Other coolants (not water-based)
If you use other cooling media (e.g. oil, lubricating coolant), then it may be necessary to
reduce the motor power (derating) so that the thermal motor limit is complied with.
(Derating)
Note
Oil-water mixtures with more than 10 % oil require derating.
Determine the values of the coolant from the following table:
Formula symbol Unit
Density ρ kg/m
3
Specific thermal capacitance c
ρ
J/(kg•K)
Thermal conductivity λ W/(K•m)
Kinematic viscosity η m 2 /s
Flow rate V l/min
Third-party cooling jacket Cooling jacket geometry is required
Contact your local Siemens office for the power reduction (derating) resulting from the
values.
Biocide
Closed cooling circuits with soft water are susceptible to microbes.
● If possible, use chlorinated potable water.
Note
Compatibility of coolant additives
Biocides and Antifrogen N must not be mixed.
● If no chlorinated potable water is available, add, for example Antifrogen N or a
biocide, to the potable water.
