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 anti-freeze used with them must be checked on a case-by-case basis.

Protection against condensation

With liquid-cooled units, warm air can condense on the cold surfaces of heat sinks, pipes and hoses. This condensation depends on the air humidity and the temperature difference between the ambient air and the coolant.

The water which is produced as a result of condensation can cause corrosion as well as electrical damage such as creepage shorts and flashovers. Since SINAMICS units cannot prevent condensation when it is caused by the prevailing climatic conditions, measures must be implemented in the system configuration or in the customer’s installation in order to preclude the risk of condensation. These measures include the following:

  • a fixed coolant temperature that has been adjusted to the expected air humidity or ambient temperature ensures that critical differences between the coolant and ambient air temperatures do not develop or
  • temperature regulation of the coolant as a function of the ambient air temperature

The temperature at which water vapor contained in the air condenses into water is known as the dew point. In order to reliably prevent condensation, the coolant temperature must always be higher than the dew point.

The table below specifies the dew point as a function of room temperature T and relative air humidity ? for an atmospheric pressure of 100 kPa (1 bar). This corresponds to an installation altitude of 0 to approximately 500 m above sea level. Since the dew point drops as the air pressure decreases, the dew point values at higher installation altitudes are lower than the specified table values. It is therefore the safest approach to engineer the coolant temperature according to the table values for an installation altitude of zero.
