4.4 LAUDA heat transfer liquids
DANGER!
Use of unsuitable heat transfer liquid
Fire

Select a heat transfer liquid with a temperature range suit-
able for the application.
CAUTION!
Use of unsuitable heat transfer liquid
Equipment damage due to freezing

Select a heat transfer liquid with a temperature range suit-
able for the application.
For general consideration:

The heat transfer liquid used must have an electrical conduc-
tivity greater than 1 µS/cm.

Silicone oils and mineral oils are not suitable for through-flow
control.

Observe the safety data sheet for the LAUDA heat transfer
liquid being used. If required, you can download corresponding
safety data sheets from our homepage.

In the Download center, chose the [Safety data sheet] option
in the [Document type] drop-down list.
A list of safety data sheets in PDF format in different lan-
guages is displayed.
Tap the relevant safety data sheet.
The download starts and the PDF file is downloaded.

Never use contaminated heat transfer liquid. Contamination in
the pump housing can cause the pump to seize and the device
to shut down.
For attention when using Kryo 30:

If the heat transfer liquid reaches the lower limit of the tem-
perature range, the temperature control properties can be
expected to deteriorate as a result of the increase in viscosity.
Therefore, only fully utilize this temperature range when abso-
lutely necessary.

The water content decreases during longer periods of operation
at higher temperatures and the mixture becomes combustible
(flash point 119°C). Check the mixing ratio using a hydrometer.
