Scale & Corrosion Inhibitor Supplier India | Cooling Tower Chemical

Scale and corrosion inhibitor blend from Drashti Chemicals protects cooling tower circuits, closed-loop chillers, and boiler feed systems across Gujarat's hard-water zones. Untreated systems scale calcium carbonate on heat exchanger tubes within months and corrode carbon steel at oxygen concentration cells — inhibitor program costs a fraction of tube replacement and production downtime.

Phosphonate + polymer blend for open cooling towers (handles CaCO₃, CaSO₄, and silica at 3–5 cycles of concentration). Nitrite-based for closed chilled-water loops (corrosion-only, no scale). Morpholine/hydrazine-free blend for boiler feed when oxygen scavenger integration required. Provide makeup water analysis — Drashti selects program. COA confirms active phosphonate and polymer content.

Cooling tower dose: 50–150 mg/L in circulating water; bleed-off controls concentration — inhibitor supplements lost in blowdown. Closed loop: 1000–3000 mg/L nitrite residual maintained. Test kits for orthophosphate or nitrite weekly — dose pump calibration monthly. Over-inhibition is rare; under-inhibition shows as white scale on tube sheet within 4–6 weeks.

Packaging: 20 kg carboys, 200 kg drums, 1000 kg IBC. MOQ one carboy for water-treatment contractor trial; bulk quote on request for plant-wide programs. MSDS and COA per batch. GST 24AGLPC6288M1ZX. Drashti Vadodara provides dosing schedule template with first order.

Combined inhibitor vs. separate antiscalant and biocide: inhibitor handles scale and mild corrosion; biocide is separate necessity for Legionella control in cooling towers. Inhibitor vs. acid feed for scale: acid lowers pH and LSI but corrodes; inhibitor is non-acid approach. For RO, use dedicated RO antiscalant — cooling tower inhibitor is wrong chemistry for membrane.
