Assess Microbiological Risk, Corrosion, and Chemical Balance in Your Chilled Water System
Chilled water systems circulate treated water through air handlers, coils, and piping to deliver cooling throughout a building. Poor water quality — whether from biological fouling, corrosion, or chemical imbalance — reduces cooling capacity, increases energy consumption, and accelerates equipment wear. Full Spectrum Environmental provides professional chilled water system water quality testing for commercial buildings and institutional facilities across Florida.
What Does Chilled Water System Testing Evaluate?
A chilled water system assessment evaluates the chemical and microbiological quality of the circulating water, the condition of system components, and the adequacy of the current treatment program. Because chilled water systems are nominally closed systems, problems tend to concentrate over time — making periodic testing essential for long-term system health.
Water Chemistry Analysis
We test pH, alkalinity, conductivity, hardness, and inhibitor residual in the chilled water to evaluate whether loop chemistry is within specifications. Improper pH and depleted inhibitor are the primary drivers of corrosion in chilled water systems.
Microbiological Assessment
We test for total bacteria counts, sulfate-reducing bacteria, and other microbiological indicators that can cause corrosion, generate hydrogen sulfide, and create biofilm deposits that reduce heat transfer and increase pressure drop through system components.
Corrosion Monitoring
Dissolved iron, copper, and other corrosion markers in the circulating water indicate active degradation of system components. We quantify these markers to assess corrosion rates and evaluate whether current inhibitor programs are providing adequate protection.
Suspended Solids & System Cleanliness
Suspended particulate in chilled water systems accelerates wear on pump seals, impellers, and valve seats. We measure turbidity and total suspended solids and assess whether dirt separators and strainers are performing as intended.
Glycol Concentration & Condition
For systems using glycol freeze protection, we evaluate glycol concentration, pH, inhibitor content, and contamination that can degrade glycol protection and damage system components over time.
System Performance Indicators
We evaluate temperature differential across the system, pressure drop indicators, and available operational data to correlate water quality findings with system performance characteristics.
Performance and Cost Implications
Fouled chilled water coils and heat exchangers in a mid-size commercial building can add tens of thousands of dollars in unnecessary energy costs over a cooling season. Early detection of water quality problems — before fouling and corrosion become severe — is far less expensive than coil cleaning, heat exchanger replacement, or chiller repair.
- Coil Fouling: Biological deposits and scale on chilled water coils reduce heat transfer, increase supply air temperatures, and drive up energy consumption
- Pipe Corrosion: Internally corroded piping generates iron deposits that foul downstream coils and increase system maintenance costs
- Pump & Seal Wear: Suspended solids in circulating water accelerate wear on rotating equipment, increasing maintenance costs and failure risk
- Glycol Degradation: Depleted or contaminated glycol loses freeze protection capacity and becomes corrosive to system metals
- Treatment Program Drift: Inhibitor depletion in closed systems occurs gradually — regular testing is the only way to detect it before damage occurs

Chilled Water System Risk Factors in Florida Commercial Buildings
Florida’s climate demands year-round chilled water production, placing mechanical systems under continuous operational stress. Chilled water systems that run without interruption accumulate water chemistry problems faster than systems in seasonal climates — and deferred testing means problems compound before they are identified. Corrosion, scale, and microbiological contamination in chilled water loops reduce chiller efficiency, foul heat exchangers, and cause premature equipment failure. Our risk assessments identify the specific vulnerabilities in your system before they become capital expenditures.
High-risk conditions in Florida chilled water systems include glycol degradation in systems using inhibited glycol, biological activity in stagnant system segments, corrosion from dissimilar metal contact in aging piping systems, and scale formation at heat exchanger surfaces from high-hardness makeup water. We assess these parameters alongside operational data to provide a complete risk picture for your facilities team.
