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.
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. nalco 93033
A midwestern US coal-fired power plant was experiencing chronic scaling on its main condenser, leading to a 4-inch Hg backpressure increase. The plant was using a low-cost zinc-based program but saw tube fouling every 6 months.
After switching to Nalco 93033 at a feed rate of 60 ppm product, with a maintained orthophosphate residual of 6 mg/L and pH 7.8:
ROI: System paid for itself in 5 months via fuel savings and reduced maintenance labor. According to the Safety Data Sheet (SDS) for
Nalco 93033 is sold through authorized Nalco Water distributors and direct via Ecolab’s industrial channel. Pricing is typically $4 – $8 per pound depending on volume and contract terms. It is available in:
NSN (NATO Stock Number) availability: Nalco 93033 is not commonly stocked under NSN, but Nalco provides cross-references for military-grade cooling systems upon request.
Dissolved oxygen in boiler feedwater is one of the primary causes of corrosion in steam systems. When oxygen reacts with the metal surfaces of the boiler or feed lines, it forms oxides (rust), which leads to pitting and eventual system failure. Storage: Store in original sealed containers between 40°F
Nalco 93033 works by chemically reacting with dissolved oxygen to form neutral compounds (such as water, nitrogen, and carbon dioxide), effectively "scavenging" the oxygen before it can attack the metal.
The Reaction: Unlike some older inorganic scavengers (like sodium sulfite), organic scavengers like Nalco 93033 do not contribute dissolved solids (TDS) to the boiler water. This is crucial for high-pressure systems where maintaining low TDS is necessary for steam purity.
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.
