Culligan Water Systems’ Cooling Water Treatment program inhibits and prevents corrosion, scale and microbiological fouling in recirculating and closed water systems. The program minimizes makeup water and sewer costs and maximizes water use. Routine service visits by expert personnel provide detailed reports, training, and service that improve your system’s overall operation.

Culligan Water Systems can provide a wide range of chemical solutions for all aspects of cooling systems and all manners of discharge requirements:

  • Open recirculating systems – Cooling Towers
  • Closed loop systems – Chill/Hot Water Loops, Air Washers
  • All-organic programs – eliminates heavy metal usage
  • Bacteria and Algae control and Legionella Risk Minimization
  • Online or offline chemical cleaning – remove build up of corrosion or scale deposition to improve heat transfer efficiency

Combined with our established, high-grade filtration systems that will improve system protection and reduce chemical consumption, our Control Equipment Solutions, and our Culligan Delivery options, Culligan Water Systems is dedicated to providing the most efficient and effective use of water, chemicals, and energy, along with maintaining maximum equipment longevity.


  • Asset protection
  • Maintain thermal efficiencies
  • Optimization of water usage
  • Health and safety

Chemical Cleaning

Deposited minerals and iron along heat exchange points can vastly increase the energy usage for a chiller and eliminate cooling efficiency in a heat exchanger. Ask your Culligan service representative about the benefits of chemical cleaning to restore efficiency and minimize future energy costs.

Corrosion Prevention

Corrosion WILL occur in cooling towers and closed loops without chemical protection. Corrosion not only damages the equipment, it can contribute to issues with deposition and microbiological growth. Protect your equipment and your investment with a Culligan chemical program designed to provide excellent corrosion prevention, while monitoring this protection with a Culligan quarterly corrosion rate analysis.

Deposition Prevention

Dissolved minerals naturally accumulate in cooling tower water. Deposition of these dissolved solids can occur along all points of heat exchange, greatly reducing efficiencies in chiller condensers, plate and frame heat exchangers, and air handling units. This can also lead to under-deposit corrosion and contribute to microbiological growth. Maximize your energy efficiency and prevent deposition problems with a Culligan chemical program.

Microbiological Prevention

Cooling towers provide an ideal environment for bacteria growth, causing health and safety concerns. Biofilms can be every bit as insulating as mineral deposition, minimizing energy efficiency, and can also lead to microbiologically induced corrosion. In a closed loop, certain corrosion prevention programs can actually feed and promote bacteria development. Minimize your risk for Legionella and other microbiological based concerns with a properly applied Culligan chemical program.


From membrane reverse osmosis to deionization and commercial water softening, and from design to installation, Culligan's fast-to-market solutions feature revolutionary designs for commercial water treatment that are completely customizable to your business needs.


Utilize Culligan’s chemical water treatment programs to prevent corrosion, deposition, and microbiological growth in your Cooling and Heating Systems. Protect your cooling towers and chillers, steam boilers and steam lines, closed loops and equipment, all while minimizing water and energy consumption, facilities costs, and downtime.
