Note! The specific gravity of ethylene glycol based water solutions are increased compared with specific gravity of clean water. Freezing Point of Ethylene Glycol based Water Solutionsįreezing points of ethylene glycol based water solutions at various temperatures are indicated below Properties differs so much from clean water that heat transfer systems with ethylene glycol should be calculated thoroughly for actual temperature and solution. Specific heat, viscosity and specific weight of a water and ethylene glycol solution vary significantly with the percent of ethylene glycol and the temperature of the fluid. Instead solutions based on propylene glycol are commonly used. Ethylene glycol should be avoided if there is a slightest chance of leakage to potable water or food processing systems. Ethylene glycol is also commonly used in heating applications that temporarily may not be operated (cold) in surroundings with freezing conditions - such as cars and machines with water cooled engines.Įthylene Glycol is the most common antifreeze fluid for standard heating and cooling applications. Ethylene Glycol based water solutions are common in heat-transfer applications where the temperature in the heat transfer fluid can be below 32 oF (0 oC).
