防冻液and inhibitors
Biocides prevent corrosion that is caused by slime-forming,
corrosive or iron-depositing bacteria. These can occur in closed
cooling circuits with low water hardness and in open cooling
circuits. Biocides must always be selected according to the
relevant bacterial risks. Compatibility with inhibitors or antifreeze
used with them must be checked on a case-by-case basis.
推荐服务
The manufacturer of the antifreeze/inhibitor should analyze
冷却剂每年至少一次。浓度和
boundary conditions of the antifreeze/inhibitor should be
checked. It may be necessary to correct the concentration
