Metallurgy-driven selection
Steel-only loops differ from mixed-metal tower systems. Provide steel/copper/stainless/aluminum presence to match chemistry.
Product Water Treatment
Corrosion Inhibitor (Cooling Water)
Cooling-water inhibitor designed to help control corrosion in open recirculating and/or closed-loop systems (grade dependent) by forming protective films and stabilizing electrochemical conditions across common metallurgies.
Open recirculating towers
Closed loops / chilled water
Steel & copper alloy protection
Program blends available
Drum / IBC / bulk
Packaging: drums / IBC / bulk (as applicable)
Documentation: SDS / COA / TDS on request
Lead time depends on chemistry package, lane & volume
Commercial note: We can supply multiple inhibitor “packages” (e.g., phosphonate/azole blends; molybdate or zinc-based options; closed-loop nitrite/molybdate-style programs where permitted). Share your metallurgy and water analysis to match a cost-effective program with the right monitoring plan.
What it does
Cooling-water corrosion inhibitors reduce metal loss by building protective films on surfaces and controlling key corrosion drivers such as dissolved oxygen, pH, ionic strength, and galvanic effects between dissimilar metals. The right selection depends on system type (open tower vs closed loop), metallurgy, water chemistry, and operating conditions.
Film formation
Promotes protective layers on carbon steel and copper alloys (chemistry package dependent) to reduce corrosion rates.
Program compatibility
Designed to work alongside scale control and microbiological control programs (biocide compatibility must be confirmed).
Monitoring-ready
Grades can be aligned to measurable control parameters (e.g., residual actives, pH, conductivity, corrosion coupon targets).
Typical system coverage
Open recirculating cooling towers (evaporative systems) and closed loops/chilled water circuits (grade dependent). Metallurgy commonly includes mild steel, copper/brass, stainless steel, and mixed-metal systems.
Common chemistry building blocks
Phosphonates (program support), azoles (copper alloy protection), molybdate or zinc (corrosion inhibitors), polymers/film-formers, and stabilizers—selected to fit your water and regulatory constraints.
Note: Final chemistry selection and dosage must be validated against your system water analysis, cycles of concentration, and plant procedures.
Applications
Typical usage patterns. Tell us your process and constraints and we’ll align the right specification and inhibitor package.
- Open recirculating cooling towers: corrosion control for mixed-metal systems under evaporative concentration
- Closed-loop heating/cooling circuits: inhibitor packages for oxygen control and film protection (grade dependent)
- Chilled water loops: low-corrosion programs with stable residual control (grade dependent)
- Industrial process cooling: compatibility-oriented programs where water chemistry and metallurgy vary by plant
Where problems typically originate
Corrosion risk increases with high chlorides, high conductivity/TDS, low alkalinity, poor pH control, high dissolved oxygen, under-deposit conditions, stagnant zones, and mixed metallurgy. A matched inhibitor package plus monitoring is the most reliable route to stable control.
Technical notes for specification
Procurement-ready parameters for aligning the correct corrosion inhibitor package and documentation set.
Water chemistry tolerance
Chlorides, sulfates, alkalinity, and conductivity influence inhibitor performance and dosage—share limits and typical values.
Program integration
Coordinate with scale inhibitors, dispersants, and biocides. Feed strategy and compatibility are part of the final recommendation.
