How to Prevent Freezing of Heat Exchangers in Winter [Video]

To prevent freezing of heat exchangers in winter, you can do the following: 1. **Maintain fluid flow**: Ensure that water or liquid continues to circulate within the pipes, thereby preventing it from stopping and freezing. 2. **Add antifreeze**: Add an appropriate amount of antifreeze depending on operating conditions to lower the freezing point. 3. **Insulation and heating**: Wrap the pipes with insulation, and install electric heating tapes if necessary, to prevent freezing at low temperatures. 4. **Drain idle equipment**: Heat exchangers that are not in use for extended periods should have their internal liquid completely drained. 5. **Regular inspections**: Pay more attention to pressure and temperature changes in winter, and address any abnormalities promptly. In short, don’t let the water stand still and don’t let the equipment freeze – prevention is the easiest way to avoid problems! .
