Closed Loop Water Treatment Services

masthead-logo-icon

Closed loop systems enclose water within the pipes for efficient water conservation and improved equipment maintenance. While these systems are excellent in preserving water volume and quality, they are susceptible to leaks that can lead to contamination-forming corrosion and microbial growth. These risks in the cooling water may ultimately cause a total system failure.

Chardon Laboratories provides effective closed-loop water treatment services to address various risks, prevent leakage, and other troublesome issues from occurring. Learn more about our water treatment services to maximize productivity and prolong the life of your system.

Specialized Treatment Techniques

The right solutions are vital for preventing corrosion, scale, pitting and microbial growth. At Chardon, our comprehensive closed loop water treatment services include specialized techniques. When you partner with us, we’ll assess your water treatment needs and choose a chemical that best serves your specific applications, ensuring maximum system performance and efficiency.

Corrosion Inhibitors

Mixed steel and copper components are vulnerable to galvanic attack, in which dissimilar metals in the same fluid accelerate corrosion of the less noble metal. We select the appropriate closed loop corrosion inhibitor for your system, from phosphate and nitrite to molybdate-based options, to passivate metal surfaces and slow oxidation. We confirm glycol compatibility before treatment begins.

Microbial Control

Nitrate-reducing and sulfate-reducing bacteria thrive in the low-oxygen environment of closed loops, driving microbiologically influenced corrosion (MIC) that pits metal surfaces and contributes to leaks. As iron corrodes, it produces iron oxide deposits that accumulate as black water, a visible sign that biological activity has taken hold in the loop. We apply nonoxidizing biocides, including isothiazolinone and glutaraldehyde-based treatments, to address aerobic and anaerobic bacteria and help control biofilm development.

pH Management

For carbon steel systems, an alkaline pH promotes passivation and helps resist deterioration. We use alkalinity builders to maintain pH within the noncorrosive range, and acid-based treatments where elevated pH increases scale risk. Where colloidal iron is present, polymer-based treatments help disperse particles and prevent deposits from forming on heat transfer surfaces. We track conductivity and iron levels alongside pH, catching chemistry drift between service visits before it affects heat transfer.

Is Your Closed Loop System at Risk? [Warning Signs]

Closed loop systems can deteriorate gradually with few visible signs. If any of the following describe your system, it may be time for a professional evaluation:

  • System water appears dark or discolored, a common sign of iron oxide accumulation
  • Iron levels in water samples exceed 2.0 parts per million (ppm) or copper levels are elevated
  • pH readings fall outside the 8.0-10.0 range for steel-based systems
  • Glycol concentration has not been tested or adjusted in the past 12 months
  • Filters are clogging more frequently than in previous service cycles
  • Unexplained pressure drops or flow restrictions have developed in the loop
  • Makeup water consumption has increased, which can indicate a developing leak
  • The system is operating without a documented chemical treatment plan
  • Pipe or component inspections have revealed pitting, rust staining or surface degradation

If you detect any of these signs, schedule a free survey with Chardon.

Our Proven Closed Loop Treatment Process

Caring for a closed loop water system entails:

  1. Running a full system diagnosis: We inspect for corrosion, leaks, iron and copper levels, pH, glycol concentration and biological activity. Our team delivers a full findings report after the visit.
  2. Creating an application-specific chemical treatment program: Based on metallurgy, water chemistry and operating conditions, we develop a closed loop system water treatment plan specifying the right inhibitors, biocides and scale controls for your application.
  3. Cleaning the system if needed: When iron oxide deposits, biofilm or accumulated debris are present, we flush and clean the loop before the treatment program begins to maximize chemical efficacy.
  4. Performing continuous treatment and oversight: Our experts test and adjust water chemistry at scheduled intervals, monitoring pH, inhibitor concentrations, and other factors to catch chemistry drift early.
