To prevent the cracking of condenser coils and the reticulation system in general, please the take the precautions below when operating in cold environments.
When the ambient temperature is lower than -10°C, it is necessary to add an antifreeze agent to prevent the recirculating water from freezing. Typical dosing rates for glycol based antifreeze is below, however please confirm this with the supplier.
|Glycol (%) ||0 ||10 ||20 ||30 ||40 ||50 ||58 |
|Freezing point (°C) ||-0.0 ||-3.5 ||-8 ||-15 ||-24 ||-36 ||-48 |
If the tower is idle when the ambient temperature is below 0°C, it will be essential to completely drain all water from the tower and associated piping.
