Attention To The Use Of Cooling Tower Antifreeze

Note 1: Try to use the same brand of antifreeze. Different brands of antifreeze use different metal corrosion inhibitors, so different brands of antifreeze cannot be mixed.

Note 2: The validity period of antifreeze is mostly two years (individual products will be longer), and it should be confirmed that the product is within the validity period when adding it; when replacing, the old fluid should be cleaned, and the cooling system should be cleaned before replacing it with new fluid. ;

Note 3: Antifreeze of organic type can be mixed with water, but the water should not be mixed too much. The addition amount is mainly determined according to the low temperature value to be protected against freezing, and the specific ratio should refer to the instruction manual on the outer package of the antifreeze solution. The following examples are for reference only: Example 1: When the minimum ambient dry bulb temperature (air temperature) is expected to be -10°C in the local area of the user, 20-30% high-content antifreeze and 70-80% pure water should be added. Finally, it is found that the water is still frozen, and it should be considered to continue to add a certain proportion of antifreeze until it is no longer frozen. Example 2: When the minimum ambient dry bulb temperature (air temperature) is expected to be -20°C in the local area of the user, it is better to add 40-50% high-content antifreeze and 50-60% pure water until it no longer freezes. By analogy, the lower the antifreeze temperature point, the higher the proportion of antifreeze liquid should be added. It is accurate to use the actual non-freezing and freezing, please master flexibly.

Note 4:Do not add tap water directly, but add distilled water or deionized water. If there is no condition, adding cold boiled water is better than adding tap water. If the antifreeze is lost due to leakage, add antifreeze of the same brand.

Note 5:Some antifreeze fluids will have a small amount of flocculent precipitation after being stored for one year. This phenomenon is mostly caused by the precipitation of additives, so it is not necessary to throw them away. If a large amount of particle precipitation occurs, it indicates that the antifreeze has deteriorated and can no longer be used.

Note 6:Another key to choosing antifreeze is to ensure safety. High-grade antifreeze has the functions of anti-corrosion, anti-scaling, anti-boiling, anti-freezing, anti-rust, etc., and can also protect the water tank very well, so it can be used all year round. The appearance of high-quality antifreeze should be clear and transparent, with eye-catching colors and no peculiar smell, while some inferior antifreezes do not have the functions of antifreezing and preventing boiling at all. The water tank and pipelines are "bitten" and full of holes, which affects the use. For details, please refer to the "Product Instruction Manual" compiled by JIANGSU GEWABIN HEAT TECHNOLOGY CO.,LTD.
