Under normal circumstances, the antifreeze replacement cycle of water-cooled machines is recommended to be changed once every six months, or once a year. Because the antifreeze will deteriorate after a long time, the antifreeze will become more corrosive and the viscosity will change, so it needs to be replaced regularly.

In general, the water-cooled machine after half a year of operation, it is necessary to replace the quality of antifreeze in a timely manner, and in the replacement of antifreeze, you need to take into account the quality of antifreeze good and bad. If companies use more money to buy higher-priced water cooler antifreeze, then after completing a replacement, even if the enterprise long-term operation of the chiller, the equipment can also be replaced again after a year of antifreeze.

And, when replacing the antifreeze in the water cooler, it is recommended to avoid mixing. Try to use the same brand of antifreeze, different models of antifreeze even if the main ingredients are the same, the use and formulation will be different, should not be mixed to avoid chemical reactions, precipitation or bubbles.
