Customer Requirements Pre Install
Drinkable tap water is likely to meet the above requirements, and water meeting the requirements of VDI3803,
Appendix B, Table B3 does.
When designing the water cooling system, the Laser Integrator should consider the following:
• Deionised water is not permitted in the cooling circuit as the generally high levels of dissolved O
2
and CO
2
in
deionised water cause corrosion.
• Due to the cooling circuit of the laser and BDO incorporate copper, nickel plating and stainless steel, aluminium and
plain carbon or low alloy steels should not be used as galvanic corrosion may occur.
• Bacterial growth, scaling and corrosion will cause low flow rates and reduce heat transfer from the laser therefore
pre-treated water and additives for prevention of corrosion, scaling and microbial growth are available commercially,
for example NALCO and Optishield.
NOTE: Additives may reduce the heat capacity of the water. Therefore the flow rate must be increased to compensate.
