Table 2-7 shows the specifications related to the cooling agent and its circulation. Also see
Table 1-4, Technical Information on Page 1-9.
Table 2-7: Information About Cooling Agent and Its Circulation
A = 100% water; B = Water/Glycol mixture 80:20; C = Water/Glycol mixture (60:40)
Definitions: Min. liquid flow = Minimum flow rate to ensure of total venting of the cooling
element
Nom. liquid flow = Flow rate while running the drive at I
th
Max. liquid flow = If flow rate exceeds max. liquid flow, risk of cooling element
erosion increases
Note: Unless minimum liquid flow rate is ensured, air pockets may develop in the cooling
elements.
