Corrosion and scale inhibitor FCA1100

FCA1100 Corrosion and Scale Inhibitor is a multifunctional composite water treatment formulation applicated specifically for industrial open recirculating cooling water systems. Leveraging triple-action synergy of organophosphonate chelation, corrosion-inhibiting film formation, and multi-copolymer dispersion, it delivers simultaneous scale prevention and comprehensive corrosion protection under high-hardness, high-alkalinity, and broad pH conditions. Effectively suppresses calcium carbonate, calcium sulfate scaling while forming a dense protective layer on carbon steel, copper alloys, stainless steel, and aluminum surfaces—significantly extending heat exchanger and piping system service life. Widely deployed across power generation, metallurgy, oil refining, and chemical industries, FCA1100 supports operational efficiency, reduces maintenance costs, and enables safe, economical, and sustainable water management.

FCA1100 Corrosion and Scale Inhibitor

Product Features

Synergistic Composite Formula: Scientifically blended organophosphonates, high-efficiency corrosion inhibitors, multi-component copolymer dispersants, and functional additives for enhanced scale/corrosion control.
Broad-Spectrum Metal Protection: Provides balanced corrosion inhibition for carbon steel, stainless steel, copper alloys, and aluminum; corrosion rates comply with GB/T 18175 standards.
Robust Water Adaptability: Performs reliably in challenging conditions (hardness ≤1000 mg/L as CaCO₃, high alkalinity, pH 7.0–9.2) with strong shock-load resistance.
Superior Chemical Compatibility: Stable with oxidizing/non-oxidizing biocides; no antagonistic effects, simplifying chemical management protocols.
Eco-Safe & User-Friendly: Low-toxicity formulation (OECD-tested); liquid form enables easy dosing and automation with minimal operational risk.
Cost-Optimized Operation: Recommended dosage 50–80 mg/L; precisely tailored to water quality for optimal performance-to-cost balance.

Dosage Instructions

Application Scope: Designed for open recirculating cooling water systems in power, metallurgy, oil refining, and chemical industries—especially effective in high-hardness, high-alkalinity, and high-pH feedwater conditions.
Dosing Method: Continuous injection via metering pump at system return header. Recommended dosage: 50–80 mg/L; adjust based on water analysis (Ca²⁺, HCO₃^–, Cl^–, etc.) and corrosion/scale monitoring data.
Critical Notes:
Monitor system pH (maintain 7.0–9.2), turbidity, and corrosion coupon results regularly to optimize dosing;
When used with biocides, maintain dosing interval or consult technical engineers to avoid localized over-concentration;
Insufficient dosage increases scaling/corrosion risk; excessive dosage may elevate blowdown load.

Packing and Storage

25 kg plastic drums; custom packaging available upon request. Store in a cool, dry, well-ventilated area away from direct sunlight and high temperatures.
