2.10.2 Cooling Water Quality
Do not use the cooling water as drinking water.
If a leak occurs, oil can contaminate the cooling water.
It is imperative that measures for cooling water treatment and filtration are carried out.
The addresses of companies specialising in cooling water analysis and the supply of suit-
able equipment for its treatment can be obtained from KAESER.
To avoid operational breakdowns caused by a corroded or clogged cooler, the cooling
water must meet the following requirements:
pH value
7.5 to 9
Hardness [ dH] 4,0---8,5
Chloride (Cl) [mg/l] < 150
Free chlorine gas (Cl
2
) [mg/l] < 1
Sulphate (SO
