Two Men Reviewing Cooling Water Towers

Cooling Water Treatment For Industrial Cooling Water Systems

We understand that your productivity and product quality could be impacted by your cooling water system.   Industrial cooling towers and closed loop efficiency can be adversely affected by corrosion, scaling, fouling and biological contamination.  Nalco Water offers a full array of cooling water treatment solutions including chemicals, equipment, automation and software, designed to safely optimise cooling system performance while conserving water and minimising waste.


Safety is a priority both with our cooling water chemical treatment programs and the environment.  3D TRASAR™ technology for cooling water systems can help you reach your sustainability goals by reducing water and energy use and making blowdown safer for discharge.

Safety is a priority both

Featured Cooling Water Treatment Programs

Clean Water Stream
Scale & Deposit Control for Cooling Water Systems

Fresh water is being added to cooling water towers to replace water lost through leaks or evaporation.  But this makeup water contains minerals, dirt, debris and other impurities that build up and insulate the metal surfaces.  Our forgiving polymers help prevent scale and deposits from forming over a wide operating range, are halogen stable, and can handle iron or aluminum contamination.

Closed Loop Cooling Water System with Treatment
Corrosion Inhibitors for Cooling Water Systems

Corrosion deteriorates metal and reduces its thickness and strength that can result in leaks, contamination or equipment failures in the heat exchangers and recirculating cooling water pipes in open towers and closed loops.
Our complete line includes Dual Cathodic Inhibitors for stressed industrial water, phosphate-free products, inorganic, all-organic and passivation programs.

Two Workers Talking In Front of Cooling Towers
Cooling Water Biocontrol for Cooling Water Systems

Cooling towers are constantly exposed to environmental contaminants and bacteria. This requires a rapid response, accurate detection and a tailored programme to control biological growth. Nalco Water will work with you to design a cooling water biocontrol programme from our complete line of oxidizing and non-oxidizing biocides, algaecides and biodispersants.

Closed Loop Cooling Water Pipes
Chlorine Dioxide

Nalco Water offers a variety of chlorine dioxide offerings suited for applications from traditional cooling water microbial control to secondary disinfection.  Purate™ technology was developed with for large industrial systems while AccuPro™ is suited for medium to small cooling water systems. 

Microscopic Representation of Legionella
Legionella Control

Nalco Water is uniquely qualified to help you manage and reduce Legionella risk as the global leader in water safety for over 30 years.  Let us develop a customized Water Management Plan that incorporate the required elements of ASHRAE Standard 188 for your facility.
