Manufacturers, Exporters and Suppliers of INNOVA CW 302 – Advanced Closed System Treatment for Corrosion & Deposit Control in Bihar

Innova Corporate (India) offers Closed System Treatment 302 – an advanced, multi-metal corrosion inhibitor specifically designed for larger or more critical closed loops in Bihar's industrial and commercial facilities. This formulation contains a synergistic blend of molybdate (100-200 ppm), nitrite (300-500 ppm), tolyltriazole (TTZ, 2-5 ppm for copper and brass), and an organic polymer dispersant (polyacrylate, 5-15 ppm). It provides superior protection for mixed metallurgy systems (mild steel, copper, admiralty brass, stainless steel 304/316) commonly found in Bihar's large sugar mills (central HVAC for offices and labs), pharmaceutical plants (cleanroom chillers), and commercial buildings (hotels in Patna, Bodh Gaya, hospitals). Unlike basic nitrite-only treatments (Formula 0), Formula 302 offers higher temperature stability (up to 95°C/203°F), making it suitable for closed hot water heating systems as well as chilled water. The molybdate component acts as an anodic film former that is less oxygen-dependent than nitrite, ensuring protection even in stagnant zones, dead legs, and during system shutdowns/lay-ups. For Bihar's industries that have seasonal shutdowns (e.g., sugar mills after crushing season, some rice mills), this is critical to prevent under-deposit corrosion and pitting. The product also contains a buffer (borate or phosphate) to maintain pH 9-10.5. Dosage: initial charge 3-5% by volume (1500-2500 ppm product concentration), then maintain molybdate at 100-150 ppm (measured via colorimetric test) and nitrite at 300-600 ppm. For large systems (>50 m³ volume), we recommend automatic feed systems with online molybdate and pH sensors. Case example: A Patna hotel's 600 TR chiller loop (serving guest rooms and banquet halls) treated with 302 showed zero corrosion (<0.1 mpy) after 3 years (vs. 0.4 mm/year previously, with leaks every 2 years). The product is non-foaming and compatible with glycol antifreeze (ethylene or propylene glycol) at concentrations up to 30% – important for systems that may be exposed to freezing (Bihar's winter occasionally touches 5°C/41°F, but glycol is rare). For closed loops with aluminum components (e.g., some automotive heat exchangers in small engineering workshops), we have a special variant without nitrite (nitrite accelerates aluminum corrosion). Available in 200L drums and 1000L IBCs. We provide complete monitoring kits for molybdate (thiocyanate method), nitrite (sulfanilic acid method), pH, conductivity, and azole (UV absorption). For annual maintenance, we offer system cleaning (removal of corrosion products using our alkaline/acid cleaners) followed by fresh inhibitor charge.
