While the exact proprietary formula of Nalco 93033 is protected, technical data sheets and industrial analyses confirm it belongs to the family of stabilized phosphate-based inhibitors. Its key active ingredients include:
| Feature | Nalco 93033 | Traditional Molybdate | Nitrite-based | |---------|-------------|----------------------|----------------| | Corrosion control | Excellent (Fe & Cu) | Good (Fe only) | Good but toxic | | Scale control | Excellent (CaCO₃, CaPO₄) | Poor | Poor | | Environmental profile | Low aquatic toxicity if neutralized | Moderate (Mo is regulated in some regions) | High toxicity | | Cost per ppm active | Moderate | High | Low (but requires precise control) |
If your system operates at high temperatures (>140°F or 60°C) or low pH (<6.5), Nalco 93033’s performance may degrade—consult with a Nalco representative for those niche applications.
For over two decades, Nalco 93033 has earned its reputation as a reliable, cost-effective cooling water treatment chemical. Its balanced chemistry—phosphate for passivation, polymer for scale control, and azole for copper protection—solves the major failure modes of HVAC and industrial cooling systems. To achieve optimal results, pair Nalco 93033 with regular water analysis, automated bleed control, and quarterly system inspections.
Before implementing Nalco 93033 in your facility, request a water audit from a certified Nalco water treatment specialist. Proper startup and monitoring will ensure your cooling tower operates at peak efficiency, reducing energy costs by up to 15% and extending heat exchanger life by years.

NALCO 93033 is a specialized cooling water treatment additive primarily used to prevent corrosion and scale in closed cooling systems. It is a proprietary chemical formulation often utilized in industrial laser systems, such as those from TRUMPF, to maintain the integrity of cooling circuits. Key Technical Features
Chemical Function: Primarily acts as a corrosion inhibitor and biocide precursor (often associated with sodium hypochlorite for chlorine dioxide generation).
Shelf Life: One year when stored at a maximum temperature of ( ).
Certifications: Registered with the NSF International for use in and around food processing areas where there is no possibility of food contact. Safety and Handling Requirements
Physical Hazards: The substance is combustible and should be kept away from heat and open flames. Health Hazards: While the exact proprietary formula of Nalco 93033
Skin/Eyes: Can cause moderate irritation. Goggles and face shields are required for handling.
Inhalation: Prolonged inhalation may be harmful, potentially leading to nausea, dizziness, or central nervous system depression.
PPE Recommendations: Wear chemical-resistant gloves, protective clothing, and eye protection during any preparation or transfer process. Storage and Compatibility
Containment: Storage areas must be bunded (at 110% of the largest tank capacity) to prevent environmental contamination.
Classification: Typically grouped with alkali or non-hazardous solvents depending on the specific facility protocol, but must be kept closed when not in use to prevent vapor accumulation. Preparation and Application Disclaimer: This article is for informational purposes only
Monitoring: Users should check water levels on the system's indicator and top up the cooling circuit as needed.
Dilution: Specific concentrations depend on the system volume; users should refer to their equipment's technical manual (e.g., TRUMPF TT59EN) for precise dosing ratios. Nalco 93033 Chemical Treatment Overview | PDF - Scribd
Cause: Underfeeding or phosphate dropout due to low pH. Solution: Check orthophosphate levels via field test kit. Increase Nalco 93033 feed and verify pH >7.2.
While always check local regulations, Nalco 93033 is often approved for use in indirect contact cooling loops, provided proper leak detection is in place. It is not for potable water systems, but it is safe for standard non-contact cooling applications.
With the rising demand for efficient cooling of server farms, Nalco 93033’s low-foaming nature and superior scale control help maintain closed-loop and open-loop cooling systems without clogging fine-bore cooling plates.
Nalco 93033 is an acidic liquid (pH 1.5-3.5). It is not classified as acutely toxic, but it is corrosive to eyes and skin.
