Sulfamic Acid Inhibited - Sulfamic Descalant
Sulphamic acid is very useful products for removing scales obtained from water in heating and cooling systems e.g. boilers, condensers, heat exchangers, jackets and coils
Sulfamic Acid is a Zwitterion, a molecule with two charges that counteract each other, the Nitrogen and Oxygen have a greater pull on the bond pair of electrons due to the high electro-negativity, this causes the bond to be polar, the Nitrogen and Oxygen draw the electrons closer and become slightly negative, the Hydrogens become positive because the negative electrons are further away.
The GP grade may be used for removing scales obtained from water in heating and cooling systems e.g. boilers, heat exchangers, condensers, jackets and coils.
The SR grade of Sulphamic acid:
This formulation is recommended for scales containing high silica. Typical examples are scales found in caustic evaporators in the Aluminum industry and black liquor evaporator in the pulp industry.
This formulation is recommended for removal of scales from heat exchangers made of Titanium metal. We provide Sulfamic Acid descalant that has scale solubilizing capacity and added corrosion resistance blends which offer maximum protection to metal of equipment being cleaned. Our range of Sulfamic Acid descalant is ideal for removing scales from cooling towers, boilers, heat exchangers, coilers, condensers, and various other heating and cooling systems. We also provide Sulfamic Acid descalant in self-indicating grade that changes colors to indicate that the efficiency of material has been finished.
CHEMICAL STAGE :
A strong crystalline acid, Sulfamic Acid is also known as an intermediate compound between Sulfuric Acid (H2SO4), and Sulfamide (H4N2SO2) and a dry, non-volatile, non-hygroscopic, odorless, white crystalline, stable acid, moderately soluble in water that forms strongly acidic aqueous solution, comparable in acidity to the common strong mineral acids.
In industrial water systems, scale accumulation is a persistent problem that can reduce heat-transfer efficiency, restrict water flow, increase energy consumption and accelerate equipment deterioration. RXSOL Sulfamic Acid Inhibited is an inhibited acid descaler formulated for the controlled removal of mineral scale and deposits from industrial equipment.
Sulfamic acid is widely used as an acidic cleaning and descaling agent for metals and ceramics. Its aqueous solutions can dissolve carbonate and other mineral deposits while generally offering lower metal attack than some stronger mineral acids.
RXSOL Sulfamic Acid Inhibited is a sulfamic-acid-based descaling chemical containing corrosion-inhibiting chemistry. The inhibitor is important because acid cleaning must remove mineral deposits while minimizing unnecessary attack on the underlying metal.
RXSOL identifies the product as RXSOL-43-1304-125, with an active-matter specification of approximately 95-96% for the inhibited sulfamic-acid product.
The product is supplied as a dry crystalline material that dissolves in water to produce an acidic cleaning solution.
Many industrial deposits contain calcium carbonate and other mineral salts. When sulfamic acid contacts acid-soluble scale, the deposits react with the acid and are converted into soluble sulfamate salts and other soluble products.
This allows the hard mineral layer to progressively dissolve and detach from the equipment surface.
Sulfamic acid is particularly useful for carbonate and certain sulfate-containing deposits, and technical references note that it can be more effective than hydrochloric acid for some sulfate scales.
Using an acid without corrosion protection can result in unnecessary metal loss during descaling.
Research into sulfamic-acid cleaning has demonstrated that metals such as mild steel, aluminum, copper and brass can undergo corrosion in sulfamic-acid solutions, while suitable inhibitor systems can substantially reduce this attack.
The corrosion inhibitor in an inhibited formulation is therefore intended to provide an additional layer of protection while the acid performs the descaling process.
This makes inhibited sulfamic acid particularly useful for circulation cleaning and immersion cleaning of industrial equipment, provided that the metallurgy, temperature and concentration are appropriate.
White crystalline soild, non volatile, non volatile, non hydroscopic. Soluble in water and odorless. Toxic by ingestion.
Uses: Metal and ceramic cleaning, amine sulfamates, ph control, hard water scale removal, electroplating.
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 other 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.

