Blended with propylene glycol or ethylene glycol base, MAXTECH HTF can increase system performance and longevity while … ... anticipated temperature (also known as the burst point) by adjusting the antifreeze mix ratio, or the concentration of glycol in the heat transfer fluid. To be able to transfer the same number of B.T.U. Water is nature’s heat transfer fluid, a liquid used since the dawn of time to heat and cool. The term “glycol” is used when there are two hydroxyl groups present in neighboring carbon atoms. For example, freeze point depression is much more effective using ethylene glycol – so more propylene glycol would be required to maintain the same freeze point as ethylene. and toxicity. Both glycol based fluids can provide fluid freeze protection to -60F and system burst Conclusion. Heat transfer fluids One substance - multiple benefits. For these reasons, we do not recommend uninhibited glycols be used for HVAC heat transfer. For many heat-transfer applications it is necessary to use a heat-transfer fluid with lower freezing point than water. All of us at Recochem are committed to service and quality. Significantly less viscous (lower viscosity) than propylene glycol, especially at sub-zero temperatures. Table 2 shows the relative heat transfer of the two Glycol solutions compared to water for various coolant flow rates, further illustrating that the heat transfer perfor-mance of this downflow radiator is considerably less when using the Propylene Glycol solution than when using the Ethylene Glycol solution at coolant flows below 5.05 L/s (80 gpm). The other side is that I in my first car - a '66 Impala with a 327 engine - I changed the anti-freeze (ethylene glycol) twice a year. Whereas ethylene glycol would be used in closed systems and in controlled industrial applications. If a substance like glycol (ethylene or propylene) is mixed with water it in effect lowers the heat capacity of the liquid (.97-.93) depending on the concentration. Heat Transfer Fluids (LTHTFs), which are described in this brochure. Glycol Capacities and Correction Tables The charts, above, illustrate the differences between propylene based and ethylene based glycol. Dynalene Propylene Glycol is an inhibited non-toxic propylene glycol heat transfer fluid which offers users a stable, safe, and efficient product for applications where freeze protection is needed. Heat transfer efficiency/capability: better: less: Ethylene glycol has superior heat transfer efficiency due to lower viscosity - but more fluid must be circulated to transfer the same amount of energy since Propylene glycol has higher specific heat. Ethylene glycol-based glycol-based fluids. It is clear, colorless and practically odorless liquid completely soluble in water. There are two main types of glycols, ethylene glycol and propylene glycol with propylene glycol available in industrial and food grades. ThermalStar® is the propylene glycol based heat transfer fluid manufactured by Thermal Fluids and is widely used in secondary cooling and heating applications specifically where incidental contact with humans, food, or beverage products may occur. Propylene Glycol: Propylene Glycol is used as a solvent for intravenous, oral, and topical pharmaceutical preparations. They are alcoholic compounds due to the presence of –OH groups. Identify glycol to water ratio. Depending upon the application, PSC offers Heat Transfer Fluids in varying viscosities and degrees of thermal stability. Ethylene glycol-based fluids are less viscous than propylene glycol-based fluids. Hydronic fluids are heat transfer fluids composed of three key ingredients: Water, to provide heat transfer Ethylene or propylene glycol, to depress the freeze point of the fluid. Ethylene vs. Propylene Glycol Typically either ethylene glycol or propylene glycol are used in HVAC closed loops, with the type of glycol and its concentration determining the freeze point and other physical properties (see Table One). However, due to its moderate toxicity, it is subject to reporting requirements in the event of a spill or discharge (> 5,000 pounds). Viscosity: lower: higher: Propylene glycol increases major head loss in the systems. Propylene glycol (PG) has become the most common heat transfer fluid used in closed-loop solar heating systems that contain antifreeze. It transfers heat better than propylene glycol, and can function at temperatures as low as -100º F. Ethylene Glycol is an excellent choice for protecting natural metals. differences between ethylene and propylene glycol fluids: viscosity and toxicity. Dynalene offers pure ethylene glycol that is available in technical grade. Since we recommend propylene based glycols because of their non-hazardous nature, we must be aware of the effects on the standard refrigeration heat … Their molecular formulas are different; thus they have some different physical properties. In food processing systems the common heat-transfer fluid is based on propylene glycol. Propylene glycol, another common coolant, has an even lower specific heat… Read More Regarding base fluid, conventional heat transfer fluids such as water, ethylene glycol or propylene glycol are usually used as single base fluids or single phase liquid mixtures. Between the two, ethylene glycol (C 2H6O2) is a better heat transfer fluid than propylene glycol (C 3H8O2). with your system prior to installing ethylene glycol. High viscosity fluids require greater pumping-energy and therefore cost more to run. Ethylene glycol is commonly used in applications where efficiency is important and there is no human or animal contact due to the toxicity of the ethylene glycol chemistry. Ethylene Propylene Ethylene Propylene Glycol Glycol Glycol Sol. The specific heat capacity of ethylene glycol–based water solutions is less than that of pure water. It is for this reason that ThermalStar is produced using only new GRAS propylene glycol. Ethylene Glycol based water solutions are common in heat-transfer applications where the temperature in the heat transfer fluid can be below 32 o F (0 o C).Ethylene glycol is also commonly used in heating applications that temporarily may not be operated (cold) in surroundings with freezing conditions - such as cars and machines with water cooled engines. Therefore, they generally provide superior heat transfer efficiency and better low temperature performance and are preferred for most heat transfer applications. C 2 H 4 O + H 2 O → HO−CH 2 CH 2 −OH. Its common use is for heat transfer for things such as hydronic, heat pump, and solar heating systems. In HVAC applications, ethylene glycol is more widely used because of its lower cost, lower viscosity and better heat transfer properties. No order mins. Heat transfer performance comparison of propylene glycol and ethylene glycol solutions. This can be used as a raw material in a number of different applications or as a heat transfer fluid. Propylene and Ethylene glycol are commonly used heat transfer fluids for protection in Industrial and Commercial closed loop, water based HVAC, and cooling systems. Best heat transfer rates of all glycols and often selected ahead of propylene glycol for this reason. Ethylene Glycol - key benefits. Ethylene glycol is primarily used in antifreeze formulations (50%) and as a raw material in the manufacture of polyesters such as polyethylene terephthalate (PET) (40%). In engine coolants, propylene glycol is mainly used to reduce the freezing point of the liquid, thus preventing the cooling system and the engine from corrosion, overheating and freezing. Ethylene glycol and propylene glycol are organic compounds with alcohol functional groups. 877.244.5525 (U.S.) Propylene glycol is much less toxic than ethylene glycol. Ethylene glycol and propylene glycol are organic compounds. Glycols are normally used for industrial HVAC, Process cooling/heating, and antifreeze. Figure 1. Glycol Sol. MAXTECH HTF is formulated with high performance, industrial phosphated inhibitor chemistry to guarantee optimal heat transfer efficiency.
