is a specialty chemical from Ecolab’s Nalco Water division. It’s typically a cooling water treatment formulation —often a scale and corrosion inhibitor blended with dispersants and sometimes azole-based copper protection. The "3D" prefix generally indicates a third-generation, high-performance chemistry designed for open recirculating cooling systems, particularly where strict environmental or operational constraints exist (low-zinc, high-silica waters, or heat exchanger sensitivity).
If you are currently using a competitor’s product (Suez, ChemTreat, Veolia, etc.), Nalco is highly motivated to convert you. Industrial chemical suppliers frequently offer to prove performance superiority. They will even send a technician to manage the transition.
According to official Safety Data Sheets (SDS), the product has the following physical characteristics: Appearance: Viscous liquid, typically clear to light yellow or orange. pH (Neat): 2.4 – 3.8, indicating it is mildly acidic. Solubility: Completely soluble in water. Approximately 1.22 g/cm³ at 25°C. Freezing Point: -7.6°C (18.32°F). Application & Technology 3DT394 is designed to work with Nalco’s 3D TRASAR™ Technology
Regulatory bodies like the EPA (USA) and REACH (EU) are cracking down on phosphorus discharge. If your facility operates near a river, lake, or protected wetland, using a phosphate-free product like 3DT394 .
The primary active components of Nalco 3DT394 are . These are classified as polymeric dispersants , which have a high affinity for particulate matter. The product is completely soluble in water and has a low pH of 2.4 to 3.8. Its ability to remain stable under normal conditions means it can maintain its integrity in the harsh environment of a cooling tower's recirculating water.
From a health and safety perspective, Nalco 3DT394 is notable for its low toxicity profile. Under normal use conditions, no adverse health effects are known or expected via eye contact, skin contact, ingestion, or inhalation. The product is also not regulated for transport by land, air, or sea, simplifying logistics for industrial users.
Typically 12 to 18 months from date of manufacture when stored in a sealed container between 40°F and 100°F. Keep free from freezing.
to maintain the exact level needed to protect your copper heat exchangers. Why Focus on Yellow Metals?
: Wear safety glasses and protective gloves when handling the concentrate.
The term "free" is often a shorthand used in engineering forums and spec sheets. Nalco 3DT394 is explicitly formulated to be:
When plant managers or safety officers search for "Nalco 3DT394 free," they are often trying to locate free downloads of essential regulatory compliance documents. Safety Data Sheets (SDS)
The product is a clear, light yellow to orange viscous liquid with a mild odor. Its physical properties include:
Legacy treatments required PPE-level safety gear for handling due to zinc or chromate content. Because 3DT394 is non-toxic for industrial handling (refer to SDS for specifics, but it lacks heavy metals), it .
: Wear safety glasses and protective gloves when handling. Suitable clothing should be worn to prevent prolonged skin contact. First Aid : Inhalation : Get medical attention if symptoms occur. Skin/Eye Contact : Rinse immediately with plenty of water. Ingestion : Rinse mouth; treat symptomatically.
, its role in modern water treatment, and how organizations can find and technical documentation for this product. What is Nalco 3DT394? 3D TRASAR™ 3DT394 Go to product viewer dialog for this item.
Because SDS documents are mandated by law, many universities and public safety departments maintain public archives of common industrial chemicals.
