4 Νοε 2012 · Ethylene Glycol is the most common antifreeze fluid for standard heating and cooling applications. Ethylene glycol should be avoided if there is a slightest chance of leakage to potable water or food processing systems. Instead solutions based on propylene glycol are commonly used.

Mixtures of Ethylene Glycol and water are commonly used as an antifreeze or heat transfer fluid, such as in our GlycoChill+ E-series Heat Transfer Fluids. Here are the chemical and physical properties of Ethylene Glycol/water mixtures.
Properties of a 50-50 ethylene glycol-water mixture: Freezing point: Approximately -37°C (-34.6°F). This mixture offers excellent low-temperature protection, helping to prevent freezing in the cooling system. Boiling point: Around 106°C (222.8°F) at atmospheric pressure. The boiling point can be further increased with a pressurized cooling ...
Water, either purified or deionized, is the most common and efficient coolant used in recirculating cooling systems, making it a standard for comparison to other coolant fluids. Other common coolant types include ethylene glycol, propylene glycol, mineral oil, and dielectric fluids.
The mixture of ethylene glycol with water provides additional benefits to coolant and antifreeze solutions, such as preventing corrosion and acid degradation, as well as inhibiting the growth of most microbes and fungi. [20]
Conventional heat transfer fluids such as water and ethylene glycol (EG) can be used for cooling fluids in car radiators, and have relatively poor heat transfer performance. One method for...
Typically either ethylene glycol or propylene glycol are used in HVAC closed loops, with the type of glycol and its concentration determining the freeze point and other physical properties (see Table One). In HVAC applications, ethylene glycol is more widely used because of its lower cost, lower viscosity and better heat transfer properties.
