Types of Corrosion Inhibitors

Corrosion Inhibitors are used in both open & closed recirculating cooling water treatment products. Benzotriazole (BZT) is a similar, but less common inhibitor. Sodium Molybdate is also used in cooling water treatment as a corrosion inhibitor. Molybdenum is used both as an inhibitor and as a trace chemical to monitor dosage measurements due to its yellow color.

Sodium Nitrite is another common metal corrosion inhibitor for iron & steel and is typically used in closed-loop cooling water treatment products, such as chiller systems. (Other allied products which accompany these products are borates which act as buffers/stabilizers and have general cleaning attributes as well.)
