6.2 Amount of Cooling Water Required
Warning!
Risk of damage!
The cooling water flow must not be turned off if the maximum
ambient temperature of the detector (see technical data in chapter
13.2) will be exceeded even if the facility is not in operation.
In case of danger of frost the water cooling has to be emptied.
Dirty cooling water may block up the water cooling so that the
detector may get overheated and destroyed. Make sure to use
clean cooling water!
The amount of cooling water required may be taken from the
graph below.
 The X-axis shows the max. achievable ambient temperature.
 The different characteristic curves are valid for the respective
feed temperature of the cooling water.
 The Y-axis shows the min. required water flow.
