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

Innova Corporate (India) offers Closed System Treatment 302 – an advanced multi-metal corrosion inhibitor for larger or more critical closed loops in Amritsar'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/brass), and an organic polymer dispersant (polyacrylate). It provides superior protection for mixed metallurgy systems (mild steel, copper, admiralty brass, stainless steel 304/316) commonly found in Amritsar's large hotels (Golden Temple area, Ranjit Avenue), shopping malls, hospitals, textile process chillers, and food processing refrigeration. Unlike basic nitrite-only treatments (Formula 0), Formula 302 offers high 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 and during system shutdowns/lay-ups. For Amritsar's facilities that operate seasonally (e.g., hotels with reduced occupancy in summer peak heat or during off-season), this is critical to prevent under-deposit corrosion. 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), 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: Amritsar's 800 TR hotel chiller loop treated with 302 showed zero corrosion (<0.1 mpy) after 3 years (vs. 0.5 mm/year previously). The product is non-foaming and compatible with glycol antifreeze (ethylene or propylene glycol) at concentrations up to 30% – useful for systems exposed to freezing (Amritsar's winter occasionally drops below freezing). For closed loops with aluminum components (e.g., some automotive heat exchangers), we have a special variant without nitrite (nitrite accelerates aluminum corrosion). Available in 200L drums and 1000L IBCs. We provide complete monitoring kits (molybdate, nitrite, pH, conductivity, azole). For annual maintenance, we offer system cleaning (removal of corrosion products) followed by fresh inhibitor charge.
