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

Chilled Water & Closed Loop Corrosion Inhibitors from Innova Corporate are specifically formulated for Ahmedabad's air conditioning systems, process chillers, and closed recirculating loops found in hotels (SG Highway, Ashram Road, Prahlad Nagar), shopping malls (Ahmedabad One, Himalaya Mall), hospitals (Civil, Sterling, Apollo), corporate offices (GIFT City, Bodakdev, Satellite), and industrial HVAC systems (textile mills, pharmaceutical cleanrooms, dairy cold storage). Closed loops have minimal water loss (typically <1% per month), leading to accumulation of corrosive ions (chlorides, sulfates, dissolved oxygen) over time. Ahmedabad's make-up water – a blend of Narmada canal water and groundwater – contains chlorides (150-400 ppm), sulfates (200-600 ppm), and high TDS (800-2000 ppm), which cause pitting corrosion of mild steel, copper, and brass components in chillers, heat exchangers, and piping. Our corrosion inhibitors are based on molybdate (100-200 ppm as MoO₄²⁻), nitrite (400-800 ppm as NO₂⁻), or azole (benzotriazole – BZT, or tolyltriazole – TTZ for yellow metals) technologies, often blended with phosphate and polymer dispersants. For Ahmedabad's large hotel central plants (500-2000 TR capacity), 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 (gamma-Fe₂O₃ or Fe₃O₄) on metal surfaces and by blocking cathodic sites. They also contain buffering agents (borate, bicarbonate, or phosphate) to maintain pH between 8.5-10.5 (ideal for closed loops). Our products are free of heavy metals (no chromium, no lead) and meet GPCB discharge limits for the occasional blowdown. For smaller chiller systems (e.g., in Ahmedabad's textile units or hospitals), we offer easy-to-use liquid inhibitors with built-in dye tracer (fluorescein or rhodamine) for leak detection and concentration monitoring. For food-grade closed loops (e.g., chillers for dairy processing, beverage cooling), we supply NSF/ANSI Standard 60 certified inhibitors (usually molybdate-based, with no nitrite or azole). Annual maintenance includes system cleaning (using our closed loop cleaners – alkaline and acidic) to remove existing corrosion products and biofilms, followed by inhibitor recharge. We supply complete test kits for nitrite (DPD or ferrous ammonium sulfate), molybdate (thiocyanate colorimetric), pH (electrode or strips), conductivity, and azole (UV absorbance at 256 nm). For automated control, we offer injection systems with conductivity-based blowdown and nitrite/molybdate sensors. Properly treated closed loops in Ahmedabad can operate for 10-15 years without corrosion failures, whereas untreated systems often develop leaks within 2-3 years. Available in 25L, 200L drums, and 1000L IBCs.
