Methanol
or
Ethanol
Those liquids are usually only used at lower temperatures.
Their flash point is at about
10°C.
Therefore, they cannot be
used in accordance with the standards
EN
61010
or
DIN
12879.
Thermo Haake offers a range of heat transfer liquids for
these temperature control applications.
Synth
...
:
Synthetic thermal liquid with a medium life span
(some months) and little smell annoyance.
SIL
...
:
Silicone oil with a very long life span
(>
1
year)
and negligible smell.
Please use the table on the next page or get in contact with
us if you should have any questions. We are
glad
to advise
you and can help you to choose
a
heat transfer liquid suitable
for your application.
Thermo Haake heat transfer
liquids
are supplied
with
an
EC
Safety Data Sheet.
Thermo Haake takes no responsibility for damages
caused by the selection of an unsuitable bath liquid.
Unsuitable bath liquids are liquids which
e.g.
are very highly viscous (much higher than
30
mPa-s at
the respective working temperature)
have corrosive characteristics or
tend to cracking
It
is absolutely mandatory that the overtemperature cut-
off point is set lower than the fire point for the heat trans-
fer liquid selected
(see
chapter
14.).
The highest working temperature as defined by the
EN
61 01 0
(IEC
1010)
must be limited to
25°C
below
the fire
point of the bath liquid.
Please ensure when selecting other heat transfer liquid
than ours that no toxic gases can be generated and bear
in mind that inflammable gases can build up over the liq-
uid during usage.
At bath temperatures of over
200°C the
usage
of
a
heat
take-off
is
recommended.
