NALCO 93033 is a liquid oxidizing biocide primarily used for chemical water treatment in industrial cooling systems and boilers. Key Uses and Applications Cooling Systems:
It acts as a disinfectant to ensure the long-term proper functioning of cooling water circuits in machines and lasers. Boilers and Steam Lines:
It is used to treat systems where the water or steam does not come into contact with edible products in food processing areas. NSF Category G7: The product is registered under the NSF White Book
for use in and around food processing areas, provided there is no direct contact with food. Physical Properties and Handling Appearance: Typically a clear, colorless to light green-yellow liquid. Composition: Often contains chlorine-based oxidizing agents. Shelf Life:
It has a shelf life of approximately one year when stored at a maximum temperature of 25°C.
It is considered toxic to aquatic organisms and is generally non-flammable. Standard safety protocols require the use of goggles and face shields during handling due to potential skin and eye irritation.

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.
According to the Safety Data Sheet (SDS) for Nalco 93033 (which you should always obtain before use):
Personal Protective Equipment (PPE):
Wear chemical-resistant gloves (nitrile or neoprene), safety goggles with side shields, and an apron. In case of splashing, use a face shield. Safety, Handling, and Storage According to the Safety
First aid measures:
Storage: Store in original sealed containers between 40°F and 100°F (4°C – 38°C). Protect from freezing; if frozen, thaw slowly at room temperature and agitate before use. Shelf life is typically 12–18 months.
To understand why Nalco 93033 is effective, you must understand the three enemies of a cooling system.
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.
The most common application. Nalco 93033 is designed for systems with recirculation rates between 1,000 and 500,000 gallons. It protects carbon steel, copper, and admiralty brass against pitting and galvanic corrosion.
