Table 11-5
These units and the air-cooled converters are identically constructed.
Instead of the heat sink for air, an air/water cooler has been installed.
All the technical data not listed in Table 11-5 for a particular unit are the
same as those of the air-cooled converter. The first 12 positions of the
Order No. are identical. The supplement "-1AA1" indicates water
cooling.
*)
The cooling water requirement applies for the unit rating of the converter and 100%
utilization of the additional heat dissipation obtained from a water temperature rise
intake/return of ∆T = 5 K.
