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.

• These circulators are operated via the splash-proof keypad. The
microprocessor technology allows the setpoint to be set, displayed
and saved using the temperature display LED.
• The PID temperature control automatically adjusts the heat supply to
the requirements in the bath.
• ATC - Absolute Temperature Calibration (1-point calibration)
• The pump function can be switched from internal to external
circulation by a simple switchover button.
• Safety equipment to IEC 61010-2-010:
- The excessive temperature protector is a safety device which
is independent of the control circuit whose value is set using
a tool (screwdriver).
- A float switch acts as the low level safety device. If these
safety devices trip, the heater and circulating pump are
completely shut down.
• Interfaces:
- CAN bus to communicate with the refrigeration machine
- USB connector to act as host to update and read data. USB device

Danger of burns and property damage if unsuitable bath
fluid is used.
•Use only 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
homepage at www.julabo.com. Do not exceed the maximum viscosity of
2
/s when you select your product.
50 mm
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?

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.
Second method
Secure barbed fittings to the union nuts. 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.

Page 26
9.3 Tubing
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
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 hoses. 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
•Compare the mains voltage and frequency with the details on the
model plate.
•The device may only be connected to power outlets with a ground
contact (PE – protective earth).
•The mains plug serves as a safe disconnecting device from the
power supply network and must be freely accessible at all times.
• Do not start the device if it has a damaged mains cable.
• Check the mains cable regularly for signs of damage.
• We disclaim all liability for damage caused by incorrect line
Commissioning the circulator with a refrigeration machine
Connect the circulator and refrigeration machine using the mains lead.
Connect them to the voltage supply using the fitted plug on the
refrigeration machine and the mains lead. Connect the CAN jacks on
both devices with the CAN connection cable to transfer data.
What should be observed when operating the JULABO
temperature control unit?
• Unit parts may develop high surface temperatures. A hot surface
means it has a temperature of 140 °F / 60 °C or more.
• Let the device cool down to an uncritical safe temperature.
• Use safety gloves

17.2 Cleaning
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 under normal conditions.
Regular maintenance work is not required.
The bath tank should only be filled with suitable bath fluid. In case 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.
•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 dish washing-up liquid and
a soft cloth to clean the bath.
•In case of heavy soiling, particularly with grease, benzol-free
pure benzene (washing benzene, light benzene) can be used for
cleaning.
Other cleaning products Never use solvents such as: Never use the following:
Alcohol compounds up to 5%
alcohol content*
Washing benzene*
Javel water, bleach*
Petroleum ether*
Ammonium hydroxide*
Soap suds**
Soda water**
Souring agent
Acidic cleaning products
(degreasing)
Washout solvent
Spray cleaners for glass
windows
Scouring cloths
Brushes
