Boiler Corrosion Inhibitor

What is boiler corrosion inhibitor?

Boiler corrosion inhibitor is a closed-water treatment chemical that lessens the corrosion rate of boiler metals or alloys. Product is either clear or dyed.

How does boiler corrosion inhibitor protect boilers?

Boiler corrosion inhibitor protects boilers through passivation, or the formation of a thin film on the surface of a material. It inhibits contact of the corrosive substance, thus preventing either oxidation or reduction.

When boiler is already corroding, is it alright to apply a corrosion inhibitor?

Yes. Corrosion inhibitor works through either adsorption or scavenging. Adsorption is molecular adhesion of a chemical on the metal surface while scavenging is the inactivation of dissolved oxygen.

What are the active ingredients of boiler corrosion inhibitor?

Boiler corrosion inhibitor is a combination of nitrite, borate, silicate, and alkaline solution formulated to minimize corrosion and deposition. Sodium nitrite is a good metal passivator while the alkaline assists in increasing the system’s pH.

How do you apply boiler corrosion inhibitor into the water system?

Just add the product into your system until water turns into a light pink color. Product does not require testing.

Is boiler corrosion inhibitor compatible to different boiler types?

Yes. Product is perfect for hot water boilers, low make-up boilers, industrial boilers, commercial boilers, and outdoor residential wood boilers.

How much is the treatment capacity of boiler corrosion inhibitor for every gallon of water?

For detailed information, consult the material safety data sheet (MSDS). 

Corrosion Inhibitor
