1.1 General safety notes
A through flow cooler serves for due cooling of heat transfer liquids which are tempered by means of
a bath thermostat and transferred by pumping. This leads to hazards through high temperatures, fire,
and the general hazards through the use of electrical energy.
The user is largely protected through the application of the appropriate standard specifications.
Additional hazards may arise from the type of material being thermostated, e.g. when going above or
below certain temperature levels or through breaking of the container and reaction with the heat
transfer liquid.
It is not possible to cover all possibilities; they remain largely within the responsibility and the
judgement of the user.
