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.
