Ethylene Glycol based water solutions are common in heat-transfer applications where the temperature in the heat transfer fluid can be below 32 o F (0 o C).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.

Glycol Charts & About Glycol. ABOUT GLYCOL IN CHILLERS. A chiller will run without glycol as long as the fluid temperature in the system is above freezing. Glycol or other inhibitors are recommended for most process cooling applications even if the fluid temperature doesn’t reach temperatures near freezing.

For many heat-transfer applications it is necessary to use a heat-transfer fluid with lower freezing point than water. The most common antifreeze fluid - ethylene glycol - must not be used where there is a chance of leakage to potable water or food processing systems. In food processing systems the common heat-transfer fluid is based on propylene glycol.

A Guide to Glycols 10 Glycol-based solutions can give excellent burst protection across a wide range of cold temperatures as indicated in Figure 1. Consideration should be given to having appropriate expansion space for the solution and to the need for an inhibited glycol-based product such as DOWFROST*,

DOWFROST heat transfer fluids, the glycol affects the refractive index of the fluid in a similar fashion. aFreezing points are below -50°C ( 60°F). NOTE: Generally for an extended margin of protection, you should select a temperature in this table that is at least 3°C (5°F) lower than the expected lowest ambient temperature.
