AFCO 9007 is a blend of high-performance corrosion and scale inhibitors designed for highly stressed conditions. It can be used without acid in highly alkaline waters and is more chlorine and high temperature stable than traditional phosphonate blends. AFCO 9007 employs state of the art polymer technology designed to keep heat transfer surfaces free from mineral deposits. This formula contains an inert fluorescent dye tracing ingredient for accurate control/monitoring.
