Are there any recommended brands? There is a small percentage of propylene glycol based coolant on the market. Hydronic fluids are heat transfer fluids composed of three key ingredients: Water, to provide heat transfer. 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. A major change in radiator gaskets in the 1950s led to the development of the radiator cap, which allowed pressurized coolant. Water is nature’s heat transfer fluid, a liquid used since the dawn of time to heat and cool. and existing ethylene glycol (EG) products designed for use in heavy duty engines. 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. Ethylene glycol is produced when a reaction takes place between the ethylene oxide and water. Looks like AMSOIL makes Propylene Glycol based coolant. Ethylene Glycol is most commonly used as an antifreeze in commercial and industrial applications. Uses. Propylene Glycol. In applications where toxicity is NOT a concern, ethylene glycol is often the heat transfer fluid of choice. Ethylene glycol vs propylene glycol. This reaction can be catalyzed by either acids or bases, or can occur at neutral pH under elevated temperatures. strength of a known Glycol. AMBITROL™ Inhibited Propylene Glycol-based Coolants are recommended for applications where incidental contact with drinking water or ground water is possible, or where regulatory guidelines on ethylene glycol make the use of propylene glycol coolants preferable Propylene glycol-based coolants are also especially effective in reducing cavitation Here it shows that the solution could be 30% Propylene Glycol. Later, ethylene glycol was developed as the main antifreeze. It's not totally safe however, and you should ensure that you don't have any coolant leaks. Propylene Glycol is een cosmetische vorm van minerale olie en wordt ook wel genoemd als een goedkoper alternatief voor glycerine, dat bovendien sneller in de huid trekt. C 2 H 4 O + H 2 O → HO−CH 2 CH 2 −OH. I am thinking of switching over to Propylene Glycol based coolant to be safe. It’s a synthetic liquid that has many industrial applications. Propylene Glycol… For water free of impurities, the freezing point is 32°F which is much higher compared to pure ethylene glycol which changes to its solid-state at 8.9°F. But the fact the two interact at all is why PrimoChill says to not use it, and will void your warranty if you did use ethylene glycol coolant with their tubing. There are two main types of glycols, ethylene glycol and propylene glycol with propylene glycol available in … Water vs. Glycol Heat Transfer. A propylene glycol base engine coolant is described which assists the heavy duty user in solving many current problems related to cooling $23.99 $ 23. It’s usually advertised as a non-toxic alternative to ethylene glycol. Is anyone using Propylene Glycol based coolant here? Propylene anti-freeze is going to be much more expensive since that particular compound is used in many other applications. Instead stick to propylene glycol based coolants (also called propane diol) or glycerol-based coolants (Mayhem's X1, for example) if … While you might see propylene glycol described as an organic compound, this does not mean it’s naturally occurring. The ability of ethylene glycol and propylene glycol to lower the freezing point of water constitutes the most important physical property in coolant applications and the primary reason for using glycol-based heat transfer fluids. But we now are going to use this device to identify an unknown glycol which we know to have two totally different percentages of strength. And where is the drain plug on the rad? Another option might be to drain the system and replace the coolant with Ethylene Glycol antifreeze. Undiluted ethylene glycol has a boiling point of 197.6 ° C (387.7 ° F) and freezing point of -13 ° C (8.6 ° F). Remember that ethylene glycol is a toxic substance and dispose of it as required in your community. If doing this, how does one get all the old coolant out of the system? Due to environmental concerns, the main component of the coolant was replaced by ethylene glycol. Fortunately, there are … Propylene glycol and ethylene glycol are widely used in the HVAC industry to protect systems from damage caused by freezing and corrosion. However other coolant base fluids exist such as propylene glycol and water. It freezes at 32°F and boils at 212°F. Toxicity level is one of the primary differences between propylene glycol and ethylene glycol antifreeze. For example, ethylene glycol is more efficient and works better under lower temperatures. GAIN EXPRESS 6-in-1 Automotive Car Refractometer ATC for Adblue/Antifreeze/Battery Acid/Windshield Fluid, Propylene Ethylene Glycol Cleaning Coolant Charge Specific Gravity Density Condition. Heat Transfer Performance of Propylene Glycol Versus Ethylene Glycol Coolant Solutions in Laboratory Testing 1999-01-0129 This paper describes the results of laboratory testing comparing the heat transfer performance of heavy duty radiators with Propylene Glycol and Ethylene Glycol based coolants. Propylene glycol is less toxic than ethylene glycol and has perceived environmental benefits; however, these are off-set by higher cost. To extend this range, other chemicals like ethylene glycol and propylene glycol are added. When a glycol-water mixture is altered, the freezing point of the coolant also changes. Ethylene or propylene glycol, to depress the freeze point of the fluid. The primary difference between propylene glycol and ethylene glycol is toxicity and heat transfer characteristics. Propylene Glycol vs Ethylene Glycol Toxicity. The boiling point reduction may result in undetected coolant boiling, since many engine temperature warning devices are set at 260°F, and weak coolants will boil before they reach this temperature. Are there any drain plugs low down on the Kubota engine block? Nemco Propylene Glycol Inhibited and Dyed Industrial Antifreeze & Coolant is a non-toxic heat transfer fluid blended with propylene glycol (PG) and a very low percentage of inhibitor. June 17, 2015 Newsletter Dynalene. A balanced inhibitor system, to protect common metals of construction. Ethylene glycol and its oligomers are preferable as a starting material instead of water, because they allow the creation of polymers with a low polydispersity (narrow molecular weight distribution). Freeze protection, as the graphs illustrate, show that maximum protection is achieved with Ethylene Glycol Coolants at 67% antifreeze and Propylene Glycol coolants at 100% antifreeze. Rather the term organic compound refers to the fact that it contains carbon. Some countries require the addition of a bittering agent to make antifreeze unpalatable to animals. Ethylene Glycol: The molecular weight of ethylene glycol is about 62.07 g/mol. Ethylene glycol and propylene glycol are the major constituents of antifreeze. Propylene glycol is an alcohol that absorbs water and mixes completely with many solvents. This basic formula is ideal for the user who wants to modify with additional treatment for pH and corrosion prevention requirements of various heating/cooling systems. This syrupy fluid isn’t as hazardous as ethylene glycol. Ethylene Glycol vs. Propylene Glycol vs. Food Grade Glycol. Operating an automobile without proper antifreeze can cause permanent damage, so testing ethylene and propylene glycol is an important component of proper vehicle maintenance. When a reaction takes place between ethylene oxide with water, the ethylene glycol oligomers or the ethylene glycol, it gives rise to polyethylene glycol. One option is to buy a Refractometer tester to test the Propylene Glycol. Production Industrial routes. The bad news is it is the red Walmart RV type (actually it's Camco brand), which uses denatured ethanol instead of propylene glycol. Glycols are normally used for industrial HVAC, Process cooling/heating, and antifreeze. Catalyst: Both acidic and basic catalysts are used for the production of ethylene glycol. There are also coolants made with ethylene glycol and propylene glycol, and each one has its own benefits and downsides.
