Non-compliance with the compatibility between the thermal fluid and your temperature control
unit
MATERIAL DAMAGE
Observe the classification of your temperature control unit according to DIN 12876.
Ensure the following materials are resistant with respect to the thermal fluid: Stainless steel
1.4301/ 1.4401 (V2A), copper, nickel, FKM, red bronze/brass, silver solder and plastic.
The maximum viscosity of the thermal fluid must not exceed 50 mm²/s at the lowest working
temperature!
The maximum density of the thermal fluid may not exceed 1 kg/dm³!
Mixing different thermofluids in a thermal fluid circuit
PROPERTY DAMAGE
Do
not
mix different types of thermofluid (such as mineral oil, silicone oil, synthetic oil, water,
etc.) in a thermofluid circuit.
The thermal fluid circuit
must
be rinsed when changing from one type of thermal fluid to an-
other. No residues of the previous type of thermal fluid may remain in the thermal fluid circuit.

Thermal fluid composition
The mixture’s temperature must be 10 K below the permissible min. tem-
perature. For the permissible temperature range, refer to the datasheet
from page 73 in Section
.
For thermal fluids we recommend the media listed in the Huber catalog. The name of a thermal
fluid is derived from its working temperature range and its viscosity at 25 °C.

To be noted when planning the test
Also observe page 13 in section
.
The focus is on your application. Bear in mind that system performance is influenced by heat trans-
fer, temperature, thermal fluid viscosity, volume flow, and flow speed.
▪
Make sure that the electrical connection is adequately dimensioned.
▪
The installation location of the temperature control unit should be selected so as to ensure ade-
quate fresh air, even with water-cooled chillers.
▪
Select the thermal fluid to be used in such a way that it not only permits the minimum and maxi-
mum working temperature but is also suitable with regard to fire point, boiling point, and viscosi-
ty. In addition, the thermal fluid must be compatible with all the materials in your system.
▪
Basically, you should only use the thermal fluid recommended by the manufacturer and only
within the usable temperature and pressure range.
▪
The application should be roughly at the same height of or below the temperature control unit if
the thermoregulation is close to the boiling temperature of the thermal fluid.
