4.5.2.2 Requirements to the Cooling Liquid
In general the quality of normal purified, soft and largely chlorine-free drinking water is adequate. The quality of
the cooling medium will have a long-term effect on the system performance.
CAUTION
Possible damage to the device!
- Due to electrolytic and/or chemical corrosion
- Due to the deposition of fine sludge
- Due to coating with foreign substances and as a result degradation of the heat transfer
- Due to the deposition of foreign bodies on the heat exchanger surfaces
Avoidance:
- Never use deionised water as a cooling liquid.
- Use fine filters to keep back fine sludge particles.
- Meet the following requirements.
