Other appropriate applications for freeze protection would include: What is Burst Point Protection (Burst Protection)?Burst protection is sufficient if the hydronic HVAC system will remain dormant or inactive when the temperature drops below freezing and there is adequate space to accommodate the expansion of an ice/slush mixture. 0000017482 00000 n 0000032908 00000 n It just doesn't expand and burst until the rated -50.

Propylene Glycol Coolant is a transparent orange liquid. Written by Kupis on May 11, 2020 in Chart. 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. Ignore your friend, 1 cup/gallon is 1/16, about 6%. 0000003031 00000 n of a component, the boiling point of a mixture, and the specific gravity of the mixture. Specific gravity at the same conditions is 1.077. About 41% by weight of propylene glycol in water will get you to a freezing point of - 10° F. Since propylene glycol has a density of 1.04 g/cm^3, this corresponds to 42.5% by volume. 0000009925 00000 n 0000036763 00000 n Propylene Glycol, Arctic Protection ARCTIC PROTECTION – provides burst and freeze protection for chilled water, hydronic and other closed systems at temperatures as low as -100°F. The polyetheramines used to make the amidoamines are prepared from EO and propylene oxide. This will help to protect your system from glycol degradation, corrosion and bacteria as well as bringing system PH … Continued 0000018939 00000 n Measure the solution using a glycol refractometer. 0000058590 00000 n 0000032446 00000 n 0000027503 00000 n 0000025979 00000 n Glycols are heavy, syrup like fluids at full concentration, and become thinner when mixed with water. There are two basic protection points: Freeze Protection and Burst Protection. These questions ultimately affect the mixture ratio of the glycol. What is Freezing Point Protection (Freeze Protection)?Freeze protection is required in hydronic HVAC systems where fluid must continue pumping at the lowest anticipated temperature. 0000049347 00000 n The higher the concentration, the colder the mixture will provide protection. 0000036528 00000 n In food processing systems the common heat-transfer fluid is based on propylene glycol. 0000040222 00000 n This is the best way to add glycol as it guarantees the correct glycol concentration, and that the water used in the mixture is free of contaminants. 0000016942 00000 n 0000012753 00000 n Base Ethylene Glycol Phosphates Yes No Silicates Yes No Low Silicate Nitrites2 No Service Up to 5 years or Interval3 24–36 months Up to 5 years or 150,000 miles 150,000 miles 150,000 miles 150,000 miles 150,000 miles 100,000 miles and/or if system is opened 24 months General Motors pre-1995 For all makes, all models and all colors of antifreeze.
