Corrosion in general terminology is the destructive attack of metal. Metal loss or damage can occur due to chemical & electrochemical reaction, physical erosion or biological attack. Corrosion is always because of chemical reaction. Water corrosiveness is determined by the impurities present in it. Oxygen, dissolved solids, gases and acids in water attack the common construction material.

Major Problems due to Corrosion:-

Metal loss (capital loss)
System leakage or burst
Water / Fluid contamination
Poor heat transfer (power loss)
Corrosions are of various types and differ with application to application.

Major Types of Boiler Corrosion:-

Uniform/General Corrosion due to high temperature
Pitting Corrosion due to high temperature and chloride
Galvanic Corrosion due to multi-metals
Oxidation Corrosion due to oxygen and carbon dioxide
Stress Cracking Corrosion due to high pressure and temp.

Boiler Scale & Corrosion Inhibitor

Chemtex’s Boiler Scale and Corrosion Inhibitors are a unique formulation of catalyzed oxygen scavenger and super threshold antiscalant to provide designed for boiler water treatment used in coil type boilers. The antiscalant inhibits deposition of calcium and iron scales on coils.

Equivalent or even better than Maxtreat 3220

Properties	Unit	Typical Value
Form and Appearance	-	Clear Viscous Liquid
pH (neat)	pH	Mildly Alkaline
Solubility	-	Freely Soluble in Water

Dosage and Method:-

Chemtex’s Boiler Scale and Corrosion Inhibitors are dosed continuously to the feed water line, depending upon the feed water temperature and type of boiler system. It is dosed exactly as per the dosage rate and method of MAXTREAT 3220.

Please refer to your CSL service engineer for exact product dosage.

Key Features & Benefits:-

Catalyzed Oxygen Scavenger for instant oxygen removal
Minimizes or eliminates oxidation corrosion (corrosion due to presence of oxygen)
Volatile product that does not add to the TDS level and hence minimizes scaling
Prevents scaling and thus overheating of coil
Imparts power saving
