Coolant Corrosion Inhibitor



Antifreeze helps prevent liquid from freezing in sub-zero temperatures, and preventing boil-outs above the designated boiling point of the same so that it doesn’t evaporate.

 A study confirms three-fifth of all engine problems are coolant-related. For an engine to operate optimally, only one-third of generated heat/ energy is required and the rest is released or transferred. If this transfer does not take place, it would lead to overheating of engine equipment, causing breakdown and/ or failure. Overheating adversely affects the engine's efficiency directly, affecting performance, fuel economy, maintenance, and longevity of vital engine components. Using recommended coolant ensures that the engine runs at an optimum temperature without any heat-related hassles.

 What is coolant to begin with?
Coolant, derived from antifreeze chemicals are commercial grade antifreeze chemicals used in automobiles, DG sets, heavy-duty systems, etc., protecting the engine from getting disintegrated/ damaged at higher temperatures by transferring the excess heat formed.
Generally, coolants used in engines are homogeneous mixture of glycol and water, reason being their flexible thermal properties like high boiling point, low freezing point, stable over a wide range of temperature but …

 … Is coolant enough?
Glycol oxidizes at high temperatures into organic acids: glycolic, glyoxalic, formic, carbonic and oxalic. These are highly corrosive and can be corrosive to the system metal causing problems like pitting, pinhole and stress cracking corrosion. Even the resulting contaminants present in glycol adding more to its rate, degrading the total working system.

 The main problems with this undesirable acidity are:
·         Affects metallic pipelines, which leads to failure of temperature balance owing to heat loss
·         Pitting causes irregular holes, gradually leading to leakage of coolant into the combustion chamber
·         Scale depositions disrupt the heat transfer efficiency of the coolant
To tackle these problems, coolant additives such as corrosion inhibitor chemicals were synthesized.

 Coolant corrosion inhibitor are chemical additives that when added to coolant to protect the internal surfaces from corrosion related adverse effects. These inhibitors made with components of the finest grade not only ensures efficient reduction in mineral scale and sludge deposits but also provides efficient protection to metallic components from corrosion with its unique features like anti-corrosion and system life enhancement.

 Coolant – Inhibitor Technology
·   IAT based: Inorganic Salt additives based coolant
·   OAT based: Organic Acid Technology based coolant
· HOAT based: Hybrid organic acid technology (HOAT) is combination of IAT and OAT technologies

Compatible with heavy duty coolant, comprising of glycol, water and corrosion inhibitors that control irregular pitting, scaling, etc. Heat produced by the engine is absorbed by the coolant which helps in maintaining regulated temperature in the system, transferring excess heat to the appropriate media and the incorporated inhibiting property makes the metallic surface inert against all types of oxidizing reaction of organic acids, ensuring corrosion free heat transfer system.
Coolant Corrosion Inhibitor provides anti-freeze properties, boil over protection, and component protection and meets all the requirements as per industry standards. These are formulated by making use of premium grade chemicals with sophisticated methodologies for anti-corrosion, anti-scaling, and anti- fouling properties.

RO Antiscalant

Reverse Osmosis serves as one of the most critical processes that are involved in the process water treatment to clean water, utilized in various industrial process applications. Reverse Osmosis can be regarded as the process wherein semi-permeable membranes help in separating purified water from contaminated water. It occurs when a pressure is applied to the concentrated side of the membrane resulting in forcing purified water to the dilute side. Reverse Osmosis is very efficient for the treatment of brackish, surface and ground water for both large and small flow applications. Some examples of industries that use RO water include boiler feed water, food and beverage, pharmaceutical, metal finishing and semiconductor manufacturing to mention a few. The overall performance of a reverse osmosis system relies on various factors like feed water quality, membrane type, flow control, temperature and pressure. Systems must be well maintained for ensuring effective performance with any

Hybrid Organic Acid Technology (HOAT) Coolant

Optimal use of machines is directly proportional to its engine performance. What an engine does is it converts the supplied energy into its mechanical form, driving the machine to work. Engines require one-third of total heat that is generated during conversion and the rest of the heat is needed to be evacuated from the combustion chamber which would otherwise lead to engine failure. Earlier, water was preferred as an ideal coolant for quite a period of time but the problem started to arise when the temperature would become extremely high or low, to be precise temperature more than 100 ° C and below 0°C. To get rid of this problem, coolants were formulated. Coolants are categorized chemicals that increases the boiling point of the fluid and decreases the freezing point of the fluid to make it suitable for use in extreme heat and freezing conditions. Coolants are a proportionate mixture of antifreeze and solvent, mainly glycol and water. Ideally utilized as a preventive in

Antiscalant Chemical for RO Plant

  Reverse Osmosis System is a revolutionary invention to treat water and provide an effective solution for purifying water in various applications. The performance of RO can be ensured by the formation of scale and deposits on the membranes, leading to reduced efficiency and increased operational costs.   To prevent this issue, antiscalant chemicals play an important role in reducing the formation of scale and maintaining optimal RO Plant performance. Reverse Osmosis is widely used in various industries to treat water and to remove impurities such as salts, minerals, and other contaminants. The dense, thin, and semi-permeable layer allows water molecules to pass through while rejecting dissolved solids, and other impurities such as salts, minerals, and other contaminants. But the major issue that surfaces in such systems is the formation of scales due to the build-up of dissolved minerals and salts on the surface of the RO Membrane.
