Overtemperature Protection. This unit is
equipped with Overtemperature Protection
(OTP) circuitry to prevent overheating. The unit
will automatically interrupt power whether
equipment malfunction or operator error causes
the temperature to exceed the maximum
recommended temperature range. The power
can only then be restored by identifying and
correcting the problem, allowing the unit to
return to normal operating temperatures, and
resetting the power to the unit.
Heater Element. The heater element (heating
coil) of the distillation unit, installed in the
heating area within the flask support has to be
inspected at least every 3 months. If any short
circuits of the windings are observed, it is
necessary to use a new heater element. It is
important to do this exchange very carefully. The
windings must not have a short circuit and need
to be adjusted carefully before operation. Do
NOT touch the heater element after a distillation
run. The element could still be extremely hot and
one could experience personal injuries.

a rate between 4 mL/min and 5 mL/min is
requested. Use 4.5 mL/min.
Final Heat Adjust
If last 5 mL of distillation run are not in the time,
correction of heating capacity upwards or
downwards is possible. Heat capacity at
constant heat (5mL before ‘Expected volume‘) is
set to 100%. Correction of ±20% is possible.
Stop At Vol.
The distillation run can be interrupted at selected
volume if the entire volume is not necessary.
Stop At Temp.
The distillation run can be interrupted at a
selected temperature if the entire volume is not
necessary.

dry point, or “Yes“ to wait for FBP.
Solvents off Time
Look at info on dry point on how to set this point.
Solvents off Temp
Look at info on dry point on how to set this point.
Fix-Temps
If a temperature is set, the according volume will
be shown.
Fix Temp 1-5
First 5 fix temperatures are generated in the
distillation analyzer and available after the
distillation run. These temperature points can be
written in print out form.
Fix Temp 6-100
These fix temperatures are stored in a memo
field of the database and are online available.

Final Results
All important values are shown online here. That
means if the IBP was detected, it can be seen
immediately. After a distillation run has finished
(yellow lamp at front panel is off and level
follower is in the standby position), the residue
can be input to calculate the loss and
evaporated volume. “First 5ml“ and “Last 5ml“
will be calculated to check for a standard
distillation run.
Dist.Data
Volume, recovered temp., corrected temp.,
evaporated temp., dist rate and heat capacity
will be printed. Steps can be changed in “Config“
then “Menu“.
Graph
Temperature, heat and rate curves are shown
online during the distillation run. Scale of all 3
curves can be changed by pressing right mouse
button.

Data Base: The Koehler software uses a
standard ACCESS database to store programs
and results. “Program.mdb“ contains all stored
programs and “Result.mdb“ contains all made
distillation runs. It is not allowed to manipulate or
change values in the database by an external
programs because of possible data loss. It is
only allowed to read data out of the data base
for export or a LIMS system. In this case a full
installed version of ACCESS is necessary (not
included). For backup use these files.
5 Safety Features
The Koehler Automatic Distillation Analyzer is
equipped with several safety and protection
features, which are described in the following
sections.
5.1 Flask Heater Compartment and
Auto Fire Extinguisher
The design of the flask heater compartment
makes this instrument one of the safest
automatic distillation units available. The
physical dimensions of the heater compartment
are in compliance with the ASTM suggested
specifications. The side walls are insulated with
asbestos-free heat resistant material and the
door is made of polycarbonate.
The heater compartment has an optical fire
sensor mounted on the back wall. This sensor
continuously monitors the compartment to watch
for flask fires that are usually caused by cracked
or broken boiling flasks. In the event of a fire, the
instrument will automatically turn off power to
the critical components. Because of the fire
potential, it is recommended that the instrument
be operated within visual and audible range of
the operators. The instrument should not be
located under or near ceiling mounted sprinkler
type fire extinguishing heads. The area above
the distillation unit should be fireproof also. From
time to time, especially after a fire, the sensor
must be cleaned and checked (possibly with a
lighter) to determine if the function is ok. The
part wears over time. Therefore it must be
changed in case of malfunction!
