Ethylene Glycol Heat

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

Ethylene glycol

There is a difference in the mixing ratio depending on whether it is ethylene glycol or propylene glycol For ethylene glycol the mixing ratios are typically 30/70 and 35/65 whereas the propylene glycol mixing ratios are typically 35/65 and 40/60 It is important that the mixture is frost-proof at the lowest operating temperature (in Danish)
