Cooling towers are essential to maintaining thermal efficiency and system reliability in industrial and HVAC applications. When something goes wrong — like unexpected biological growth, corrosion, conductivity drift, pump or fan failures, or system imbalance — your operation is at risk of inefficiency, damage, or even shutdown.
This Cooling Tower Troubleshooting Guide is built to help you quickly identify, diagnose, and resolve the most common issues encountered in field service. Whether you're on your first solo service call or a seasoned technician facing a new variable, this guide provides practical support to get you back on track.
Tried-and-true step-by-step workflows based on real-world field service experience. Clear steps, no fluff.
Understand the interaction between chemical treatment, mechanical design, and automated controls — and how small imbalances in one area can create issues in another.
From foaming and scaling to drift losses and low delta T, we break down the warning signs and how to interpret them.
What to look for during routine inspections, and how to document and communicate issues clearly with your team or customer.
This guide was developed with water treatment professionals, mechanical contractors, facility engineers, and field service techs in mind. If you work on or around open recirculating cooling systems, this is your toolbox companion.
