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. 0000050065 00000 n 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.) %PDF-1.2 %���� 0000006959 00000 n 0000032446 00000 n 0000027093 00000 n Propylene Glycol Coolant is a transparent orange liquid. These questions ultimately affect the mixture ratio of the glycol. It is safe to handle as it is composed of propylene glycol. Many glycol vendors will provide glycol that is already pre-mixed. 0000080011 00000 n 0000067651 00000 n Selecting The Proper Glycol Concentration For Closed Loop Hvac Systems. 0000003053 00000 n 0000037086 00000 n 0000003261 00000 n 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.

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. A glycol system (see schematic diagram overleaf) is a cooling or heating system in which an ethylene or propylene glycol-water solution is circulated throughout the building or through cooling/heating coils in an HVAC system in order to provide space cooling/heating without the inherent risk of freeze damage. �P��"C�Ji*�����B��#ّa��7Hpj-���GN��H[yu;^��!���Hf��f�l�G&�@��v`�q�Itj.�Ƿ#g���Ϋ���+�5��w@�#,��uuU�84�W�v$�#��#$:5���l�W*T�D�#tE�P�� *�5LU�#84�H�:R�%��#$�C��#{v$T���tju*P��=D��U7�F�2+Q/H�U���K�Sk�. 0000012472 00000 n Propylene Glycol To Water Ratio Chart.

The calculator and the chart provide the same information, just displayed in different ways! 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. 0000033579 00000 n 0000017240 00000 n 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° 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. 0000077114 00000 n The closer you are to half water and half antifreeze, the more effective it is. 0000012306 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. 0000055444 00000 n 0000036528 00000 n 0000051898 00000 n Propylene Glycol 95.5 94.0 Inhibitors & Water 4.5 6.0 Color Water White Fluorescent Yellow Specific Gravity (at 60/60°F) 1.046 – 1.056 1.053 – 1.063 pH of Solution (50% glycol) 9.5 – 10.5 9.0 – 10.7 Reserve Alkalinity (min.) 0000064732 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. If 100 per cent glycol is purchased then on-site mixing is required, and this can cause issues if not done properly. 0000011765 00000 n 0000046989 00000 n It is necessary to add water or glycol to maintain proper freeze point temperature. 0000032908 00000 n 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. 0000019314 00000 n 0000025084 00000 n Glycols are heavy, syrup like fluids at full concentration, and become thinner when mixed with water. However, the mixed solution of water-glycol will be thicker, heavier, than the water alone was. 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. 0000022592 00000 n Propylene glycol is also used to make polyester compounds, and as a base for deicing solutions.
