Fungi and yeasts prefer to grow in the air, in areas with high humidity – different from bacteria, which prefer to grow inliquids.
In cooling lubricant circuits this effect is well known, stalactites of fungi are hanging from covers of tanks and ducts.Nests of fungi and yeasts can form in damp places which are splashed occasionally. These in turn form the breeding ground for bacteria which then multiply within the liquid coolants.
To combat acute fungal infestation as well as to prevent fungal growth in cooling lubricant systems, the fungicide o-phenylphenol (OPP), which is globally approved for the application in metal working fluids has proven very effective.
Even without the use of formaldehyde donors or CMIT/MIT a reliable protection against all kinds of microorganisms can be achieved by using more favourable bactericides like MIT or BIT/MIT in combination with OPP in coolant emulsions. Coolant emulsions which are highly alkaline with amines can
also be protected well with OPP and therefore may not need
the addition of bactericides</a>