Chlorine gas in water form HOCL which reacts with Sulphamic Acid form N-Chloro-Sulphamic Acid to N-ChloroSufamic Acid more stable and yet has active chlorine, Because of this, Sulphamic Acid is used for stabilizing chlorine in swimming pools and cooling towers.
Metal sulphamate electrolytes values for their high solubility cadmium, cobalt nickle, lead silver and radium sulphamte deposits are bright and dense. Lead sulphamate is used in refining lead when a high quality is desired.
Sulphamic acid is used for sulphation and sulphamation of many organic compounds. Sulphation of aklyl pheno-ethylen oxide condensation products 9for detergents and sulphation of ethoxylated phenol-formaldehyde resins is preferable with Sulphamic Acid. Stronger agents cause unwanted ring sulphomation.
Sulphamic acid finds application in the plastic wherever a curing agents is required which does not have the disadvantage of inorganic acids and which acts faster than organic acids.

RXSOL Sulfamic Acid Inhibited can be used for removing water-formed scale from equipment such as:
RXSOL published product information specifically identifies boilers, condensers, heat exchangers, jackets, coils and other heating/cooling systems as applications.
DIRECTION OF USAGE
• Machines should be rinsed with water to remove loose flakes & sludge's before use
• Powder should be added to warm water for an ideal solution
• Sample should be properly tested before using
• Proper ventilation is essential for effective usage of Sulfamic Acid Descalant
• After cleansing, the solution should be drained out and the system should be rinsed with water until pH value is neutral
• Rinsing with ROTO PASS – 212 for better metal prevention and passivation is recommended
One of the major advantages of sulfamic acid is its suitability for circulation cleaning.
A typical chemical-cleaning sequence is:
System isolation → water flushing → preparation of sulfamic-acid solution → circulation → monitoring → draining → water rinsing → neutralization, where required → final flushing
Circulation provides continuous contact between the descaling solution and the deposited scale and helps maintain relatively uniform cleaning conditions.
Sulfamic acid solutions are also suitable for immersion cleaning where the equipment or components can be safely removed from service.
The required concentration depends on:
Technical references describe sulfamic-acid cleaning solutions in the approximate 5-20% range for certain metal-surface descaling applications, while other documented industrial descaling systems use lower concentrations depending on the equipment and operating conditions.
Therefore, the concentration should be selected based on the actual scale and equipment rather than using one concentration for every application.
Sulfamic acid is generally slower than hydrochloric acid at ambient conditions. Increasing the cleaning temperature can accelerate the descaling reaction, but temperature must be controlled because both acid activity and metal corrosion can increase with temperature.
Published technical guidance indicates that sulfamic-acid solutions may be heated substantially to obtain faster cleaning, while specific inhibited systems have recommended temperature limits depending on the metallurgy and inhibitor package.
For this reason, the product TDS and equipment manufacturer's material-compatibility requirements should always govern the operating temperature.
Sulphamic 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.

Acid compatibility should never be assumed solely from the fact that the product is inhibited.
Before cleaning, verify:
A laboratory or small-scale compatibility test is recommended for unfamiliar deposits or mixed-metal systems.
Sulfamic acid is still an acid and must be handled accordingly. Appropriate PPE, ventilation, chemical-resistant gloves, eye/face protection and established chemical-cleaning procedures should be used.
The cleaning solution should be monitored during the operation, and the spent solution should be collected and treated according to the site's wastewater and environmental requirements.
Claims that inhibited sulfamic acid is "safe for metals" should therefore be understood as conditional on correct concentration, temperature, exposure time and material compatibility, rather than meaning that the acid cannot corrode metal.
The principal difference is that an inhibited product combines the descaling action of sulfamic acid with a corrosion-control package.
This is particularly valuable when cleaning valuable industrial equipment where controlling metal loss is important. Studies have specifically investigated corrosion inhibition in sulfamic-acid solutions because the acid can attack susceptible metals even though its corrosion behavior may be less aggressive than some other mineral acids.
