Dosage, Feeding & Control


Mercy Steam 6224 is normally fed continuously to the dearater or feed water storage tank and maybe fit directly to the feed line simultaneously with the scale inhibitor product.


Mercy Steam 6224 contains a blend of catalyzed sulphite and can be tested easily to get a reserve of 30 ppm sulphite.  A high feed temperature value will make the dosage rate of this product very low.


The removal of oxygen from boiler feedwater will reduce corrosion in all areas of the steam system, including feedlines, boilers and the condensate system.




Mercy Steam 6224 is packaged in 32 kg and 256 kg plastic drums.
