Nu-Calgon 7537-05 Ty-Ion B20

Ty-Ion B20 is a liquid nitrite-borax corrosion inhibitor and dispersant for closed recirculating systems. It combines corrosion inhibitors, including a copper corrosion inhibitor, a unique copolymer dispersant, and a color indicator into a complete treatment for both hot and chilled water closed systems containing ferrous and nonferrous metal components. The color indicator facilitates leak detection and proper treatment residuals.
Ty-Ion B20 controls corrosion by producing a protective passivating film on all exposed metal surfaces through a synergistic combination of sodium nitrite and borax, plus organic inhibitors. In addition, its copolymer dispersant inhibits deposit formation through its dispersing capability.
The unique color indicator in Ty-Ion B20 is extremely useful in locating any existing leaks in closed systems, to quickly determine if the systems are properly treated and also to determine if the pH has dropped in the system because of bacterial infestation.
