Powdered Descalant - Safe Acid Descaler mixture and Cleaner with colour pH indicator with Acid Inhibitor. RXSOL Powder Scale mixture effectively dissolves Calcium and Mineral scale depsoits.  it is safe and effective way to remove scale deposits from all types of water-cooled and water-heated equipmentThis descaler specifically formulated and developed to rapidly clean mineral scale from passages in water-cooled or heated equipment. It improves Plant Efficiency, Lowers Cost, Conserves Energy, Decreases Down-Time.

Very useful and effective products for removing scales obtained from water in heating and cooling systems e.g. boilers, condensers, heat exchangers, jackets and coils. It does not need to be heated up during cleaning. The uniqueness of this Descaler allows you to clean some equipment while still in operation utilizing a minimum of your own personnel.


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.

Tag Identification

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.


Powdered Inhibited Acid Descaler with Colour pH Indicator

Inhibited Powder Acid is available in H.D.P.E. bags of net 25 and 50 Kgs. Material. Sample packets of 100-200 gms. are supplied on request. 

Advantages of using Descalant Powder with Colour Indicator

  • High shelf life.
  • Specific storage/handing arrangement doesn't required hence no adulteration possible.
  • Very high scale Dissolving Power.
  • The solid can be directly charged to system eliminating the cost of system reduces the leave of scaling solids and acts as anti - descalant.
  • Accidental excess dosing does not affect the metal of the circulating system but it acts to remove the deposited scale from the system.
  • It is recommended to does into the cooling water for descaling the condenser on running plant.


  Descalant Powder with Colour Indicator is used for descaling.

•    RXSOL-37-8865-025 is very efficient descaling agent and is widely used for cleaning a variety of industrial equipments, especially boilers, condensers, cooling tower and pipelines.

At room temperatures, dilute aqueous Sulfamic Acid solution is stable for a long time but rapid hydrolysis occurs at elevated temperatures. Its solution is less corrosive toward metals than another mineral acid. When compared to most of the common strong mineral acids, Sulfamic Acid has desirable water descaling properties, low volatility, low toxicity and is a water-soluble solid forming soluble calcium and iron-III salts. Because of its many positive attributes like handling ease, solubility and low corrosiveness, Sulfamic Acid is used for many diversified applications.

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.

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.
