Cooling Tower Water Treatment Chemicals

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.

With the rich experience of more than 4 decades we are doing our business and are proud to be counted as one of the trusted business partners of our clients. 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.



Boiler Water Treatment Chemicals

Boiler Water Treatment Chemicals

Boiler Feed water treatment chemicals removes dissolved oxygen and reduce corrosion in the feed water circuit and thus protects the equipment against damage and reducing the potential for unscheduled downtime. These chemical treatments also reduce the amount of metal oxides and metal hydroxides (rust) entering the boiler to maintain clean boiler tubes and improves fuel efficiency.

 

Boiler internal treatment chemicals maintains clean boiler tubes surfaces and minimize metal cavitations (corrosion) – reducing the chance of overheating or failure. Control of corrosion and scale deposition helps to increase plant reliability and availability. It protects equipment, and reduces over all maintenance and fuel costs. In addition, some treatment chemicals can reduce the tendency for boiler water to carry over to the steam, thus, protects super heaters and steam turbines from damages.

Boiler Water Alkalinity

Boiler Water Alkalinity

Corrosion in general terminology is the destructive attack of metal. Metal loss or damage can occur due to chemical & electrochemical reaction, physical erosion or biological attack. Corrosion is always because of chemical reaction. Water corrosiveness is determined by the impurities present in it. Oxygen, dissolved solids, gases and acids in water attack the common construction material.

Major Problems due to Corrosion:-

  • Metal loss (capital loss)
  • System leakage or burst
  • Water / Fluid contamination
  • Poor heat transfer (power loss)
  • Corrosions are of various types and differ with application to application.

Major Types of Boiler Corrosion:-

  • Uniform/General Corrosion due to high temperature
  • Pitting Corrosion due to high temperature and chloride
  • Galvanic Corrosion due to multi-metals
  • Oxidation Corrosion due to oxygen and carbon dioxide
  • Stress Cracking Corrosion due to high pressure and temp.



Boiler Descalant

Boiler Descalant

Descalants or Descaling Agents are chemical compounds that effectively dissolves, disperse or purge the scales, rust and soil deposits from heat exchangers and pipelines by means of re-circulation method, fill and soak method or immersion method. A descalant is always designed by keeping in mind the type of deposit and metallurgy of the system. Proper Corrosion Inhibitors are added in descalants to avoid damage to system metals.

After acidic descaling of system, it is important to passivate and neutralize the system with proper Passivating Agents for avoiding chances of flash rusting after descaling.

In some cases Scale Softeners and mechanical means like brushing and scrubbing of tubes is also required for heavily fouled systems.

Descaling is a labor oriented job and requires system downtime. Hence, the use of alternatives such as Online Descalants and Antiscalants are getting popular.

Chemtex offers a wide range of descalants under its registered trade names for various types of small, medium and large size boilers.



Coil Cleaner

Coil Cleaner

Chemtex’s Coil Cleaner is a non-acid liquid cleaner and brightener for complete removal of dust, dirt, greasy soils, carbon deposits and grime on the aluminum fins and copper coils of AHU, FCU, Air Conditioners, Car Condenser and Radiator, Air Cooled Chillers, Air Cooled Condensers, Air Cooler Tube Bundle etc. It can be used manually with normal, hydraulic or atomized sprayer.
