Tannin Based Scale & Corrosion Inhibitor for Steam Boilers & Closed Systems
Accepta 6305 is a Tannin based multi-functional boiler water treatment in solid form for softened water make-up application. This is a proprietary boiler water treatment containing Natural Tannins, high performance sludge & scale polymer conditioners and alkalinity builders.
Accepta 6305 is especially well suited for those systems with a low temperature feed water and also for feed systems that have either a feed pre-heater or economizer.
Accepta 6305 contains only ingredients approved under the United States Food & Drug Administration Regulations Title 21, Section 173.310 Boiler Water Additives.
HOW MUCH TO USE
Target is 140 ppm of Tannin in the boiler water, or sufficient to control feedline corrosion.
|Testing Method||In Boiler Water|
|Tannin – Steam Boiler||120-160 ppm|
|Tannin – Loop with Aluminum Exchanger||100-120 ppm|
System pH control is critical and will be a function of boiler feed chemistry and metallurgy, but the caustic alkalinity in the boiler should typically be maintained in the range of 250 and 750 ppm as CaCO3
Appearance: Solid – Dark Brown
pH: 10 @1%
