Clean water that is free of dirt and suspended matter must be used as a coolant.
9.7 Min. coolant temperature against ambient temperature and humidity
Figure 12: Determination of the coolant temperature
The allowed coolant temperature depends on relative humidity and ambient temperature. For example
with an ambient temperature of 25 °C and a relative humidity of 65 % the minimum coolant temperature is
25% rel. humidity
35% rel. humidity
45% rel. humidity
55% rel. humidity
65% rel. humidity
75% rel. humidity
