Interconnecting cooling circuits
NOTICE
Leaks associated with rigid connections
Rigid connections between the cooling circuits can lead to problems with leaks!
• Use flexible connections (hoses) when interconnecting cooling circuits.
You can connect stator segment cooling circuits in parallel to simplify connection systems
and piping. In this case, you must carefully take into consideration the temperature and
pressure differences between the intake and return.
Note
Connect the stator segment cooling ducts in parallel. This ensures that each stator segment
is supplied with coolant with the same intake temperature.

Materials used in the cooling circuits of stator segments
The stator segment cooling circuits contain the following materials (without the connecting
component materials):
● 1.4301/1.4305 /1.4310
● FKM 70
● CW024A according to DIN EN 1057
● Bare Ms58
● 70G30HSLR BK 099
