Freeze protection for dry coolers at -20°C?

Update Time:2026/4/20
In extreme cold (-20°C), freeze protection prioritizes ethylene glycol-based antifreeze and VFD fan control. Electric/electromagnetic heating modules are not mandatory; they serve only as auxiliary de-icing tools. A closed-loop system with properly concentrated glycol provides full protection.
