Requirements for cooling water
To avoid destruction of the aluminium housing by pitting, the cooling water must meet the
requirements listed in the following table.
NOTE
Pitting in aluminium cooling channels
C1 -05 0
Avoid copper in the cooling circuit. Copper causes pitting in the aluminium cooling channels
unless suitable additives are used. Damage caused by pitting is excluded from the warranty.
The mechanical type „S“ is made of stainless steel. Hence there is no pitting even with copper
parts in the cooling circuit.
