Scale cleaning chemicals GREEN EX 980
PRODUCT CODE:GREEN EX 980Price: ContactGREEN EX 980 is a chemical for boiler water treatment, which may inhibit both corrosion and scale formation with one single composite formulation. The corrosion inhibitor contained in this chemical is TANNIC ACID, which is a safe substance compared with others such as hydrazine. Excellent dispersant is also contained, which effectively inhibits scale formation and disperses calcium or ferric oxide sludges.

- Excellent corrosion inhibition inside the boiler
TANNIC ACID effectively inhibits corrosion inside the boiler by the following three functions:
- Oxygen removal
- Formation of insoluble films with iron
- Formation of passive films
- Excellent dispersion
The dispersant contained in this chemical effectively inhibits scale or deposit formation, which consequently prevents secondary corrosion occurring under the deposit.
- Energy is saved
As tannic acid do not produce any soluble solid, electric conductivity of boiler water do not increase like sodium sulfite. As a result, the blowdown rate is reduced, together with the amount of heat loss.
- Safety is improved
Safety of the chemical is improved, as TANNIC ACID is contained , which is a natural compound known as constituent of tea.
- Steam purity is improved
Steam would be pure when GREEN EX980 is applied, as no volatile constituent is contained.
