Manufacturers, Exporters and Suppliers of Hot Water Corrosion Inhibitors – Protection for Closed Loop & Industrial Heating Systems in Delhi

Innova Corporate (India) offers Hot Water Corrosion Inhibitors for closed-loop hot water heating systems, solar water heaters, and process hot water circuits in Delhi's hotels, hospitals, data centers, commercial buildings, and industrial plants (textile, pharma, food). Delhi's make-up water – Yamuna river water (TDS 800-1500 mg/L, chlorides 150-300 ppm) or groundwater (TDS 1500-3500 mg/L, chlorides 200-500 ppm, high iron) – causes general and pitting corrosion of mild steel and copper when heated to 60-90°C (140-194°F). Our inhibitors are based on sodium nitrite (anodic inhibitor), molybdate (pitting inhibitor), tolyltriazole (copper corrosion inhibitor), and a pH buffer (borate or bicarbonate). For Delhi's large data centers (hot water loops for waste heat recovery) and pharmaceutical plants (hot water for CIP), we recommend a nitrite-borate-azole blend at 500-1000 ppm (as product). For solar water heaters (increasingly popular in Delhi), our propylene glycol-based antifreeze + inhibitor prevents corrosion and scaling (also protects against freezing – Delhi's winter 0-5°C/32-41°F). For process hot water circuits in textile and food processing, we offer a higher temperature stable (up to 120°C/248°F) inhibitor containing phosphonates and azoles. The products are supplied as liquid concentrates (25-40% active). We provide test kits for nitrite (colorimetric), molybdate (thiocyanate method), pH, and azole (UV) to monitor treatment levels. For existing systems with rust or scale (common in older Delhi buildings), we offer a pre-treatment cleaner (acidic or alkaline) before inhibitor application. For food-grade hot water circuits (dairy, bakeries), we supply NSF-approved inhibitors (molybdate-based, no nitrite). Available in 25L, 200L drums. Technical support includes system volume calculation, dosing recommendations, and annual maintenance checks.

Hot Water Corrosion Inhibitor can also be used in low pressure steam boilers as a single drum programme in Delhi, where it is specially designed for waters with a high non-alkaline hardness and low silica levels. It is highly suitable for ferrous and cuprous materials found in local processing equipment. While it may be used with care in systems containing galvanized steel, it is unsuitable for systems containing aluminium.
