Cooling towers can be referred to as heat rejection systems. They carry out the transfer of heat to the atmosphere through the cooling of water to a lower temperature. Some usual applications for cooling towers are air-conditioning systems, water-cooling of equipment, and general manufacturing needs. The type of rejection of heat in a cooling tower can be defined as evaporative as it allows a small portion of the water being cooled to evaporate into a moving air stream for providing significant cooling to the rest of that water stream.
Scale deposits get developed by the precipitation and crystal growth at a surface in contact with water. Precipitation takes place when solubility exceed either in the bulk water or at the surface. Aggregations of scale deposit in cooling water systems abate the efficiency of heat transfer and the carrying capacity of the water distribution system. These cells hasten the rate of corrosion and lead to the failure of process equipment. On the other hand, Corrosion can be regarded as the destruction of a metal by chemical or electrochemical reaction with its environment.
Nalco WT-100 serves as a cooling water chemical which is a blend of selected polyphosphates and silicates. It helps in the prevention of corrosion and deposit formation in industrial and domestic water supply systems. It is also applied once through cooling systems and in domestic and potable water supply lines and fire fighting systems to help in the prevention of corrosion and scaling problems.
In cooling systems, corrosion is the root cause for two basic problems. The first and most obvious can be referred to as the failure of equipment with the resultant cost of replacement and plant downtime. The second is the reduced plant efficiency owing to loss of heat transfer – the result of heat exchanger fouling caused by the accumulation of corrosion products. Nalco WT-100 has been designed in such a way so as to help in the prevention of corrosion and scale formation in industrial closed cooling and hot water systems filled with soft water. Nalco WT-100 Chemical Suppliers are many and can be found through various business portals.
Various types of scale and corrosion inhibitors can be found in the ChemEqual directory which is the largest online directory for chemicals supplier all over the world wherein buyers can have a direct access to all the products and their equivalent brands along with having the convenience of sending direct enquiry to suppliers.
