Technical Specifications:


APPLICATION : Boilers, calorifiers, heat exchanges, diesel engine cooling system, condensers, evaporators & other type of equipment where rust & scale form. 


Reddish / Yellowish / white – Powder ( without indicator )  
Density         1.2g/cm3
pH                 (10 wt %):1.1


Metal    Suitable aluminium, zinc, tin and their alloys. Stainless steel, Carbon Steel, Cast Iron, Titanium, Copper , Copper alloys, PVC, Plastic , Rubber  Rubber No known effect
Rubber No known effect

Efficiency :Rapid Softening, disintegration and dissolving of scales.


By reducing down-time, productivity is increased. by protecting metal and by uniform leaning of the surface equipment life is prolonged and performance made superior. The above information is adequate for commonly encountered problems of descaling.

Handling & Storage


•    No Fumes Avoid contact with skin or eyes. Wear Cup-type, rubber or soft plastic-framed goggles, protective clothing, and rubber gloves must be worn when handling.

•    Keep in a tightly closed container. Protect from physical damage.

•    Store in a cool, dry, ventilated area away from sources of heat, moisture and incompatibilities.

•    Containers containing this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.

•    Ensure as low exposure as possible. Local exhaust ventilation is generally preferred as it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.

The self-indicating grade that changes colours to indicate that the efficiency of material has been finished.
Colourless Solution showing Powerful Strength.
Light Brown-Yellow Solution indication Poor strength, In this stage addition of more powder required to dissolve the scale.
Blue colour solution will result in neutralization of Acidic Power, After completion of Descaling process system must be neutralized with ALKALI SOLUTION. When we'll put alkali solution into the used descaler - solution, Acidic power will get neutralized and BLUE colour will develop.

Suitable and very popular product for DESCALING of high and low pressure boilers, Heat EXCHANGERS etc. Its corrosion inhibitor blend PROVIDE metal protection

This is mixed with fresh water 3 to 20 percent depending on deposition of scaling. After using RXSOL-37-8865-025, Rinse all metal surfaces with 0.5 percent of RXSOL-20-2059-025 at least 2-4 house, up to neutrial of PH valve.

Procedure-of-use: The most effective descaling is accomplished by circulation.In the case of small components,the soak method in an immersion bath can be used. If the equipment to be cleaned is contaminated by oil, grease or sludge, then pre-cleaning with DEGREASER ( RXSOL OB 1005 ) is necessary. Depending on the extent of scaling, use a solution of 2.5-10% RXSOL-37-8865-025 . The solution will have a red colour which changes to orange when 85% of the acid has been neutralized , & to colourless  when the solution is totally neutralized. Whenever possible, the solution should be heated to 60°C.Neutralised  solutions can be re-activated by adding more RXSOL-54-1008-025  until the red colour reappears. This should not be done more than twice. RXSOL-37-8865-025  should not be used on Aluminium , Zinc, Tin or Galvanized surfaces.

Fields: Descaling of  Boilers, Descaling  of Diesel Engine Cooling Systems, Condenser, Pipeline collection system, Evaporators, Calorifiers, Heat Exchangers,The strength of the acid can be enhanced by adding 1part sodium chloride (common salt) to 20 parts of Descale Powder.If salt is not available, an acceptable alternative is to dissolve RXSOL-37-8865-025  in  water. After use of RXSOL-37-8865-025  a  0.5% solution of Alkalinity Control in fresh  water should be used for neutralization.

Evaporators, Calorifiers, Heat Exchangers:
The strength of the acid can be enhanced by adding 1 part sodium chloride (common salt) to 20 parts of Descale Powder RXSOL-37-8865-025. This enhancement of the cleaning solution, however, should not be used when descaling diesel engine cooling water systems. After use of Descale Powder a 0.5% solution of Alkalinity Control in fresh water should be used for neutralisation.

After using  RXSOL-37-8865-025, Rinse all metal surfaces with 0.5 percent of RXSOL-20-2059-025, at least 2-4 hour , up to neutral of PH value.

• Fast and effective scale remover.
• Soft on ferrous metals.
• Removes water scale & rust from boilers/diesel engine & other cooling system
• As well as from condensers, evaporators, & heat exchangers etc

Why Use RXSOL Descaler?

  • It is a safe , economical concentrated  chemical to be used on the waterside of heat transfer equipment.
  • You do not have to heat RXSOL-37-8865-025 .
    RXSOL-37-8865-025  is safer for the employees to use than other acid products.
  • Your equipment will be cleaned in only hours without disassembling any part of the equipment. Equipment can also be cleaned without any down time (cleaning on the run).
  •  Cleans down to the original surface without pitting.
  •  RXSOL-37-8865-025 is safe on copper, copper-nickel, bronze, brass, iron, stainless steel and rubber.
  •  RXSOL-37-8865-025  will extend the usable life of your equipment, especially when used as a part of a regularly scheduled preventative maintenance program.
  •  Removing the scale build up allows your equipment to operate more efficiently with less down time.
