Stable chemistry for closed water circuits.
Chemical selection depends on water analysis, metallurgy, operating temperature, system volume, glycol presence, make-up rate, contamination history and trend data.
Analysis First
Water analysis before product recommendation.
TDS, SDS and certificates are shared upon request.
Closed loop systems behave differently from open cooling circuits. The water is retained for long periods, so corrosion products, oxygen ingress, low inhibitor residuals, pH drift, microbial activity, glycol degradation by-products and suspended deposits can remain inside the circuit. This makes closed-loop treatment a long-term control program rather than a one-time chemical addition. Watel Analyses should be presented as Liberta’s data-based technical service support platform. It helps structure entered field/lab data and historical results for trend-based evaluation, risk review and action planning. It must not be described as real-time online monitoring or automatic chemical control.
Multi-metal corrosion-control programs for steel, copper alloys, brass, stainless steel and selected aluminum-containing closed loop systems, subject to application review.

Core product card. Avoid universal metallurgy compatibility claims.
Oxidizing and non-oxidizing biocide options may be evaluated for lower-temperature closed loop systems where microbiological risk is relevant.
Sterilizes the closed loop. / Eliminates Legionella. / Guarantees microbiological control.
Biocide selection depends on metallurgy, elastomer compatibility, glycol presence, pH, operating temperature and local regulatory requirements.
Cleaning and flushing should be presented as a controlled technical step, not as an optional cosmetic service. In closed loops with corrosion products, deposits, poor historical treatment, construction debris or glycol degradation by-products, cleaning may be required before a stable inhibitor program can be established.
Flushing and startup support before final chemical treatment.
Cleaning route should be reviewed before inhibitor optimization.
pH, conductivity, hardness, alkalinity, chloride, sulfate, iron, copper and suspended solids.
Supports condition assessment and chemistry drift review.
Inhibitor residuals, glycol percentage, make-up frequency, corrosion coupon notes and filtration observations where available.
Supports stable protection in retained-water circuits where chemistry remains inside the system for extended periods.
Program can be aligned with mixed-metal systems, aluminum-containing equipment and sensitive metallurgy where applicable.
Supports control of hardness leakage, corrosion by-products and suspended deposits that may impair heat transfer or flow.
Liberta reviews water analysis, system volume, metallurgy, operating temperature, glycol data and historical treatment conditions.
Corrosion/scale program, biocide option, cleaning/flushing route or glycol-loop support is selected according to system data.
Metallurgy, elastomer, glycol and regulatory compatibility are checked where relevant, especially for biocide and cleaning chemistry.
Corrosion, pH stability, deposit control, biocide options below 55-60 C and trend-based monitoring.
Use temperature and building-operation context carefully.
Low-temperature microbiological risk, glycol presence, corrosion and deposit control.
