Biocide
Closed cooling circuits with soft water are susceptible to microbes.
•
If possible, use chlorinated potable water.
Note
Compatibility of coolant additives
Biocides and Antifrogen N must not be mixed.
• If no chlorinated potable water is available, add, for example Antifrogen N or a biocide, to
the potable water.
Antifrogen N acts like a biocide for a minimum concentration > 20%.
•
Conduct a water analysis at least annually to determine the type and concentration of
microbes.
The following microbes can occur in practice:
– Bacteria that cause the formation of slime
– Corrosive bacteria
– Bacteria that cause deposits of iron
•
Add a biocide that counters the determined microbes to the cooling water.
The manufacturer's recommendations must be followed in regard to the dosage and
compatibility with any inhibitor used.
