Why Use Anti-Scale, Anti-Rust, and Anti-Algae Chemicals in Industrial Systems?
Cooling Towers, Boilers, and Heat Exchangers are vital components in industrial production processes.
The accumulation of scale, rust, and algae/biofilm can reduce heat transfer efficiency, increase power consumption, and accelerate metal corrosion within machinery.
Using the right chemical protection program extends equipment lifespan, reduces maintenance costs, enhances operational safety, and improves production efficiency sustainably.
Main Ingredients of Runpar’s Anti-Scale, Anti-Rust, and Anti-Algae Chemicals
Runpar’s formulations are designed using chemical engineering principles and tailored to suit Thailand’s water quality, classified into four main active groups:
1. Scale Inhibitors & Dispersants
Main Ingredient
Function
Typical Dosage Range
Phosphonates (HEDP, ATMP, PBTC)
Binds Ca²⁺/Mg²⁺ ions to prevent carbonate/sulfate crystallization
1–10 ppm
Polymer (PAA, AA/AMPS)
Disperses scale and silica; prevents deposition on heat exchanger surfaces
2–20 ppm
Zinc Salts (Zn²⁺)
Acts as a cathodic corrosion inhibitor for steel
0.2–1.0 ppm as Zn
Silicate
Forms protective silicate film for closed/chiller systems
1–5 ppm
🧩Key Features of Runpar Formulation
✅ Effective even under high COC (Cycles of Concentration)
✅ Non-reactive with iron or copper
✅ Proven performance through real Cooling Tower field testing
2. Corrosion Inhibitors
Main Ingredient
Function
Typical Dosage Range
Orthophosphate / Polyphosphate
Forms protective film on steel
1–6 ppm as PO₄³⁻
Molybdate
Protects closed systems from corrosion
50–250 ppm
Nitrite (NO₂⁻)
Prevents rust in chiller systems
300–1200 ppm
Benzotriazole / Tolyltriazole (BTA/TTA)
Protects copper and alloys
0.5–3 ppm
Runpar’s advanced Filming Polymer technology creates a thin, durable protective layer on metal surfaces without sticky residue or excessive film buildup.
3. Biocides & Biodispersants (Microbial and Algae Control)
Type
Active Ingredient
Key Benefit
Oxidizing Biocide
Sodium hypochlorite, Stabilized Bromine, Chlorine dioxide
Fast-acting bacteria and algae control
Non-Oxidizing Biocide
Isothiazolinone, DBNPA, Glutaraldehyde, THPS
Destroys biofilm and chlorine-resistant bacteria
Biodispersant
Nonionic surfactant
Disrupts microbial film, enhances biocide performance
💧 Runpar’s Dual Biocide Program prevents microbial resistance and ensures long-term system hygiene for Cooling Towers and Chillers.
4. pH Control & Oxygen Scavengers
System
Chemical Used
Standard Range
Cooling Tower
NaOH / H₂SO₄
pH 7.5–8.5
Boiler
Sodium sulfite, DEHA, Carbohydrazide
DO < 20 ppb
Closed Loop/Chiller
Nitrite/Molybdate
pH 8.5–10.0
Runpar’s precise formulation ensures accurate water balance, minimizing corrosion and extending equipment lifespan by 30–50%.
Application by System Type
Cooling Tower
• Low-P / P-free formula – heavy metal free
• ORP control at 650–800 mV
• Keeps fill and basin clean
• Extends the life of heat exchangers and pumps
Boiler
• Prevents scale buildup inside boilers
• Uses Hydrazine-free Oxygen Scavengers
• Reduces energy loss caused by thick scale deposits
Heat Exchanger / Chiller
