Properties of glycol at low temperatures:
- Example with 30% glycol by volume
- Ice slush starts to form at -16°C.
- There is risk for malfunctions at -30°C
No risk of damage by freezing with a minimum
content of 30% glycol by volume
% glycol by volume
Curve A: Ice build up starts (slush)
Curve B: Temperature at which damage due to
freezing can occur
1. Safe range
2. Malfunctions may occur (ice slush)
3. Risk of damage by freezing
