Information on the thermal fluids
Non-compliance with the safety data sheet for the thermal fluid to be used
INJURIES
Risk of injury to the eyes, skin, respiratory tract.
The safety data sheet for the thermal fluid to be used must be read prior to use and its con-
tents respected.
Observe the local regulations/work instructions.
Wear your personnel protective equipment (e.g. temperature-resistant safety gloves, safety
goggles, safety footwear).
Danger of slipping through contamination of floor and work area.
Non-compliance with the compatibility between the thermal fluid and your temperature control unit
PROPERTY DAMAGE
Water must not be used as a thermal fluid (risk of freezing and potential destruction of the evaporator).
Observe the rating of your temperature control unit in accordance with DIN 12876.
Ensure the following materials are resistant with respect to the thermofluid: Stainless steel
1.4301/1.4401 (V2A), copper, nickel, Viton (FKM) or Nitrile / NBR / ceramic /
carbon / aloxide, red bronze / brass, nickel-plated brass and silver solder.
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!

When using the optional sealing sets for Unistate in connection with a static inert gas overlay, a
pressure limit of 0.1 bar (g) must be used.
As thermal fluids we recommend the media listed in the Huber catalog. The designation of a ther-
mal fluid is derived from its working temperature range and the viscosity at 25 °C.
We recommend inert gas overlay for your temperature control unit. We therefore offer the sealing
set for Unistate in our accessory range. The temperature control units of the 400 series are already
standardly equipped with the connections for inert gas overlay.
When using Unistats, the thermal fluid is protected from environmental influences. Thus an in-
creased accumulation of moisture or an oxidative degradation of the thermal fluid is prevented.
Using a static overlay with an inert gas, a further significant extension of the useful life of the
thermal fluids can be achieved. This is especially true if you want to work long-term near the oper-
ating temperature limits of the thermal fluids. (hygroscopy, oxidation).
