Description :::
Nitrite based Corrosion Inhibitor for Water and Glycol Brine system is a multimetal corrosion inhibitor based on nitrate and other organic compounds with special yellow metal corrosion inhibitor and antiscaling chemical that helps to prevent scale deposition or also removes adhering loose scale deposits from the heat transfer fluid system.
The disadvantages of not treating the closed circuit water can be equally troubling for the system operator:-
1. Leakage in PHE and AHU due to corrosion
2. Plugging and clogging of tubes and reduced flow rate
3. REduced heat transfer
4. Need of regular descaling that incurs shutdowns, loss of labour and time
5. Fouling of brine of chilled water
Chemical treatment removes dissolved oxygen that causes oxidation of metal to metal oxide i.e., Iron + Oxygen = Iron Oxide (Rust)
The chemical also contains a specific inhibitor to protect the copper from corrosion and removes/prevents any sort of scale formation in the system.
Application :::
Engine Jacket Cooling or heating system, Chiller Water Circuit, Glycol Brine System, Hot Water or steam Circuit, Engine Coolant, Process chilling and heating system etc.
DOSAGE :::
Nitrite base Corrosion Inhibitor for Water and Glycol Brine is normally fed continuously to the re-circulating closed system by injection dosing pump of dosed to the expansion tank. The amount of Nitrite base Corrosion Inhibitor for Water and Glycol Brine required inhibiting corrosion depends on the type of system and plant operating conditions. The specific dosage rates can be specified by the testing and given parameter.

Benefit :::
Zero or negligible loss of metal or corrosion Excellent heat transferability and flow rate No need of descaling closed circuit equipment Long and extended life of Water without fouling.
TREATMENT Feature
Sodium Nitrate Iron and Steel corrosion inhibitor. 800-2500 ppm recommended.
Molybdate Slows the growth of bacteria.
Tolyltriazole Copper corrosion Inhibitor.
Synthetic polymer Prevents hard scale built up.
Borax buffer Corrects the water pH (Maintain pH level between 8.5 to 9.2).
Silicates A common corrosion inhibitor used by automotive antifreeze suppliers is silicates. Silicates have the disadvantage of building up an insulating layer on components and are not recommended for industrial engines. Concentration should not exceed 25 ppm.
