5.4. Bath fluids
Caution:
Carefully read the safety data sheet of the bath liquid used, particularly with regard to the fire
point!
If a bath fluid with a fire point of 65 °C is used, only supervised operation is possible.
Recommended bath fluids

Caution:
Fire or other dangers when using bath fluids that are not recommended:
Please contact JULABO before using other than recommended bath liquids.
JULABO assumes no liability for damage caused by the selection of an unsuitable bath fluid.
Unsuitable bath fluids are fluids which, e.g.,
are highly viscous
(much higher than 30 mm
2
/s at the respective working temperature)
have a low viscosity and have creep characteristics
have corrosive characteristics or
tend to crack.
No liability for use of other bath fluids!
ATTENTION: The maximum permissible viscosity is 30 mm
2
/s.
Caution:
The use of water in purified or unpurified form is not allowed.
Examples: Tap water, distilled water, water-glycol mixture, CaCl

-brine
Important notice
Tempering liquid
The circulator can only be operated in closed tempering circuits. The contact of the
tempering liquid with atmospherical oxygen only takes place in the not-flowed cooling
zone. A safety equipment with definitely adjusted temperature value (170°C 5 °C)
works independantly from the control circuit and supervises the temperature in the
cooling zone. From 160 °C on the warning >hot cooling zone< is shown in line 4 of
the DIALOG-DISPLAY (LCD).
If the temperature of the liquid reaches the safety temperature (170 °C), a complete
shutdown of the controlled heating device is effected. So it becomes possible to use
tempering liquids with a flashpoint from 190°C on.
From a working temperature of 200°C on always work with counter-cooling.
