Unit Description
5.2
Safety class
2
according to
DIN
12879
A
variably adjustable excess temperature protection and in-
dependent low liquid level protection which is preset to the
lowest level allow the usage of different heat transfer liquids.
If a safety element is triggered..
.
the cause for the fault is displayed,
the
safety-relevant components
(heating element,
motor and compressor) are switched off immediately
i.e. the safety circuit transfers the unit to a stable, safe
condition,
the temperature of the heat transfer liquid gradually
adjusts to ambient temperature.
5.3
Applications
As open-bath circulator:
For temperature controlling samples within the circula-
tor's own bath.
As heating circulator:
For temperature controlling closed temperature control
circuits such reactors, heat exchangers or similar ob-
jects.
Temperature controlling of open vessels using the
built-in combined pressure and suction pump.
5.4
Temperature ranges
Working temperature range:
The temperature range of the circulator without addi-
tional heating or cooling sources.
Operating temperature range:
The temperature range of the circulator which can be
reached if additional heating or cooling sources are
used.
Tap water can be used as a cooling source. In this case
the minimum working temperature possible is approx.
3°C
above that of the tap water temperature.
!
High operating temperatures mean the unit sur-
faces heat up. Protective measures must
be
taken!
