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

Innova Corporate (India) offers Chilled Water & Closed Loop Corrosion Inhibitors for Amritsar's air conditioning systems, process chillers, and closed recirculating loops found in hotels (near Golden Temple, Ranjit Avenue), hospitals (Civil Hospital, private clinics), shopping malls (AlphaOne, Celebration Mall), and industrial HVAC systems (tanneries, textile mills, food processing units). Amritsar's make-up water – a mix of Ravi river water (hardness 400-700 ppm, chlorides 150-300 ppm) and groundwater (hardness 500-800 ppm, chlorides 200-400 ppm) – contains high chlorides and sulfates that cause pitting corrosion of mild steel, copper, and brass components in chillers, heat exchangers, and piping. Our inhibitors are based on molybdate (100-200 ppm as MoO₄²⁻), nitrite (400-800 ppm as NO₂⁻), or azole (tolyltriazole – TTZ for yellow metals), often blended with phosphate and polymer dispersants. For Amritsar's large hotel central plants (200-1000 TR capacity) near Golden Temple, we recommend a nitrite-borate-azole formulation that provides excellent protection for mixed metallurgy systems (mild steel pipes, copper coils, brass valves, stainless steel plates). The inhibitors work by forming a protective passive layer (γ-Fe₂O₃ or Fe₃O₄) and blocking cathodic sites. They also contain buffering agents (borate, bicarbonate) to maintain pH 8.5-10.5. Our products are free of heavy metals (no chromium, no lead) and meet PPCB discharge limits. For smaller chiller systems (e.g., in Amritsar's textile units or small hotels), we offer easy-to-use liquid inhibitors with built-in dye tracer (fluorescein) for leak detection. For food-grade closed loops (e.g., chillers for dairy processing, food plants), we supply NSF/ANSI Standard 60 certified inhibitors (molybdate-based, no nitrite). Annual maintenance includes system cleaning (using our closed loop cleaners) followed by inhibitor recharge. We supply complete test kits for nitrite (DPD method), molybdate (thiocyanate), pH, conductivity, and azole (UV). For automated control, we offer injection systems with conductivity-based blowdown. Properly treated closed loops in Amritsar can operate for 10-15 years without corrosion failures. Available in 25L, 200L drums, and 1000L IBCs.
