Corrosion Inhibitor for Multi Metal Cooling Water
Corrosion Inhibitor Additives for Water system ::: Alkaline Corrosion Inhibitor blend for multi-metal protection in closed-loop and chilled cooling water CLOSED circulating system.
This is a Highly effective INHIBITOR for closed loop , line chilled water with unique dual control of corrosion and scale from system.
This closed water treatment chemicals are designed to treat hot and chilled water systems. The product contains a combination of molybdate, borate, and silicate formulated to minimize corrosion and deposition. The product comes in a clear and also a variant pink appearance form.
RXSOL-40-4011-020 is a superior multifunctional, molybdate-based chemical treatment used for the control of corrosion in closed cooling systems and chilled water systems. RXSOL-40-4011-020 is a liquid product containing a combination of ferrous and non-ferrous corrosion inhibitors, a non-carbonate buffer, scale inhibitors, dispersants and a leak detection dye.
Keep in a tightly closed container in storage closed area . Recommended storage temperature is 500C
◦Very effective to Controls corrosion on brass, aluminum, steel, and stainless steel
◦Extends equipment life & Improves overall equipment efficiency
Cooling water treatment specified corrosion inhibitior for multi-metal containng cooling systems to operate at high or low temperatures
For systems containing no aluminium, RXSOL-40-4011-020 should be dosed at 0.5 to 1% (5 L–10 L/ 1000 L) in order to give a reserve of 50 ppm of sodium molybdate. For systems containing aluminium, the dosage of 1–1.5% should be added in order to maintain a minimum reserve of 100 ppm of sodium molybdate. In certain circumstances it may be necessary to adjust the pH separately by the addition of pH CONDITIONER - your Consultant will advise. In systems requiring significant passivation/higher initial dosages may be required to yield the required inhibitor residual.
Normal treated water control limits
pH 7.0 - 9.0 (Without Aluminium)
pH 7.0 - 8.0 (With Aluminium)
For systems containing aluminium it is important to maintain the system water pH in the range 7.0 - 8.0. Occasionally depending on the water characteristics and system treatment history the pH may rise above pH 8.0 which means that the risk of aluminium corrosion is increased - if this happens then high pH can be reduced by adding an appropriate quantity of pH Conditioner.
How to Maximize efficiency of Cooling Tower / Chiller Systems
- Control Scale Formation: Maintain proper water chemistry and use an effective scale inhibitor to prevent calcium, magnesium and silica deposits on heat-transfer surfaces.
- Prevent Corrosion: Maintain pH within the recommended operating range and use suitable corrosion inhibitors to protect carbon steel, copper and other system metals.
- Control Microbiological Growth: Maintain an effective biocide program to control bacteria, algae, fungi and biofilm that can reduce heat transfer and restrict water flow.
- Optimize Cycles of Concentration: Monitor conductivity/TDS and control blowdown to maximize water efficiency without allowing excessive dissolved solids or scaling.
- Keep Heat-Transfer Surfaces Clean: Regularly inspect and clean condenser tubes, evaporators, cooling-tower fill and strainers. Even relatively thin deposits can reduce heat-transfer efficiency.
- Monitor Chilled & Condenser Water: Routinely check pH, conductivity, hardness, alkalinity, chlorides and inhibitor residuals; investigate abnormal trends before they develop into major problems.
- Maintain Proper Water Flow: Inspect pumps, strainers, nozzles, valves and cooling-tower distribution systems to ensure uniform flow and avoid low-flow areas, fouling and poor heat transfer.
- Inspect & Clean Regularly: Schedule periodic cleaning, descaling and system inspection based on operating conditions and water-quality trends rather than waiting for a noticeable loss of performance.
- Track System Performance: Log temperatures, pressures, approach temperature, conductivity, chemical residuals, make-up and blowdown. Trending these values helps identify fouling and efficiency losses early.
- Protect During Shutdown: For seasonal or standby systems, drain or preserve equipment correctly and maintain appropriate corrosion and microbiological protection during extended shutdown periods.
