The Use Of Antifreeze In Closed Cooling Towers

During the use of closed cooling towers in winter, the problem of antifreeze has always troubled everyone.
The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze can prevent the coolant from freezing and bursting the cooler when the machine is shut down in cold seasons. But we have to correct a misunderstanding. Antifreeze is not just for winter. In the normal maintenance project of the equipment, the antifreeze needs to be replaced every year. There are many types of antifreeze, such as calcium chloride (CaCl2) in inorganic substances, methanol (CH3OH) in organic substances, ethanol (C2H5OH, common name alcohol), ethylene glycol (C2H4 (OH) 2, common name sweet alcohol), Glycerol (C3H5(OH)3, commonly known as glycerin), lubricating oil, and common sugar and honey in our daily life can be used as the mother liquid of antifreeze. Ionized water, such as distilled water, unpolluted rainwater, snow water, etc., can become an antifreeze in the general sense after the total hardness component concentration of the water quality is between 0-30ppm). Some people think that antifreeze is specially used for closed cooling towers in cold areas, which is a misunderstanding. The main component of antifreeze on the market is ethylene glycol, which has the characteristics of high boiling point and low freezing point. Antifreeze also contains additives to prevent oxidation of the glycol (which forms a very corrosive by-product), prevent corrosion, prevent foaming, and more.
