Chemical Water Treatment
We're your boiler, cooling tower, and closed-loop water treatment chemical company. Reduce operational costs, prolong equipment life, and ensure compliance with our industrial water treatment chemicals, service, and equipment.
Why You Need Industrial Water Treatment Chemicals
Without proper industrial water treatment, the health of your personnel and the integrity of your equipment are at risk. Corrosion, scale, and biological growth impact the efficiency, safety, and longevity of your heating, cooling, and process water systems.

It only takes 1/32 inch (0.8 mm) of scale to raise boiler fuel use by 2–7%, depending on the type of scale (US Department of Energy). The end-result, increased fuel and electricity costs.

Corrosion can eat your system from the inside-out. And reduce your system lifespan, resulting in costly repairs or replacement.

Microbiological growth results in health and safety risks. Legionella exposure can cause a fatal form of pneumonia known as Legionnaires’ disease.
That’s why you need the right water treatment chemical supplier and chemical water treatment program.

FAQ: Chemical Water Treatment Solutions
Maintaining water quality is essential for the efficiency and reliability of systems like boilers, cooling towers, and closed loops. High-quality chemical water treatment ensures these systems run efficiently and last longer by preventing scale, corrosion, and microbial growth. It’s crucial to ask the right questions when choosing a water treatment solution to protect your investment and guarantee years of reliable service. Contact us to learn more about how our chemical water treatment programs reduce resource use, increase efficiency, and extend system life.
Effective water treatment program costs vary by the system (whether a boiler, cooling tower, or closed loop) and size. All systems require ongoing chemical treatment, water testing, and maintenance. Some systems will benefit from automation equipment.
Water treatment costs represent just 2-4% of your total operating cost for steam boilers and cooling systems, but help you achieve the lowest operating costs.
Effective treatment minimizes energy use, repairs, and optimizes water use—leading to substantial net savings. Combined with regular system maintenance, effective water treatment also prevents costly breakdowns and ensures systems operate at peak efficiency.
At Guardian Chemicals, our service representatives optimize your system treatment for maximum efficiency and reliability. Our water treatment programs: reduce energy consumption; reduce downtime, repairs, and maintenance; reduce health & safety risks; reduce water consumption and environmental impact; and extend system life.
Implement an effective water treatment program using high-quality chemicals, regular monitoring and water testing, and maintenance. Train staff on water treatment best practices including water testing, acceptable parameters, and proper dosage to mitigate hidden costs.
Ignoring treatment can lead to catastrophic system failures, significant repair or replacement expenses, and potential regulatory fines for non-compliance with safety standards. In the case of Legionella outbreaks, financial risk is increased due to reputational damage and potential lawsuits.
As a reputable boiler chemical treatment company, we specialize in customized chemical solutions for your boiler maintenance needs. Chemical water treatment solutions include programs for boilers, cooling systems including cooling towers, closed loops, and pretreatment. All chemical water treatment programs focus on preventing corrosion, scale, and microbial growth to maximize efficiency and asset life.
Customized programs prevent corrosion, deposition, and biological growth in cooling towers and water systems.
Chemicals used for boiler treatment include oxygen scavengers, corrosion inhibitors, neutralizing amines, and dispersants to control scale and corrosion.
Biocides are essential in water treatment programs to control microbial growth, which can lead to biofilm formation, corrosion, and reduced system efficiency. They help maintain clean and efficient operations in both cooling and boiler systems.
