7.4.1 Water quality
In order to ensure long trouble-free operation the cooling-water must not contain any oils,
greases and suspended solids. Moreover, we recommend compliance with the following
limit values:
Appearance
Clear, free of oils and greases
Suspended matter
< 250 mg/l
Particle size
< 150 μm
Electrical conductivity
< 700 μS/cm
pH value
7.0 to 9.0
Total hardness (total alkaline earths)
< 8 °dH
Aggressive carbon dioxide
None, not detectable
Chloride
< 100 mg/l
Sulfate
< 150 mg/l
Nitrate
≤ 50 mg/l
Iron
< 0.2 mg/l
Manganese
< 0.1 mg/l
Ammonium
< 1.0 mg/l
