Cooling Tower Biocide

Description

1. Product Overview
This product is a high-performance, broad-spectrum industrial biocide engineered specifically for recirculating cooling water systems. It is used to control microbial fouling—including bacteria, algae, and Legionella—that undermines heat exchange efficiency and accelerates asset corrosion. The key value proposition is a measurable reduction in unplanned downtime and a 15–20% extension of equipment service life through superior slime control. With global water scarcity tightening discharge regulations, this biocide is strategically critical for asset-intensive industries seeking operational resilience and regulatory compliance.

2. Key Specifications & Technical Characteristics

• Chemical composition: Stabilized blend of Isothiazolinone derivatives (CMIT/MIT ratio 3:1) plus synergistic tetrakis(hydroxymethyl)phosphonium sulfate (THPS)

• Purity level: ≥98% active ingredient concentration; heavy metals <2 ppm

• Physical characteristics: Clear, pale-yellow liquid; pH (neat) 3.5–5.0; density 1.18–1.22 g/cm³ at 20°C; viscosity <50 cP

• Packaging options: 25 L HDPE jerricans, 200 L closed-head drums, 1,000 L IBC totes, and bulk isotanks

• Shelf life: 24 months in original unopened container stored between 5–35°C; no crystallization or potency loss

3. Core Industrial Applications

• Power generation (thermal & nuclear): Prevents biofilm formation in condenser tubes and cooling towers, reducing back-pressure and improving thermal efficiency by 4–7%.

• Petrochemical & refining: Used in open recirculating and once-through systems to eliminate sulfate-reducing bacteria (SRB) that cause pitting corrosion in carbon steel heat exchangers.

• HVAC for large-scale infrastructure (airports, data centers): Controls Legionella pneumophila to below detection limits (＜10 CFU/mL) without damaging aluminum or copper components.

• Why better: Unlike oxidative biocides (chlorine/bromine), this product provides 7–10 days of residual protection, works across pH 6.5–9.0, and does not form toxic trihalomethanes (THMs) or AOX, lowering chemical storage risk and environmental reporting burden.

4. Competitive Advantages

• Quality consistency: ISO 9001:2025 certified; each batch tested for minimum inhibitory concentration (MIC) against Pseudomonas aeruginosa ATCC 15442 with coefficient of variation <3%.

• Supply reliability: Dual-sourced raw materials and three geographically dispersed blending plants (Americas, EMEA, APAC) ensure 99.6% on-time-in-full (OTIF) track record.

• Logistics capability: Dangerous goods classified as UN 3082 (Environmentally Hazardous Substance, liquid, n.o.s.), Packing Group III – optimized for non-haz re-classification in many jurisdictions when shipped in sealed IBCs.

• Price competitiveness: Tiered pricing based on annual volume (10,000–500,000+ liters) with fixed 12-month contracts to hedge raw material volatility.

• Sustainability & technical support: Fully biodegradable under aerobic conditions (OECD 301F); supplied with full REACH, TSCA, and K-REACH dossiers; includes free quarterly on-site dosing optimization audits via in-house chemical engineers.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 4,000 liters (net) – equivalent to 4 x 1,000 L IBCs or 16 x 200 L drums

• Bulk 20MT loading capacity: 20 metric tons (net) per 20-ft general-purpose container, using 80 x 200 L drums on GMA-compliant pallets, or 20 x 1,000 L IBCs (tiered and strapped)

• Lead time: 15 days ex-works for MOQ; 30 days for bulk 20MT container load (FCL) from regional distribution hub. Expedited air freight available for emergency orders (minimum 5,000 liters).
