NALCO 93033 is a specialized cooling system additive used primarily in industrial machinery, such as laser systems and engines, to prevent corrosion and mineral buildup.

Below is a story illustrating its critical role in maintaining industrial operations. The Pulse of the Factory: A Story of NALCO 93033

In the heart of a high-tech manufacturing plant, the air hummed with the rhythmic pulse of TRUMPF industrial lasers. These machines were the lifeblood of the facility, cutting through steel with surgical precision. But even the strongest steel-cutters have a vulnerability:

Inside the complex network of each laser, a cooling circuit circulated thousands of liters of water to keep the optics and resonators from overheating. Without proper care, this water could become a silent killer. Minerals would calcify into "scales," and oxygen would eat away at the metal, causing internal rust and clogs. The Intervention

The facility’s maintenance lead, Elias, knew that raw water wasn't enough. He introduced NALCO 93033

—a heavy-duty chemical treatment designed specifically for these high-performance cooling circuits. Unlike standard cleaning agents, 93033 wasn't just a soap; it was a protective shield.

Elias used a graduated beaker to carefully measure out the precise milliliters required for each laser's water volume. As the additive blended with the coolant, it formed a microscopic, non-stick barrier on the internal pipes. The Result

Months passed, and while neighboring factories struggled with downtime and "boiling" systems, Elias’s lasers remained cool and efficient. By maintaining the chemical balance, the NALCO treatment: Prevented Corrosion:

Stopping rust before it could compromise the fragile laser optics. Controlled Scaling:

Ensuring that heat transfer remained at peak efficiency without mineral blockages. Guaranteed Uptime:

Eliminating the need for emergency shutdowns due to cooling failures.

In the world of heavy industry, NALCO 93033 was the invisible guardian, ensuring that the plant’s "pulse" never skipped a beat. or more technical storage guidelines for this chemical?

NALCO 93033 Cooling Additive Guide | PDF | Shelf Life - Scribd

Nalco 93033 (currently marketed under the Ecolab brand following the merger) is a high-performance oxygen scavenger and corrosion inhibitor used primarily in industrial boiler water treatment.

Because this is an industrial chemical, the following guide focuses on its technical application, function, and safety protocols for professionals in the water treatment industry.

What is Nalco 93033?

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.

Unlike traditional formulations that rely heavily on heavy metals like chromate or zinc (which pose environmental disposal issues), Nalco 93033 employs a synergistic blend of:

The unique formulation allows for operation at higher cycles of concentration (COC), meaning less blowdown, reduced water consumption, and lower overall operational costs.

Environmental and Regulatory Compliance

Nalco 93033 does not contain heavy metals (no chromium, no lead). The phosphate content, while a nutrient for algae in natural waters, is typically below discharge limits when blowdown is properly managed.

Always consult your local wastewater treatment authority regarding phosphate discharge limits. You may need to remove phosphates via precipitation (lime) if limits are stringent (<1 mg/L PO₄).

How It Works in Practice

When injected into cooling tower water, Nalco 93033 performs three simultaneous actions:

  1. Threshold Inhibition: The polymer components interfere with crystal lattice formation of calcium carbonate, meaning scale particles cannot adhere to heat transfer surfaces. Even at low concentrations (a few ppm), the product raises the "threshold" of saturation before precipitation occurs.
  2. Passivation: Orthophosphate reacts with iron to form a thin, adherent layer of ferric phosphate, which blocks anodic sites and reduces general corrosion rates to below 1–2 mils per year (MPY)—the industry standard.
  3. Chelation: Minor chelating agents bind to metal ions like iron and manganese, preventing them from depositing as sludge or catalyzing under-deposit corrosion.

Metals Compatibility

Problem: Red rust (iron oxide) deposits

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.
