Cooling Water Conductivity Jun 2026

To understand conductivity, you must understand Cycles of Concentration (COC). As water evaporates in a cooling tower, it leaves behind dissolved solids. The remaining water becomes more concentrated.

Automatic Temperature Compensation (ATC) to get accurate data. Chemical Interference: Some water treatments (like salt-based softeners) increase conductivity without necessarily increasing scale risk. You have to balance the "number" with the actual chemistry. Summary for Maintenance Calibrate your handheld and inline meters monthly. Monitor CoC rather than just the raw number to understand water efficiency. Inspect Probes for biofilm or scale every time you do a water test. Would you like to dive into the specific cooling water conductivity

Pure water is a poor conductor; however, when substances dissolve in it, they break into positively and negatively charged ions called electrolytes. These ions allow electricity to flow through the water. Therefore, a higher conductivity reading indicates a greater mineral content or total dissolved solids (TDS) in the system. Why It Matters: Scaling, Corrosion, and Safety To understand conductivity, you must understand Cycles of

If you only measure one thing in your cooling water system, make it conductivity. It protects your assets, saves water, and lowers your energy bill. Summary for Maintenance Calibrate your handheld and inline

Cooling water conductivity is a critical parameter in industrial cooling systems, as it directly impacts the efficiency, reliability, and longevity of the equipment. Conductivity refers to the ability of water to conduct electricity, which is influenced by the presence of dissolved ions, such as salts, acids, and bases. In cooling systems, water is used as a coolant to absorb heat from equipment, and its conductivity plays a crucial role in preventing corrosion, scaling, and biological growth.

Most industrial systems aim for 3 to 6 cycles of concentration. If you are running at 2 cycles, you are essentially dumping water down the drain. Increasing from 2 to 4 cycles can reduce makeup water consumption by approximately 33% .
