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.
Please note:
n If the heat transfer liquid reaches the lower limit of the temperature
range, the temperature control properties can be expected to deterio-
rate as a result of the increase in viscosity. Therefore, only fully utilize
this temperature range when absolutely necessary.
n Never use contaminated heat transfer liquid. Contamination in the
pump housing can cause the pump to seize and the device to shut down.
n Observe the safety data sheets for the various heat transfer liquids. If
required, you can download the safety data sheets from our homepage.
Open the LAUDA homepage, tap  Services  Download center.
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 dierent languages is
displayed.
Tap the relevant safety data sheet.

Please note:
n When using Kryo 30:
The water content decreases during longer periods of operation at
higher temperatures and the mixture becomes flammable (flash point
119 °C). Check the mixing ratio using a hydrometer.
n When using Aqua 90:
Evaporation losses occur at higher temperatures.
n When using Ultra 350 and Kryo 65:
EPDM hoses are not suitable for Ultra 350 and Kryo 65.
n When using mineral oils:
EPDM hoses are not suitable for mineral oils.
n When using silicone oils:
Silicone hoses are not suitable for silicone oils.
n The proportion of alkaline earth ions in the water must be between
0.71 mmol/L and 1.42 mmol/L (equivalent of 4.0 and 8.0 °dH). Harder
water leaves limescale deposits in the device.
n The pH value of the water must be between 6.0 and 8.5.
n Distilled, deionized or fully desalinated (FD) water is unsuitable due to its
reactivity. High-purity water and distillates are suitable as a heat transfer
liquid after 0.1 g of soda (Na
2
CO
3
, sodium carbonate) is added for every
liter of water.
n Sea water is unsuitable due to its corrosive properties.
