Propylene glycol and ethylene glycol are both used as antifreeze for cars and trucks They are chemically similar in many respects, with propylene glycol considered to be a safer alternative than its ethylene cousin; however, ethylene glycol has better heat transfer properties. Example - the specific heat of an ethylene glycol water solution 50% / 50% is 0.815 at 80 o F (26.7 o C). If 100 per cent glycol is purchased then on-site mixing is required, and this can cause issues if not done properly.

We protect up to the lowest anticipated temperature (also known as the burst point) by adjusting the antifreeze mix ratio, or the concentration of glycol in the heat transfer fluid. It’s recommended that you use a high-quality glycol with built-in OAT inhibitor packs to suit your process operating characteristics. 0000005458 00000 n Selecting The Proper Glycol Concentration For Closed Loop Hvac Systems.

Glycols are heavy, syrup like fluids at full concentration, and become thinner when mixed with water. Look where that puts you on this chart (EG is ethylene glycol, PG is propylene glycol): Joseph_E_Meehan. 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. 0000039673 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 … Calculate Concentration for Glycol Freezing Point or Burst Point Protection. Propylene-glycol mixtures Remember that the -50 degrees is not the freezing point but bursting protection. 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. G&D Chillers recommends a 35% Inhibited Propylene Glycol to 65% water (24.75 brix). 0000027093 00000 n The higher the concentration, the colder the mixture will continue to protect. 0000036259 00000 n 0000064147 00000 n 0000026720 00000 n 0000012472 00000 n 0000004634 00000 n 0000032032 00000 n 0000064296 00000 n 0000032446 00000 n This chart may only help to confuse. 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. 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. This will help to protect your system from glycol degradation, corrosion and bacteria as well as bringing system PH … Continued Ethylene glycol is the industry standard for closed loop freeze protection and is the product we use in most applications. 0000022748 00000 n 0000055466 00000 n 0000074155 00000 n 0000049872 00000 n 0000011765 00000 n 0000036528 00000 n 0000064732 00000 n 0000012306 00000 n 0000008854 00000 n There are two basic protection points: Freeze Protection and Burst Protection. For many heat-transfer applications it is necessary to use a heat-transfer fluid with lower freezing point than water. 0000003053 00000 n Water evaporates from the mixture, and if you continue to add a premixed solution, eventually you will have too much glycol. 0000026112 00000 n The chart below provides conversion to degree brix. 0000002716 00000 n What is the Freezing Point and Burst Point of Propylene Glycol and Ethylene Glycol?

Freezing Points of Methanol/Water Solutions % by Weight % by Volume 10° 0° TEMPERATURE °C NOVOSOLUTION.CA-10° -20° -30° -40° -50° -60° -70° -80° -90° -100° -110° -120° -130° In food processing systems the common heat-transfer fluid is based on propylene glycol. 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.) 0000031750 00000 n 0000025426 00000 n 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. There are two basic types of glycol protection available for your closed-loop HVAC system: “burst protection” and “freeze protection.” Burst protection is sufficient if the 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 CONVERSION CHARTS ETHYLENE GLYCOL & PROPYLENE GLYCOL The Conversion Charts below are to be used with the PPE Precision Specific Gravity Hydrometer and Beaker. The freeze point temperature should be 25°F below the lowest required setpoint (see chart). 0000033579 00000 n of a component, the boiling point of a mixture, and the specific gravity of the mixture. 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. %PDF-1.2 %���� 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. Glycol Calculator: Determine Required Concentration for Cold Weather ProtectionUse our Concentration Calculator to determine the required concentration of inhibited glycol fluid needed for your desired cold weather protection. View glycol concentration chart or use our calculator to determine freezing point and burst point of propylene glycol and ethylene glycol. It is safe to handle as it is composed of propylene glycol. Our testing found the the freezing point of the prop/water mixture was -15F.

Propylene glycol and ethylene glycol are both used as antifreeze for cars and trucks They are chemically similar in many respects, with propylene glycol considered to be a safer alternative than its ethylene cousin; however, ethylene glycol has better heat transfer properties. Example - the specific heat of an ethylene glycol water solution 50% / 50% is 0.815 at 80 o F (26.7 o C). If 100 per cent glycol is purchased then on-site mixing is required, and this can cause issues if not done properly.
