(3) Water cooling Circuits Precautions
Please be noted as below.
l
The cooling circuit material must be selected to avoid corrosion.
l
In order to avoid blockage caused by oxidation, the cooling circuit are not recommended to be made of
aluminum, zinc, mild steel or cast iron.
l
The cooling circuit are recommended to be made of stainless steel, copper, copper alloy and opaque
plastic pipe, etc.
l
It's better to recommend an opaque pipeline system to avoid bacteria or moss in the pipeline.
l
The temperature of cooling liquid must be above dew point to avoid condensate on the inner assembly.
The high purity nitrogen is needed to protect the laser system before cooling liquid.
l
Before shipment or storage, drain off the contaminated cooling liquid.
2.7.2 Cooling Water Specification
To endure trouble-free operation of the laser and to prevent corrosion in the cooling circuit, the following
requirements must be complied with:
(1)
Quality of the cooling water
Use only de-mineralized, de-ionized or distilled water with an anti-corrosion addictive. Ensure that the
following limits on the water quality are met:
Conductivity
< 1000 μS/cm
Total Hardness
< 10 ppm
pH value of the water
7 – 8.5
Bacterial Level
<1000 cfu/ml
