An animal would have to consume a lot more of this type of antifreeze, a quantity that is unlikely to be available, to get sick or to die. 0000006959 00000 n It maintains thermal circuits in perfect condition for longer periods of time than conventional products and much better than Propylene Glycol USP with water … 0000016861 00000 n Definitely go with a 50-50 ratio. Propylene glycol is also used to make polyester compounds, and as a base for deicing solutions. 0000008854 00000 n 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. 0000009399 00000 n 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. Any combination of EO and propylene oxide will work; however, the ratio of EO to propylene oxide may be tailored to control the water absorption. The bottle's label should tell you what is type of antifreeze it is. In food processing systems the common heat-transfer fluid is based on propylene glycol. 0000064709 00000 n Propylene glycol is less toxic, breaks down more rapidly and is more environmentally friendly. 0000039379 00000 n Specific gravity at the same conditions is 1.077. Ethylene glycol is the industry standard for closed loop freeze protection and is the product we use in most applications.

For many heat-transfer applications it is necessary to use a heat-transfer fluid with lower freezing point than water. 0000050136 00000 n 0000058568 00000 n 0000033579 00000 n Note that you should only protect up to the lowest anticipated temperature and no further, as there is a trade-off between efficiency and concentration. 0000037086 00000 n Since, at the time of writing, your top priority is clearly identified as "absorbs as much heat as possible," your ideal ratio is 100% water, 0% polypropylene glycol. Propylene Glycol To Water Ratio Chart. 0000032908 00000 n It just doesn't expand and burst until the rated -50. 0000025979 00000 n 0000003587 00000 n The higher the concentration, the colder the mixture will continue to protect. Propylene-glycol mixtures Remember that the -50 degrees is not the freezing point but bursting protection. 0000022592 00000 n This chart may only help to confuse. 0000050770 00000 n 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. here's a link to an article on Brewery Glycol Systems that might help too. 0000033239 00000 n ARTIC-GARD: 95/5 Inhibited Propylene Glycol; Economical formulation of 95.5% propylene glycol, dipotassium phosphate and deionized water offers good heat transfer characteristics, freeze and corrosion protection and low volatility.

A safe ratio is one part glycol / 2 parts water, this will give you a freeze point of approx +5 F. a solution freeze point 20 F below thermostat set point is a good target. 0000012753 00000 n The freeze point temperature should be 25°F below the lowest required setpoint (see chart). 0000008508 00000 n 0000040222 00000 n 0000034759 00000 n 0000047466 00000 n 0000026112 00000 n Propylene glycol is also known as 1.2 Propanediol. What is the Freezing Point and Burst Point of Propylene Glycol and Ethylene Glycol? There are two basic protection points: Freeze Protection and Burst Protection. This is in applications where no ice crystals can be permitted to form, or where there is inadequate space for expansion of an ice/slush mixture. 0000064147 00000 n 0000064732 00000 n 0000003053 00000 n Propylene Glycol Coolant is a transparent orange liquid. 0000024445 00000 n View glycol concentration chart or use our calculator to determine freezing point and burst point of propylene glycol and ethylene glycol. This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. If 100 per cent glycol is purchased then on-site mixing is required, and this can cause issues if not done properly. 0000047170 00000 n 0000077114 00000 n It’s recommended that you use a high-quality glycol with built-in OAT inhibitor packs to suit your process operating characteristics. 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. 0000046989 00000 n 0000002716 00000 n When we discuss freezing point protection, we are determining the coldest temperature at which the system fluid must continue functioning with little to no ice/slush mixture. 0000033474 00000 n 0000049872 00000 n 0000003031 00000 n 0000058590 00000 n We protect up to the lowest anticipated temperature (also known as the freezing point) by adjusting the antifreeze mix ratio, or the concentration of glycol in the heat transfer fluid. 0000026386 00000 n propylene glycol fluids are used because of their low acute oral toxicity vs. the moderate toxicity of ethylene glycols. 0000012472 00000 n 0000003863 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.

The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) You will also find below a chart showing concentrations of glycol fluids required to provide freeze and burst protection (also known as an antifreeze temperature chart, burst and freeze protection chart or glycol concentration chart). When we discuss burst point protection, we are determining the coldest temperature at which the system fluids will become ice/slush, but doesn’t freeze and expand enough to burst the piping and coils. 0000050427 00000 n In the common RV antifreeze of around 25-30% premixed it will start to form ice crystals around 15 degrees and solidify at -15.
