Condensates within the device
The device must not be operated in a condensing atmosphere. The humidity has to be considered in order
to prevent condensates within and outside the device.
The temperature of the cooling water must not be lower than the dew point.
Tab. 8.5:
Dew point Diagram
Example
Air temperature:
Relative humidity:
The cooling water temperature must not fall below 14 °C.
Flow rate
The value for the flow rate should not be below 0.7 l/min per kW laser power.
The following rule of thumb can be used to determine the flow rate - depending on the laser power used:
For each kW of laser power, a flow rate of approx. 1 l/min of cooling water is required.
Example: With a laser power of 7 kW, this corresponds to a flow rate of 7 l/min.
