Manufacturers, Exporters and Suppliers of Chilled Water & Closed Loop Corrosion Inhibitor – Rust Protection for HVAC & Recirculating Systems in Agra

Chilled Water & Closed Loop Corrosion Inhibitors from Innova Corporate are specifically formulated for Agra's air conditioning systems, process chillers, and closed recirculating loops found in hotels (over 200 near Taj Mahal), shopping malls, hospitals, and industrial HVAC systems. Closed loops have minimal water loss, leading to accumulation of corrosive ions over time. Agra's make-up water (Yamuna or borewell) contains chlorides (150-300 ppm), sulfates (200-500 ppm), and dissolved oxygen that cause pitting corrosion of mild steel, copper, and brass components. Our corrosion inhibitors are based on molybdate (100-200 ppm as MoO₄²⁻), nitrite (400-800 ppm as NO₂⁻), or azole (benzotriazole/tolyltriazole for yellow metals) technologies, often blended with phosphate and polymer dispersants. For Agra's large hotel central plants (500-2000 TR capacity), we recommend nitrite-borate-azole formulations that provide excellent protection for mixed metallurgy systems (steel pipes, copper coils, brass valves). The inhibitors work by forming a protective passive layer on metal surfaces. They also contain buffering agents to maintain pH between 8.5-10.5 (ideal for closed loops). Our products are free of heavy metals (no chromium) and meet environmental discharge limits. For smaller chiller systems (e.g., in Agra's textile units or hospitals), we offer easy-to-use liquid inhibitors with built-in dye tracer for leak detection. Annual maintenance includes system cleaning (using our closed loop cleaners) and inhibitor recharge. We supply test kits for nitrite, molybdate, pH, and conductivity for on-site monitoring. Properly treated closed loops in Agra can operate for 10+ years without corrosion failures.
