Boiler chemicals are water treatment agents used in boilers and cooling towers. Since the operation of any boiler—whether fire-tube or water-tube—requires water as a key element for steam production, untreated water can lead to various problems, such as scale formation and corrosion. However, these issues can be prevented through proper water conditioning before use in the boiler, along with the addition of chemicals that inhibit scale buildup and corrosion.
Even a thin layer of scale deposits (especially in water-tube boilers) can cause the boiler’s metal to reach extremely high temperatures. This leads to structural damage such as deformation, cracks, ruptures, or tears caused by internal boiler pressure, which may ultimately result in a boiler explosion. Furthermore, scale acts as an insulator that reduces heat transfer through the boiler walls, causing higher fuel consumption and significantly increasing steam production costs.

In addition, the turbidity or impurity of water can cause soil - like scale deposits with an appearance similar to wood bark. This type of scale cannot be removed by acid cleaning circulation, as it does not react with acid like limestone scale formed from hard water. Instead, this scale is formed from fine dust and impurities in the water. When these tiny particles come into contact with hot steel surfaces at high temperatures, they adhere to the metal and gradually build up in thickness over time during operation.
Therefore, without the addition of boiler chemicals to prevent scale and corrosion, the boiler’s lifespan may be shortened, energy consumption will increase, and operations may need to be halted for boiler repairs, causing significant production losses. Moreover, boiler chemicals also help prevent and remove soot buildup in the combustion chamber and improve the boiler’s heat transfer efficiency.
Introducing TANDEX B.W.S. boiler chemicals – the best solution for boilers.
Prevents the formation of hard scale, which obstructs heat transfer in boilers, by conditioning water hardness into soft sludge that can then be removed through blowdown.
Protects the boiler’s steel surfaces from corrosion by absorbing the oxygen present in the feed water, which is a major cause of boiler corrosion.
TANDEX B.W.S. can form a thin protective film on steel surfaces without reducing the heat transfer efficiency of the boiler.
Saves costs on fuel, water, and chemicals since TANDEX B.W.S. does not increase the total dissolved solids (TDS) in the boiler. This makes water quality control easier and eliminates the need to increase the blowdown rate.
Reduces the problem of carryover, as the use of TANDEX B.W.S. does not increase the total dissolved solids (TDS) in the boiler. (High TDS levels in the boiler are a major cause of carryover.)
Easy to use and non-hazardous upon contact, making it suitable for use in food production facilities.
Therefore, to maximize boiler efficiency and extend its service life, adding TANDEX B.W.S. boiler chemicals is the proven solution to eliminate scale and corrosion problems.
