1 Intended use

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.

6.2 Bath fluids

it - Wasser @ 0\mo d_140 921845 5850_18 .doc x @ 6972 @ 3 @ 1

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.

16



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.

Water bath protection products

The water bath protection product "Aqua-Stabil" is recommended to
combat algae, bacteria and fungus formation.

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.

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 CO

2

equivalent of the system. This is
calculated from the refrigerant fill volume and type of refrigerant.
The CO

2

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.
