When the temperature remains above 5°C for an extended period, it's advisable to replace the antifreeze in the industrial chiller with purified water or distilled water. This helps reduce corrosion risks and ensures stable operation of the industrial chillers. As temperatures rise, timely replacement of antifreeze-containing cooling water, along with increased cleaning frequency of dust filters and condensers, can prolong the lifespan of the industrial chiller and enhance cooling efficiency.
