Cooling Water Scale Inhibitor — Heat exchanger protection

Description

1. Product Overview

A synergistic blend of threshold scale inhibitors and dispersants specifically formulated to control calcium carbonate, calcium sulfate, and iron fouling in industrial cooling water systems. Primary use: protecting heat exchangers, condensers, and chiller barrels in power plants, refineries, HVAC, and chemical processing. The key value proposition is a measurable reduction in heat transfer resistance and unplanned shutdowns. Strategically important as water stress and stricter discharge regulations make efficient reuse and low‑blowdown operation critical for industrial competitiveness.

2. Key Specifications & Technical Characteristics

• Chemical composition: Proprietary blend of polycarboxylates, phosphinocarboxylic acid, and non‑ionic dispersants (no heavy metals, low phosphorus option available)

• Purity / activity: Active content ≥ 38% by weight

• Physical form: Clear amber liquid; density 1.18–1.22 g/cm³ at 20°C; pH (as supplied) 3.5–4.5; viscosity < 50 cP

• Packaging options: 25 kg HDPE jerrycans, 220 kg drums, 1,000 kg IBC totes, and bulk isotanks

• Shelf life: 24 months in unopened, original containers stored between 5–40°C, away from direct sunlight

3. Core Industrial Applications

• Primary industries: Power generation (cooling towers), petrochemicals, steel mills, HVAC for large facilities, food & beverage (ammonia condensers), and district cooling.

• Operational use cases: Continuous feed to recirculating cooling water at 5–30 ppm; also used in high‑cycle‑of‑concentration (up to 8 cycles) or low‑quality make‑up water.

• Performance advantage: Outperforms standard phosphonates by maintaining efficacy at bulk water temperatures up to 70°C and skin temperatures >120°C, where organophosphonates degrade into orthophosphate and cause calcium phosphate scale.

• Cost/efficiency benefit: Extends heat exchanger cleaning intervals from 3 months to >12 months; reduces pressure drop increase by 60% compared to untreated or poorly treated systems.

4. Competitive Advantages

• Quality consistency: ISO 9001:2025 certified production; each batch validated by FTIR and deposit control bench test (simulated heat exchanger).

• Supply reliability: Dual manufacturing sites (Asia & Middle East) with 5,000 MT/month capacity; safety stock levels >30% of forecast.

• Logistics capability: Direct container loading from three warehouses; lead time 14 days to any major port.

• Price competitiveness: Tier‑1 performance at 15–20% lower dosage rates vs. leading European brands, reducing delivered cost per MT of water treated.

• Sustainability: Low‑phosphorus option (<2% P) meets strict discharge limits (e.g., China GB 8978, EU Best Available Techniques).

• Technical support: Full Langelier Saturation Index calculator, compatibility study with biocides (oxidizing/non‑oxidizing), and on‑site dosage optimization included for contract volumes.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20 MT (one flexible IBC or drum pallet mix allowed)

• Bulk loading capacity: 24 MT per 20-foot container (IBCs or drums) / 26 MT per flexitank in 20-foot container

• Standard incoterms: FOB, CIF, CFR major ports (Houston, Rotterdam, Shanghai, Jebel Ali)
