Description
Impurities
Mechanical impurities in half-open cooling systems can be counteracted when ap-
propriate water filters are used.
Salt concentration
The salt content can increase through evaporation at half-open systems. Thus the
water is more corrosive. Adding of fresh water and removing of process water
works against.
Algae and myxobacte-
ria
Algae and myxobacteria can arise caused by increased water temperature and
contact with atmospheric oxygen. The algae and myxobacteria clog the filters and
obstruct the water-flow. Biocide containing additives can avoid this. Especially at
longer OFF periods of the cooling circuit preventive maintenance is necessary.
Organic materials
The contamination with organic materials must be kept as small as possible, be-
cause separate slime can be caused by this

Damages at the unit which are caused by clogged, corroded heat sinks or other
