How to prevent freezing of dry coolers in winter?
1. According to the actual situation of the region and low temperature, add a certain proportion of antifreeze.
2. Add a steam coil (if the site allows) under the tube bundle to prevent freeze cracking.
3. A hot air blower is installed on site. When the equipment is turned on, the hot air blows the tube bundle, and the medium is slowly introduced until the temperature of the tube wall is greater than 15 °C.
4. When shutting down, pass clean compressed air through the bypass to dry the accumulated water in the inner cavity of the tube bundle.
