Sulphamic Acid Based Descalants
Our high quality range of Sulfamic Acid
Descalant is non hazardous & non flammable, and does not give off
unbearable fumes. It's perfect for removing scales from cooling towers, coils, heat exchangers, condensers and
heating & cooling systems. it increases the efficiency of working of a plant and equipment on cooling and
cleaning surfaces by removing industrial scale.
A strong crystalline acid, It 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.
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, it 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, it is used for many diversified
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 is ideal for removing scales
from cooling towers, boilers, heat exchangers, coilers, condensers, and various other heating and cooling
systems. We also provide in self-indicating grade that changes colors to indicate that the efficiency of material
has been finished.

|Performance Enhancing Chemicals
||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.
||This formulation is recommended for scales containing high silica, Typical
examples are scales found in sugar evaporators, caustic evaporators in the
aluminum Industry and black liquor evaporators in the Pulp Industry
||This formulation is recommended for removal of scales from heat exchangers
were scales are very severe and hard
Application of Sulfamic Acid
- Used as an immersion liquid
- Used as filling with a descalant solution
- Used through circulation for consistent concentration though the closed circuit
- Used in cold as well as with temperature ranging from 40º to 60ºC
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
- 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
Advantages of Sulfamic Acid
- It is a very safe and highly effective descalant
- It provides good cleaning and reduces manual cleaning
- It is recommended for the cooling water for descaling the condenser on running plant basis
Applications of Sulfamic Acid
- It is used for descaling
- It is very efficient descaling agent and is widely used for cleaning a variety of industrial equipments, especially boilers, condensers, cooling tower and pipelines.
- In paper & pulp Industry, it is used to prevent pulp degradation due to temperature conditions existing at the chlorination and hydrochloride stage. It also permits bleaching at higher temperature
and lowers pH without loss of strength of fiber.
- It is used in manufacturing of Dyes, Pigments and in the dyeing of leather.
- It removes excess of nitrides used in the diazotization reactions in the manufacturing of dye stuffs and pigments. Nitrides, if present, in process water of effluents can also be removed by using.
- In Chlorine Stabilization, Chlorine gas in water form HOCL which reacts with Sulfamic Acid form N-Chloro-Sulphamic Acid to N-ChloroSufamic Acid more stable and yet has active chlorine, Because of this, it is used for stabilizing chlorine in swimming pools and cooling towers.
- In Electroplating and Electro-refining, 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.
- In Solutation and Sulphamation, it is used for sulphation and sulphamation of many organic compounds. Sulphation of alkyl pheno-ethylen oxide condensation products for detergents and sulphation of ethoxylated phenol-formaldehyde resins is preferable with Sulfamic Acid. Stronger agents cause unwanted ring sulphomation.
- In the Plastic industry, it finds application in the plastic wherever a curing agent is required which does not have the disadvantage of inorganic acids and which acts faster than organic acids.
- It is preferred greatly to HydrochloricAcid in household usage for its intrinsic safety value.
- It is used in the design of many types of therapeutic agents such as Antibiotics, Nucleoside/nucleotide Human immunodeficiency virus (HIV) reverse transcriptase inhibitors, HIV
protease inhibitors (PIs), anti-cancer drugs (steroid sulfatase and carbonic anhydrase inhibitors), anti-epileptic drugs, and weight loss drugs.
- It is used as an acidic cleaning agent for metals and ceramics.
- It is used frequently for removing rust and limescale.
- It is used in the industrial cleaning of dairy and brew-house equipment.
- It is used as a catalyst for esterification process.
- It is used in Dye and pigment manufacturing.
- It is used as an Ingredient in Denture Tablets, Fire Extinguishing Media.
- It is used in Pulp and paper industry as a chloride stabilizer.
Handling & Storage
- 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
