WebNov 1, 2024 · These questions ultimately affect the mixture ratio of the glycol. For example if a coolant loop or system is being winterized and temperatures will fall down to -10°F at the lowest, a mixture of 30% propylene glycol to 70% water will be enough to protect the system. 30% propylene glycol has a freeze point of 8°F but the burst point is -18°F. WebA refractometer test measures the glycol concentration and gives the glycol freezing point of your solution. This instrument requires only a few drops of fluid for testing and requires no adjustment for fluid temperature. Need to increase your system's concentration (also known as correcting glycol concentration or balancing glycol concentration)?

Webin DOWTHERM heat transfer fluids, the glycol affects the refractive index of the fluid in a similar fashion. a Freezing 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. WebEthylene Glycol Freezing and Boiling Point Chart (DOWTHERM SR-1) Upon completing your glycol testing , you may need to increase your system's concentration using glycol addition. Our concentration correction calculator makes it easy to determine how much glycol is needed (100% concentrated) to bring your solution back to the required levels.

WebFor 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. WebFreezing Point: <40°F Flash Point: 266°F Autoignition: 1083°F.
