Assembly of Fluid-Cooled Converter, Size Classes C, D and E
The fluid-cooled devices of size classes C, D and E consist of the device
and a copper plate with a brazed-on copper pipe. This is connected to the
quick-release couplings by a kink-proof hose. The connecting couplings
are integrated in the device. Take the following into account during
assembly:
•
Assembly must be carried out perpendicular to a level construction
area.
•
The fastening screws are shown in the drilling templates of the
dimension drawings.
•
The devices are supplied with quick-release couplings (with lock) Di =
3/8“. However, it is possible to modify the connection cross-section to
1/2“ or 3/4“.
Note: Your distributor can provide you with further information
regarding coolant hoses, hose nozzles, couplings, angular
connections, etc.
Technical Data of Coolant Circulation System, Size Classes C, D and E
Maintain the following to avoid exceeding the highest permitted
temperature in the devices.
•
The nominal diameter of the cooling system is D = 10 mm
•
The maximum system pressure is <3 bar
•
The fluid intake temperature and the dynamic pressure depend on the
volume flow. They can be determined using the diagrams.

The coolant comprises tap water and antifreeze, type Antifrogen N
(Clariant). It is mixed in the ratio 1 : 1. This guarantees frost protection
down to –30 °C.
