Cooling Tower Water Treatment Chemicals

Industrial water treatment is for optimization of most industrial processes based on water, such as: heating, cooling, processing, cleaning, and rinsing, so that operating costs and risks are reduced. Cooling towers are heat removal devices used to transfer process waste heat to the atmosphere. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid or in the case of closed circuit dry cooling towers rely solely on air to cool the working fluid. Common applications include cooling the circulating water used in oil refineries, chemical plants, power stations and building cooling. Cooling towers can scale up and corrode, but left untreated, the warm, dirty water they can contain will encourage bacteria to grow.

We are a leading manufacturer and exporter of chemical compounds and chiller / HVACnR Chemicals which are used in various industrial purposes. Our offered range of chemical compounds is used to enhance the performance of the systems by making them free from corrosion, impurities and other undesired elements. Our company is located in Kolkata, and started its beginning in 1970.From the beginning till today we are producing and delivering best quality solutions with the certification of ISO 9001:2008. With the wide network and more than 25 distributors in the bigger cities all over India we are capable of delivering bulk of chemical products.

We are well acclaimed by our valuable customers and supported by them at domestic as well as international level. With the transparent & honest business ethics and practices we have successfully established a harmonic client-supplier relationship.


Cooling Tower Water Dispersants & Biodispersants

Cooling Tower Water Dispersants & Biodispersants

Cooling tower biodispersants are chemical compounds that are dosed in cooling tower water to prevent fouling of system due to biological growth such as algae, slimes and bacterial deposits. It helps to remove biofilms that are formed by these micro-organisms, which otherwise are difficult to remove by adding biocides. By removing biofilms, biodispersants helps to prevent mic (microbiologically induced corrosion). Cooling tower biodispersants increases the efficacy of other biocides and is completely compatible with all biocides and suitable for plant metallurgy. Biodispersants reduces the quantity of biocides or microbiocides to be dosed. Equivalent or even better than the followings:- indion 9077, indion 9078, nalco 2890 etc.

Cooling Tower Water Antiscalants

Cooling Tower Water Antiscalants

Cooling water antiscalants or scale inhibitors are chemical compounds that inhibit or prevent scale formation in the heat exchanger by means of sequestering calcium and magnesium salts, dispersing silica, chelating iron and breaking-up colloidal deposits like clay and silt that are otherwise formed in the heat exchanger. Antiscalants that are effective - are profitable for users for its round the year savings of power and labor, and increase in production. Use of antiscalant is a prime necessity to meet up with the huge production targets.


Chemtex’s range of cooling tower antiscalants is effective on untreated hard water with high ph range, tds, alkalinity, iron and silica content. Equivalent or even better than the followings:- indion 4296 / 4295 / 4294 / 4293 / 4292, nalco 3dt 129 etc.

Cooling Tower Water Biocides, Micro Biocides or Algaecide

Biocides function in removing and preventing spores, fungi, legionella pneumophila bacteria, and many other bacteria etc in Cooling Tower Water.

Biocides are very vital for healthy Cooling Water Treatment for their following benefits:-

  • They avoid plugging of nozzles with algae and biofoulants
  • They prevent water borne life taking diseases such as legionella disease
  • They improve heat loss because living organisms cause rise in temperature of water.


Equivalent or even better than the followings:- Indion 9040 / 9052 / 9053 / 9054, Nalco 7338 etc.

Cooling Water Scale & Corrosion Inhibitors

Cooling Water Scale and Corrosion Inhibitors are chemical compounds that inhibit scale formation in the heat exchangers and prevent corrosion or rusting of heat exchangers at severe water conditions.

CHEMTEX’S range of Scale and Corrosion Inhibitor are effective in severe conditions of hard and saline make-up water from LSI of -4.0 to +4.0. These products are designed and best suited for Ship Condenser (once through system). 

Antiscalants that are effective - are profitable for users for its round the year savings of power and labor, increase in production and extended system life. Use of anti-scalant is a prime necessity to meet up with the huge production targets.

Equivalent or even better than the followings:- INDION 9265 / INDION 4296 / INDION 4295 / INDION 4294 / INDION 4293 / INDION 4292 etc.
