Coolant specification
4.5.1
General coolant requirements
The coolant must fulfill the following requirements over the long term. The coolant is based on
filtered drinking/municipal water of the quality specified below.
De-ionized water
Specific conductivity
< 30 μS/cm
Evaporation residue
< 20 mg/l
NOTICE
High percentage of chloride in drinking water
According to Directive 98/83/EC, drinking water may contain up to 250 mg/l of chloride. This
value is too high for the heat sinks, which may be destroyed if inhibitors are not added.
Use inhibitors if the drinking water has an excessively high chloride percentage.
To better explain the coolant recommendations in this document, some of the problems that
can be encountered if the recommendations are ignored are listed in the table below.
