Cooling Water Treatment Chemicals

We understand that cooling water systems are an integral part of process operations in many industries, with the possibility of productivity and product quality being adversely affected by scale, corrosion, fouling and microbiological contamination.
These problems can be very costly when they cause the loss of heat transfer, equipment failure, and health and safety concerns. Nalco uses a unique engineering approach, looking at your total system from mechanical, operational and chemical angles. We can provide best in class solutions tailored to your open recirculating, once-through, closed loop, geothermal, and process cooling systems.
Corrosion and Scale Control
Nalco’s corrosion and scale inhibitors feature traced chemistries designed for use with 3D TRASAR® control systems. With 3D TRASAR technology control, your system is monitored and feedrates are controlled for optimal, cost-effective performance.
Biocontrol
We offer a complete line of oxidizing and non-oxidizing biocides, algaecides and biodispersants that are effective in many different cooling water applications, including open recirculating cooling towers, once-through cooling systems, closed loop cooling systems, air washers, cooling ponds, and pasteurizers.
STA•BR•EX Antimicrobial Technology is the world’s first stable liquid bromine based antimicrobial, which makes it easier to apply and safer to handle than chlorine or other bromine-based products.
