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.
