Nalco 93033 -

Whether you manage a power plant, a chemical processing facility, a commercial HVAC system, or a steel mill, maintaining the efficiency of your cooling tower is paramount. Scale, corrosion, and biological fouling are the three silent killers of thermal efficiency. Nalco 93033, manufactured by Ecolab’s Nalco Water division, is designed to combat all three simultaneously.

| Parameter | Target Range | | :--- | :--- | | Orthophosphate (as PO₄) | 4 – 8 mg/L | | pH | 7.0 – 8.0 | | Total Hardness (as CaCO₃) | 50 – 600 mg/L | | Conductivity | < 3,500 µS/cm | Inject Nalco 93033 directly into the cooling water basin or into the recirculating pump suction line. Avoid feeding immediately before filtration systems. Use a chemical metering pump (diaphragm type) with chemical-resistant wetted parts (PVC, Viton, Teflon). Calculating Feed Rate A typical starting dose for a new system or after a cleaning is 50-100 ppm of product based on system volume. For continuous feed, use the formula: nalco 93033

This article provides an exhaustive overview of Nalco 93033—covering its chemistry, application methods, dosage rates, safety protocols, and why it remains a gold standard in the water treatment industry. Nalco 93033 is a liquid cooling water treatment additive primarily used in open recirculating cooling water systems. It is classified as a stabilized phosphate-based corrosion inhibitor combined with a polymer dispersant. Whether you manage a power plant, a chemical
