4.1 Determining the necessary cooling
water temperature
ambient temperature in °C
SG-02007
dew point temperature in °C
Dew point diagram Fig. 2-36
1. Measure ambient temperature (in the example: 36 °C).
2. Measure the relative humidity (80 % in the example).
3. Draw a vertical line in the diagram from the measured ambi-
ent temperature upwards until it intersects with the straight
line representing the measured humidity.
4. Draw a horizontal line from the point of intersection to the
dew point temperature.
5. View the dew point temperature (32 °C in the example).
The temperature of the cooling water flowing through the focus-
ing optics must be at least 2° C above the dew point tempera-
ture: In the example, the cooling water temperature should be at
least 34 °C.
Note
When determining the required cooling water temperature, also
observe the laser device requirements. In tropical countries, the
cooling of the focusing optics must be ensured using an exter-
nal cooling unit. TRUMPF also offers solutions for an external
chiller.
