Economical Mult-funtional Boiler Water Treatment


Price request




WTP S123BP is an economical, multi-functional boiler water treatment recommended for the complete control of (base exchanged) softened boiler feed water or RO permeate. WTPS123BP  will control residual calcium hardness found in the feed water or from condensate. Contains an alkalinity builder which will adjust hydroxide levels for correct chemical balance, and eliminate dissolved oxygen to prevent pitting corrosion.

WTP S123BP contains catalysed bisulfite to ensure rapid oxygen scavenging and antiscalants/dispersants/sequestering agents: copolymers, polyacrylates, phosphates.

All the raw materials used in the manufacture of WTP S123BP conform to the USA Food and Drug Administration Chapter 1 Subpart D – Specific Usage Additives, §173.310 Boiler Water Additives, under the stated conditions of use.” 

Product Data

Physical State Clear liquid
Specific Gravity (SG) 1.165
pH (product) 13-14
Sulphite content 7 % as NaHSO3


WTP S123BP dosage is proportional to the oxygen content of the feedwater and should be dosed to achieve acceptable pH and sulphite reserves.

Product ml per m3 feed = (74 x ppm Oxygen) + (375)/Boiler  concentration factor

This formula will give 30 ppm sulphite as Na2So3  

Where Feed temp = 80 0C     then ppm Oxygen  = 2.9 ppm

Testing and Control

WTPTK108 test kit can be used to determine correct levels of Sulphite in the system.
