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 a device from overheating due to its high boiling point and low freezing point property, these chemicals are indulged with anti-corrosive, anti-scaling, and anti-microbial properties, protecting the same from the adverse effects extremely low as well as high temperatures. The coolants are processed with latent heat addition, improvising the cooling efficiency of the same. Coolant Additives are mostly utilized in automobiles, machines, HVAC and various other industrial processing.

Considering the variety of utilization and applications, two new types of coolants are used in most of the HVAC engines are:

  • ·       OAT Coolant: Based on Organic Acid Technology, OAT coolants are free of silicates and manifests provides excellent protection to aluminum at high temperature.
  • ·       HOAT Coolant: Hybrid Organic Acid Technology is based silicates free, nitrates free and borates free formulation, incorporated with OAT technology which are suitable to be used in HVAC as well as less combusting application. The HOAT package is uniquely designed to protect aluminum, brass, copper, solder, steel, cast iron, aluminum alloys and other components such as rubber hoses, gaskets, rubber seals, and elastomers commonly found in the engine radiator.
The HOAT Coolant Additives also help the industrial equipment to produce superior performance by rendering them protection from metal sludge and scale deposits and any contamination in the radiator. Corrosion Inhibitors are nowadays used in the composition of these Coolant Additives during processing so as to ensure perfect protection to equipment from corrosive attack.

Using HOAT coolant in engines and radiators ensures following benefits:


  • ·         Extended operational life for heating and cooling systems
  • ·         Excellent anti-corrosion and anti-scaling properties
  • ·         Higher stability compared to normal coolants; Does not get reduced with time
  • ·         Prevents pitting corrosion
  • ·         Prevents the fluid to get over heated, showing effective control on fluid temperature be it high or low
  • ·         Lower environmental impact
  • ·         Excellent compatibility with Aluminum, Rubber and Elastomers
  • ·         Non-foaming
  • ·         NAP free Coolant

H2S – A Silent Ultimatum to Oilfields

H 2 S Scavenger Chemical – Introduction The world has witnessed a substantial increase in E&P of crude oil to meet the need for globalization, leading to drilling of ‘deemed undesirable’ sites, owing to the presence of higher concentration of acidic gases like hydrogen sulphide, carbon dioxide, etc. These hazardous gases require proper measures before disposal or scavenging. Of these, Hydrogen sulphide/ H 2 S is the most threatening one, especially in confined or ill ventilated places. The characteristic rotten egg smell makes H 2 S recognition easy even at lower concentrations. Hydrogen Sulphide is toxic, acidic and extremely corrosive at higher concentrations. Heavier than air, it is found more near base level of the working sites. Then comes its inflammability, which may cause explosive reaction with air molecules. With peroxides, ammonia and other oxidizing chemicals, H 2 S often goes through combustible reactions,

Chemtex Cooling Tower BioDispersants are chemical compounds that are dosed in cooling tower water to prevent fouling of system

Some systems in chemical industries   are mainly comprised of Cooling water.These cooling water is continuously fed through various circulation pipes. The system comprising of such cooling water in huge amount needs to be cleaned in regular intervals.Otherwise various biological microorganisms such as algae,slimes & bacterial deposits are known to get accumulated.These microorganisms are known to cause MIC(Microbiologically Induced Corrosion) In such a scenario biocides can be fed but they are unable to remove biofilms . Chemtex Cooling Tower Biodispersants are very much able to remove such biofilms.They are also extremely compatible with all types of biocides. Cooling tower biodispersants indirectly does collaborative job with biocides in these two ways. ·          It increases the efficiency of biocides & microbiocides. ·          It reduces the quality of biocides to be dosed in cooling tower water. Chemtex manufactures dispersants & biodispersa
