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

Innova Corporate (India) offers Chilled Water & Closed Loop Corrosion Inhibitors for Dehradun's air conditioning systems, process chillers, and closed recirculating loops in pharmaceutical plant cleanrooms, paper mill control rooms, hospitals (Army Hospital, Doon Hospital), hotels, and educational institutions (FRI, IMA, IIT Roorkee). Dehradun's make-up water – groundwater (hardness 200-500 ppm, chlorides 100-200 ppm) or surface water (hardness 100-250 ppm, chlorides 30-80 ppm) – can cause pitting corrosion of mild steel, copper, and brass in chilled water systems. Our inhibitors are based on molybdate (100-200 ppm), nitrite (400-800 ppm), or azole (tolyltriazole), often blended with phosphate and polymer dispersants. For Dehradun's large pharmaceutical plants (Selaqui) and paper mills, we recommend nitrite-borate-azole formulation for mixed metallurgy systems. For hospitals and hotels, we offer easy-to-use liquid inhibitors with tracer dye. For food-grade closed loops (dairy, bakeries), we supply NSF-certified inhibitors (molybdate-based, no nitrite). We provide corrosion coupon testing (ASTM D2688), test kits (nitrite, molybdate, pH, conductivity, azole), and automatic feed systems. For systems with high iron content (common in Dehradun's groundwater), our inhibitors include additional chelants. Available in 25L, 200L drums, and 1000L IBCs.
