Thermal fluids
We recommend the thermal fluids shown in our catalogue. The name of a thermal fluid
is derived from the working temperature range and the viscosity at 25 °C.
Examples of thermal fluids in our catalogue:
M40.165.10:
Lower working limit -40 °C
Upper working limit 165 °C
Viscosity at 25 °C: 10 mm

The data sheet for the thermal fluid used is of utmost importance, and must be read
before use. This data sheet should be followed.
Please note the classification of your machine according to DIN 12876
The chosen thermal fluid must be compatible with stainless steel 1.4301 (V2A)
and FKM!
The maximum viscosity of the thermal fluid may not exceed 50 mm²/s at the
lowest temperature reached!
The maximum density of the thermal fluid may not exceed 1kg / dm³
Please note
:
For our units we recommend covering with inert gas. Therefore we offer the
sealing set listed in our Huber-Catalogue, valid for unistats of the 3
rd
generation.
As a thermal fluid for chillers a water-glycol mixture
has to
be used (it is
recommended to use a mixture that permits a temperature down to -25 °C)
