Cooling water treatment specified corrosion inhibitior for multi-metal containng cooling systems to operate at high or low temperatures.
Alkaline Corrosion Inhibitor blend for multi-metal protection in closed-loop and chilled cooling water CLOSED circulating system
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.
