Rated flow rate = 10 l/min
For other coolant flow rates than the one stated above, please inquire with Baumüller Nürnberg GmbH.
The coolant must meet the following requirements:
pH value
6.5 ... 9.5
Manganese (Mn)
< 0.05 ppm
Conductivity
50 ... 600 µS/cm
Copper (Cu)
< 0.1 ppm
Total water hardness (incl. CaCO
3
)
< 100 ppm
Chlorine (Cl
2
)
< 1 ppm
Suspended matter
< 10 ppm
Chloride (Cl
-
)
< 500 ppm
Particle size
< 100 µm
Sulfate (SO
2-
4
)
< 500 ppm
Ryznar Stability Index (RSI)
5.0 ... 6.0
The corrosion resistance to other substances can be seen in the DECHEMA material tables.
An anti-corrosion agent and a closed cooling circuit are prescribed.
4)
The surface temperature of the water cooler or cold plate must be higher or the same as the device interior temperature
to prevent condensation always.
In case of surface temperatures other than those specified, please inquire with Baumüller Nürnberg GmbH.

Notes relating to cold plate
The cooling version cold plate is a particular efficient cooling alternative. The heat dissipation is done via 2 contact sur-
faces. The mounting platform within the control cabinet or on the machine base is one, the device, to be cooled is
mounted there. High requirements e.g. to surface roughness and evenness for this surface are specified, to ensure an
optimal heat flow. Already a slight damage/pollution of the surface can cause a significant deterioration in heat dissipation
to the mounting plate.
For this reason while handle the units protect the sensitive function surface to avoid damage and pollution.
6)
By means of the thermal resistance of the cooling system and the thermal power loss, which is supplied to the cooling system, the sur-
face temperature can be calculated.
