should be cleaned from time to time to
maintain the full refrigeration capacity.

 1. Switch off the device.
 2. Pull the plug.
 3. Let the unit cool down to room temperature.
 4. Remove the ventilation grille.
 5. Vacuum the dirt on the condenser.

20.2 C

88

leaning

Use low surface tension water (for example soap suds) to clean the bath
and the functional parts of the circulator which are immersed in it. Clean
the exterior device with a cloth and low surface tension water.

The circulator is designed for continuous use in normal conditions. No
regular maintenance work is required.

The bath tank should only be filled with suitable bath fluid. In the event
of contamination, the bath fluid must be replaced from time to time.

Cleaning open bath tanks

• Leaking bath tanks due to unsuitable cleaning products.

• These bath tanks are not resistant to solvents and pure alcohol.

Incorrect cleaning products will make the surface of the bath go
cloudy and will dissolve the adhesive. Plastic baths will
therefore start to leak.

Maintenance, cleaning, storage

• Clean bath tanks with wet products - never rub them dry. The

cloths or sponges you use should not be contaminated (with
scouring particles or dust).

• A good, essentially smear-free cleaning effect can be achieved

using a microfiber cloth moistened with water.

• Use warm water with a few drops of washing-up liquid and a

soft cloth to clean the bath.

• If it has heavier soiling, particularly if it is greasy, benzol-free

pure benzene (washing benzene, light benzene) can be used for
cleaning.

20.3 S

torage

Units which are not to be reused must be stored in a dry, place,
protected from dust and frost, after cleaning. The system components
must be fully emptied and carefully dried, for example using compressed
air. Seal the connectors.
