Chemical Treatment

Chemical treatment is how you keep a cooling tower stable over time. The right program reduces scale, corrosion, and biological growth, which protects heat transfer performance and helps avoid unplanned shutdowns.

As water evaporates, dissolved minerals concentrate in the system and operating conditions become less stable. If blowdown control and chemical control aren’t managed properly, scale, corrosion, and biological fouling will reduce heat rejection and efficiency.

When Should you get Chemical Treatment for your Cooling Tower?

When you’re seeing scale, corrosion, or recurring fouling
These issues usually trace back to water chemistry drifting out of range, insufficient control, or inconsistent monitoring.

When you need tighter control of blowdown, water use, and cycles of concentration
Running higher cycles can reduce make-up water and blowdown, but it needs careful control to avoid scale and corrosion risk.

When biological growth risk needs active management
Warm, wet systems need a monitored biological control approach to limit microbial growth and protect system reliability.

What’s included

• Review of operating conditions, water source, and current issues (scale, corrosion, biofouling)

• Guidance on control parameters and monitoring cadence (including conductivity and blowdown control)

• Recommendations for chemical dosing strategy (scale/corrosion inhibition and biological control), aligned to your system and risk profile

• Advice on sidestream filtration where solids and airborne contamination are contributing to fouling

• Reporting and trend review so issues get caught early, not after performance drops

Common problems chemical treatment is designed to prevent

• Scaling that reduces heat transfer and drives up energy use

• Corrosion that shortens equipment life and damages piping, basins, and heat exchangers

• Biofouling that restricts flow, insulates surfaces, and increases operational risk

• Excessive blowdown and unstable cycles of concentration

What we need to get started

Send these details and we’ll come back with a treatment and monitoring approach that matches your plant and operating priorities:

• Site location and application (HVAC, process cooling, refrigeration, etc.)

• Make-up water source (town, bore, recycled) and any recent water test results

• Current operating setpoints (temperatures, flow, conductivity targets if known)

• Known issues (scale, corrosion, algae/biofilm, drift, high blowdown, carryover)

• Any existing treatment equipment (controllers, dosing pumps, filtration)

Supply, install, and ongoing support

Tower Thermal provides in-house support including inspections, audits, risk management planning, troubleshooting, refurbishment, parts, and turnkey installation services. Chemical treatment planning can be integrated into this wider service scope so the tower is maintained as a system, not as isolated components.
