5.4. Bath liquids
Caution:
•
Carefully read the safety data sheet of the bath liquid used, particulary with regard to the
fire piont!
•
If a bath fluid with a fire point of
≤
65 °C is used, only supervised operation is possible.
•
The use of water in purified or unpurified form is not allowed.
Examples: Tap water, distilled water, water-glycol mixture, CaCl
2
-brine
Recommended bath fluids:
See website for list of recommended bath fluids.
Contact: see page 6
Caution:
Fire or other dangers when using bath fluids that are not recommended:
Please contact JULABO before using other than recommended bath fluids.
Use only nonacidic and noncorrosive bath fluids.
JULABO assumes no liability for damage caused by the selection of an unsuitable bath
liquid.
Unsuitable bath fluids are fluids which, e.g.,
•
are highly viscous
(much higher than 50 mm
2
x s
-1
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 50 mm
2
/s.
Important notice concerning the recommended bath liquids:
Bath liquids with a range of application above the fire point ?
This temperature system is mainly operated in a
closed external system (loop circuit). The
contact of the bath liquid with atmospheric oxygen only takes place in the internal reservoir,
which is not located directly in the termperature circuit.
A safety device supervises and controls the the temperature in the internal reservoir.
The temperature of the bath liquid is maintained constant at approx. +20°C
The safety device with an adjustable temperature value >RES< works independently
from the control circuit. When actuating this safety device (too much hot fluid streams
into the internal reservoir) the temperature system is switched off all-polo and
permanently.
Adjust the safety temperature >RES< at at least 25 °C below the fire point of the bath
liquid.
