USCS 662 - All In One Boiler Scale & Corrosion Inhibitor

Sodium Sulfite (Na2SO3), Polymer, Amine

This is a complete product for the treatment of small to medium-sized boilers. It delivers sulfite for oxygen removal, a boiler internal treatment polymer to maintain clean boiler surfaces, and an amine for condensate system protection. It is particularly well-suited for boilers with consistent soft-water makeup.

• Feed product to the feed tank or deaerator storage section.
• Test with the sulfite test kit. Feed at a rate to achieve a residual level in the boiler of 20-60 ppm (20-50 ppm optimum) as SO3, not as Na2SO3. Use the titration reagent for 6ppm/ drop as SO3.
