Water which we get in nature is never 100 percent pure. It is contaminated with foreign substances – solids, liquids, gases and micro-organisms.                                                                                                                                                                      

Re-circulating Cooling Water System was in a neglected field in some early installations. But of late it has been observed that the efficiency and economy of many industrial process Units like Power Generation, Refrigeration & Air Conditioning, Chemical Processing, Furnace Cooling, Diesel Generator, Gas / Air Compressors etc. depend to a great extent on the efficient functioning of Cooling Water System.                                                                                                                                             

It has been observed that even one or two degree improvement of heat transfer rate through cooling water system may decide the profit and loss of a Manufacturing Unit. The cooling water system and its performance therefore is now being given its due share of importance and included in the top priority area in Industries. Pre-cleaning and Passivation is one of the important aspect of Cooling Water Conditioning before regular treatment.                                                                                                    

Satisfactory performance of any Industrial Cooling Water Conditioning Programme depends on proper Monitoring and Control. Required concentration of conditioning chemicals and proper balance with other dissolved ions shall be maintained. Without scientific Monitoring & Control no desired result can be achieved.

(HVAC / Air Conditioning, Gas / Diesel Engines, Furnace Cooling etc.)

Closed Re-circulating Cooling Water Systems are well established to cool Gas / Diesel Engines, Compressors, Furnace Cooling etc. Closed circuit cooling systems are also widely used in HVAC / Air Conditioning chilled water systems to transfer the refrigerant cooling to air washers, in which the air is chilled. In closed circuit cooling system, heat, absorbed by the water from the hot surface, is transferred by a water-to-water heat exchanger to open re-circulating water, from which the heat is released to atmosphere through evaporative cooling tower.                                                                                                                       

In Closed System, there is no evaporation and minimum make-up water is required, therefore, dissolved solids do not concentrate in circulating water. Hence, water born deposits / scale are not a major problem in closed systems.                                                                                                                                                                                                                                                                                                                     

In closed systems, the dissolved oxygen enters through make-up water and cannot be vented freely like open system and may cause severe corrosion.                                                                                                                                                                                                                                                                                                                                                                                

For Air Conditioning System – Condenser is an important component in Chiller and operating condition of the Condenser is the key factor that affects the efficiency of the unit. When scaling and fouling in the Condenser increase, the power consumption of Chiller will also increase, as a result the efficiency of the Chiller will decrease too. It is an established fact that an Air Conditioning System consumes about 65-70% of the total energy / electricity consumption of a building.

The basic philosophy for Boiler Feed Water and Boiler Water Chemical Treatment is to combat System Corrosion, Scaling and Un-scheduled Shutdown due to Premature Boiler Tube failure by providing high quality water with proper and effective Water Conditioning Programme.                                                                                                                                                      

The efficiency and fuel economy of steam generation system is to a great extent depends on the Waterside Scale control. It is difficult to precisely quantify the loss of fuel due to Scaling but it is possible to understand the magnitude of the fuel loss from the thermal conductivity difference. It is known that the scale has a thermal conductivity only 3% - 4% than that of steel. It is known that a minor drop of plant efficiency due to Scaling may mean annual loss in terms of millions for a medium size steam generating plant. In view of this, strict control on Boiler Feed Water and Boiler Water Chemistry is gaining its importance and is in the top priority agenda.                                                                                                                                                                                                                                                                                                                                                                                   

In addition to strict adherence of Boiler Water Control Chemistry the presence of Dissolved Oxygen in the Boiler Feed Water also deserve special attention because it is the greatest single Corrosive Factor in the entire Boiler Water Circuit.
