Mixing water with coolant is a common practice in various industries, including automotive, industrial, and agricultural sectors. However, it’s essential to understand the risks associated with this practice and whether it’s acceptable or not.
The Chemistry of Coolant and Water
Coolant, also known as antifreeze, is a mixture of water and ethylene glycol (EG) or propylene glycol (PG) that is used to regulate the temperature of engines and other equipment. The EG or PG in the coolant is what gives it its antifreeze properties, allowing it to lower the freezing point of water and prevent it from boiling at high temperatures.
When water is mixed with coolant, the resulting mixture can be hazardous due to the following reasons:
- The EG or PG in the coolant can react with water to form a corrosive compound called acetaldehyde, which can damage metal surfaces and cause equipment failure.
- The mixture can also lead to the formation of acid, which can corrode engine components and other metal parts.
