Unit Description

5.2

Safety class

according to

DIN

12879

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

taken!
