FINEAMIN ®
Characteristics
▐ Affects the structure of the protective magnetite layer in the boiler so to increase protection ▐ Reduction of boiler water blow-down rate ▐ The system is protected against corrosion through protective polyamines ▐ Dispersion of sediments, gratings, dirt, mineral salts and iron oxide ▐ Energy-saving thanks the improved heat transfer ▐ The salt content in the system is not increased decline of the blow-down rate ▐ Alkalises the entire steam system including condensate recirculation and feed water system ▐ Hardness stabilization and protection against new sediments

Advantages
▐ Water and Energy Savings : reduction of the blow-down rate ▐ ▐ Efficient, because
FINEAMIN ®
avoids any kind of corrosion, your Capital Plant is protected Protects with a monomolecular protective layer all parts of the plant ▐ Scale and deposit inhibition , online dispersing action of old deposits ▐ ▐ Avoids and controlles magnetite growth and magnetite sludges Easy to use :
FINEAMIN ®
is injected in 99% of the plants with only one dosing station ▐ ▐ ▐ Economic: low dosing rate and very low maintenance costs Environmental friendly (no phosphate and hydrazine) Increase of the boiler durability
