Cooling towers are essentially large air scrubbers. If your facility is located near a dusty road, a construction site, or an agricultural area, airborne particulates can enter the tower, dissolving and artificially spiking conductivity. This often necessitates a higher bleed rate than calculations predict.

Cooling Water Conductivity: A Comprehensive Guide Cooling water conductivity is a critical measurement used to monitor the concentration of dissolved minerals and salts in industrial and electronic cooling systems. It directly reflects the water's ability to conduct an electric current, which increases as the concentration of dissolved ions—such as calcium, magnesium, and chloride—rises.

This post details what conductivity measures, why it matters, and how to control it.
